About

The Mercurial Gauntlet is a pure DPS check and the player’s best opportunity to showcase weapon mastery and Skill usage. Even without the threat of imminent death, Roy poses a significant challenge, requiring one’s best equipment and optimized weapon combos. Some notes about the Treasury’s playful dragon:

Roy’s claps can be iframed

  • Do not bring healers.

  • Look for when his arms are raised.

  • Claps between 15 second intervals. For Lv. 1 - 40, there are three claps total at ~0:16, ~0:31, and ~0:46.

  • If immobilized by status prior to a clap, Roy will attack immediately after regaining his senses.

Roy is susceptible to all status and does not inflict status. 

Later on, he does gain resistances that scale off his level.

The Mercurial Gauntlet is largely auto-battle-able until around Level 15.

Starting Off

Manually controlling Adventurers often yields superior DPS and SP gain, as the AI will not Force Strike or dodge to cancel long attack animations. These player-controlled optimizations will be crucial down the line as Roy's health grows. The early Gauntlet levels are easily auto-battle-able using most any powered-up team, with preference to those with status and/or 2 damage skills.

Universal Picks

Adventurers

Ieyasu never suffers from elemental disadvantage, bringing powerful Crit-enhanced Bleed to the table. If lacking a strong on-element Blade user, Ieyasu happily fills the STR Co-Ability gap and opens up the potential for high-rolled Crits to clear close rounds. 

Gala Cleo can be similarly flexed due to her Shadow attunement and generous buff zone. As with Ieyasu, Cleo's offensive Co-Ability is a welcome staple in the absence of an on-element Wand user. 

Elisanne offers reliable offensive support even during the Wind levels. Depending on the DPS's weapon class, a player's best option may be to manually control Elisanne, then swap to a DPS adventurer for Shapeshifts.  

Wyrmprints

Because Roy's damage is both predictable and avoidable, Full HP Wyrmprints are easily maintained and reach maximum value. In Dragalia's clearest instance of powercreep, Seaside Princess dethrones Evening of Luxury as Resounding Rendition's partner for the Mercurial Gauntlet. 

Happier Times is a slightly cheaper pick that almost single-handedly caps Skill Damage and offers synergistic Skill Haste.

Beach Battle is Elisanne's Best-in-Slot Wyrmprint, tightening her combos to provide even higher Brave Bastion uptime.  

Helper Skills

Brave Bastion Saves Lives

Elisanne is highly recommended for her massive Strength buff and short cast time. With three casts from a friend, Helper Brave Bastion will be active for up to 45 seconds of a level’s given minute. Helper Skills will be the primary method of iframing Roy’s claps, which occur at the 0:46, 0:31, and 0:16 marks. Melody is also a suitable stand-in if Helper Elisannes are exhausted. Alternatives for early levels include any Skills with immobilizing status or Bleed. 

Caution: Using any Helper Skill will reset combo counts to zero, regardless of cast time. For this reason, relying on Wyrmprints like Flash of Genius may not be ideal. 

Lv. 21 - 40 (Wind)

Bois

Easy mode is over. As Roy’s HP bar grows, so does the amount of min-maxing required. These levels will truly test a player’s equipment and ability to microadjust. Do not be discouraged, as a team of fully unbound 5★ Adventurers is far from necessary. In actuality, a full Flame team isn’t mandatory, and Level 40 can be cleared solely with Ifrit and a handful of 5★ Tier 3 weapons.


If lacking a MUB 5★ STR dragon or multiple MUB Ifrits, using a fully promoted Melody or Elisanne as a fourth teammate is highly recommended. Core 5★T3 weapons are encouraged on as many allies as possible, though they don't have to be fully unbound. At the very least, teammates should be given MUB 4★T3 weapons. For the following strategy, Sword users should run Skill Damage Wyrmprints such as The Shining Overlord paired with either Stellar Show or The Warrioresses for increased Force Strike damage.

Sword Lead Strat (Euden)

Although the AI is capable of Force Striking during Overdrive, manually controlling a Sword character is the optimal way to maximize DPS. Immediately pop Helper Brave Bastion to start the fight. Damage involves a repetition of 2 combo + Force Strike sequence. Use Skills off cooldown and iframe claps with Helper Brave Bastion, then Transform after Break at roughly the ~0:30 - 0:35 mark. Note, players with Elisanne in their party may wish to switch to her and Transform into Leviathan or High Mercury to inflict Bog. Use a Skill to iframe the final clap, continuing to use 2c + FS until Roy relents.

Marth Lead Strat (Last Boost)

Proceed as normal, but withhold using Helper Brave Bastion until Roy’s first and second claps. Unload all available Skills before 0:16, then intentionally tank the third clap. Lowering Marth below 30% HP is crucial for activating Last Boost, which provides a massive burst as twelve Skills ready at once. For this reason, Transforming during Break is not necessary, as Marth must be vulnerable by the 0:16 mark. Note, Roy must be in Overdrive for the clap to drop Marth into Last Boost range. At this point, the player may either Transform or continue using the 2 combo + FS sequence to eke out the last bit of Roy’s HP.

Lv. 21 - 40 (Flame)

The Boggiest Boi

Regarding Bog:

Despite the massive 50% damage boost offered by Bog, it becomes significantly harder to use as Roy grows stronger. Because of how afflictions work in Dragalia, every application increases a unit’s Res to that affliction by 20%. 

Lv. 11+ Lv. 21+ Lv. 31+
Bog Res 40% 60% 80%
After Lv. 30, Roy can be Bogged exactly once before obtaining complete immunity. With this in mind, it’s actually ideal to run without Renee, Jakob, or Waike in order to ensure that Bog is inflicted using Leviathan for optimal DPS.
Best Adventurers

Xander: Highest individual DPS, see below.

Karina: Like Xander, her Skill 1 is enhanced by the number of buffs she has. When equipped with Kung Fu Masters and Flower in the Fray, her DPS is just below Xander’s. May be replaced with Pietro for similar damage.

Elisanne: As previously explained, her STR buffs are invaluable for their potency and high uptime. 

Summer Estelle: Her Skill Damage Co-Ability is welcomed, and provides even more offensive support to rival Elisanne. May be replaced with Lily or Dragonyule Xander if running without standard Xander. 

DY Cleo: Though her DPS is only average, both Energy and Skill Shift buffs help to enhance the Skill 1’s of Xander and Karina.

Celliera: Also fairly average regarding damage, but her Co-Ability provides a solid 10% STR boost that may come in handy.

Xander Lead Strat

Xander follows the same strategy as the Wind levels, employing 2c + FS as the general purpose damage sequence. Because of his Force Strike passive, Xander can replace Stellar Show with Jewels of the Sun or Bonds Between Worlds. Skill Haste or Skill Prep take priority because over half of his DPS comes from his two damage Skills (three with Eoantide).

After breaking around the 0:30 mark, pop a Helper Brave Bastion if not already on cooldown. Transform into Leviathan and 2 combo + Skill 1 right off the bat. Now that Roy is Bogged, use the 2c + dodge cancel sequence for optimal DPS. High Mercury may also be used to apply Bog. While Transformed, iframe the last clap using a Helper Brave Bastion to optimize Dragon DPS. Return to damage as usual using 2c + FS to finish Roy off.  

Lv. 21 - 40 (Water)

Roy’s Water levels have the highest baseline HP when compared to Flame and Wind. That being said, these are the first levels that incorporate a Bleed user with elemental advantage which makes a noticeable impact. As with the Wind levels, Blade and Wand users are highly recommended for their offensive Co-Abilities. 

Notable Adventurers

Blade: Addis and his Bleed take top priority, but Melody or Ieyasu can also fill the gap.

Sword: Wedding Elisanne is by and large the preferred Sword user due to her Skill 2’s sizable 15% DEF reduction. 

Wand: Maribelle easily maintains full HP and sports DEF reduction on her primary Skill. Gala Cleo’s immense team support is an excellent stand-in as well. 

Filler: 50 MC Louise provides a solid 15% Skill Haste which helps tighten attack rotations. Lin You and Johanna act as general purpose DPS, but the former will disrupt clap timings with her Sleep and make the fight more inconsistent. Elisanne is a reliable offensive support to round out teams.  

Addis Lead Strat

Optimized Blade combos can be tricky to learn. When using the typical 5-Combo chain, one method of minimizing ending lag is the Failed Force Strike. Following the 5th hit, start then release a Force Strike before it’s fully charged (just after the directional marker appears). When properly “failed”, the 5th hit’s Blade sheathing animation will be cancelled and Addis will get a 2-hit head start on his next sequence when compared to standard AI control.

Note: If running with Louise, her Skill Haste Co-Ability will tighten combo chains to where Failed Force Strikes aren't as crucial. 

Ideally, Bamboo Cutter is used twice before Dignified Soul is ready, but the second Bamboo Cutter may be held until Dignified Soul is ready for a guaranteed Bleed application. 

Shapeshifting is generally not recommended except as extra burst to close out fights. 

Lv. 41 - 50 (General)

With 2 minutes on the clock and seven total claps to play around, Helper Brave Bastions must be carefully budgeted. There is some silver lining in that a second Transformation is possible towards the tail end of the fight, allowing powerhouses like Cerberus and Leviathan to finish off strong. 

Due to the wide variance between lead adventurers their SP costs, players will have to conduct trial runs to determine ideal Skill usage. As a general tip, it’s best to use Skills off cooldown unless another Skill won’t be ready within ~5 - 8 seconds of an imminent clap. In most cases, holding onto a Skill is worth the lost DPS in order to avoid clap damage. Since there’s usually no way to heal, tanking a clap would permanently remove the effects of %HP Wyrmprints and Adventurer passives. 

Recommended Brave Bastion usage generally centers around Transformations that take place during or just before Break. Since Dragon Skills are often used immediately upon Transforming, the only way to save teammates from claps is by using a Helper Skill. As such, optimal budgeting involves saving two Brave Bastions, casting one sometime prior to Transforming followed by another cast just before Dragon form ends. 

Despite the lack of elemental advantage, Ieyasu equipped with Shinobi is a powerful DPS filler for his powerful Crits and Bleed. If stuck on a level, successive runs will eventually result in a high Crit roll and subsequent victory.  

Regarding Wind Lv. 41 - 50

The usual Sword strats fall off significantly due to the extended timer. Many successful Lv. 50 clear teams involve similar structures:

  • Elisanne - Premier offensive support. By manually controlling Eli's weapon combos, Brave Bastion reaches optimal uptime. During or just prior to Break, switch to a DPS adventurer and Transform. 
  • Sarisse - Brings top tier DPS, team support and a Skill Haste Co-Ability, which is crucial to tightening Eli's basic attack chains. 
  • Wand user (50 mana circles) - Student Maribelle is preferred for her raw damage, but Sinoa's erratic support is an adequate stand-in. The focus remains on the flat 15% Skill Damage granted by their Wand Co-Ability. 
  • DPS - Two picks in particular stand out: Ramona and Mikoto. Both sport considerable Crit Damage and are among the strongest of the entire Flame roster. Ramona gains substantial support if running with an allied Rena since both of their Primed Abilities combo to give Ramona +23%STR/15%DEF at once. Note: if running the two sisters together, Rena should be manually controlled so as to properly double-cast her Skill 1. 

Rewards

Clearing levels will award a slew of upgrade materials, most notably an abundance of Twinkling Sands for crafting more Core 5★ weapons. A single Sunlight Stone is the crown jewel, obtained after clearing Lv. 39. This is the equivalent of rolling a dupe of any chosen 5★ Dragon and should be the ultimate goal for any players looking to conquer every element of the Mercurial Gauntlet.
