How to Play Bonnie
Bonnie Best Team Comps
Bonnie Best Team Comp
| Esther | Flare | Bonnie |
A team comp built around the Esther and Bonnie combo. For the remaining slot, it's recommended to use a Destroyer or attacker that matches the enemy's Elemental Weakness. Bonnie boosts her own Crit Rate to deal solid DMG herself while also supporting the team.
Bonnie Best Monsterlings
Rank Effects that boost the whole team's damage output are recommended
| Nokjung | Gulgak | Amon |
For Bonnie's Monsterlings, Rank Effects that boost the whole team's Wind DMG and Crit-related stats are recommended. If possible, build your team with Wind-attribute attackers.
Bonnie Best Artifacts
Rating & Reason
| Artifact | Rating/Reason |
|---|---|
| Military Band's Offbeat Marcher | [Rating] ★★★★★ - Bonnie's Signature Artifact - Increases DEF - Grants a Wind DMG buff to the entire team with each Tag-out Skill attack |
| Celestial Halo of Life | [Rating] ★★★・ ・ - Greatly increases DEF - Increases Ultimate DMG - Grants an ATK buff to all team members upon landing an attack on an enemy |
Prioritize Artifacts that buff the character you tag in
As a Support who backs up the character you tag in, Bonnie benefits most from Artifacts that further strengthen the team. The Signature Artifact in particular has great synergy — when the Horn performance activates, allies gain a significant Wind DMG buff as well.
