Overview
Eula builds Grimheart stacks through skill and normal attacks, then unleashes a Lightfall Sword with her burst that deals massive Physical AoE. She needs Electro teammates for Superconduct RES shred and energy batteries. Pale Flame 4pc is essential for Physical DMG.
How to Play
Build Grimheart stacks with skill and normal attacks before bursting. Hold skill consumes stacks for burst damage bonus. After casting burst, continue attacking to stack Lightfall Sword, more hits means bigger explosion. Time burst detonation for maximum stacks.
Optimal Rotation
Raiden Skill, Rosaria Skill/Burst, Zhongli Skill, Eula Skill, Eula Burst, Eula NA combo (stack Lightfall), detonate, Raiden Burst. Use Raiden skill particles before Eula burst for energy. Aim for 14+ Lightfall stacks on bosses.
F2P Options
Snow-Tombed Starsilver is craftable and strong for Physical. Pale Flame domain is farmable. C0 Eula needs Raiden or another strong battery, Rosaria and Fischl help but may not be enough alone at high ER costs.
Common Mistakes
Detonating Lightfall Sword too early with few stacks. Running Eula without an Electro battery causes energy problems. Not using Superconduct, Physical RES shred is essential. Building ER sands on Eula, batteries should handle energy, focus ATK% sands.
