Merveil is a two-phase boss. In her first phase, she's a humanoid casting cold spells and summoning adds. In her second phase, she transforms into a monstrous form, dealing more cold damage and using area-of-effect attacks. Strategy: For phase one, focus on Merveil while dodging her ice spears. For phase two, prioritize movement to avoid her ground ice spells and ice nova. Cold resistance is highly recommended. Use a Sapphire Flask if you have one. Stay mobile and chip away at her health.
