Eclair Cookie is an Epic Support Cookie with a jam-packed kit and high base ATK, making him one of the strongest Cookies in the game. Whether you love the museum curator for his design or battle mechanics, there’s a spot for Eclair in many team comps.

Book of History: With all the knowledge and research accumulated over the years, analyzes and identifies the opponent’s weakness. Casts ‘Weakness’ debuff to three enemies with the highest ATK (targets Cookies first), amplifying the DMG they receive and dealing DMG. All allies gain an HP shield if the enemy is defeated while under the Weakness debuff.

Skill specs:

  • Cooldown: 16 secondsSingle hit DMG: 480.6 percent (+6.54 percent DMG per level)Weakness: enemies receive +25 percent DMG for 40 seconds; stacks up to four times HP Shield: +25 percent of Max HP for three secondsWeakness debuff duration: the first stack is 10 seconds, the second stack will extend it by eight seconds

Despite being a Support Cookie, Eclair can deal serious DPS with an extremely high multiplier for his Skill. His overall utility is also nearly unparalleled, with the ability to increase the team’s DMG against enemies while providing an important pillar of sustainability. He’s an all-around unit that slots well into one-shot Arena teams, World Exploration, and any other game mode.

As a Support Cookie with a massive amount of utility, the ability to spam Eclair’s Skill will greatly improve your team’s chances against battle. Equip him with a full Swift Chocolate build for optimum results.

Alternatively, if you intend to raise Eclair Cookie as a DPS in a one-shot Arena team, you may want to slot in some Searing Raspberries to improve his DMG output. Consider using three Swift Chocolates and two Searing Raspberries, or vice versa.

Don’t forget to always equip the Squishy Jelly Watch with Eclair Cookie on the team for further cooldown reduction.
