In MU Online, Fire Burst is used as an offensive physical attack skill. It is available to: Dark Lord. The skill requires character level 74, which makes it an early‑game option for your build. It is an Energy‑based magical skill, so planning your stat points around that attribute will help you get the most out of it. Its base damage value is 150 before weapon, equipment and buff modifiers are applied. Its Imprint value is 135, which helps you compare how efficiently it benefits from Imprint or mastery upgrades versus other skills in the same tree.

These values reflect the MU Online Season 21 skill data used on MUOnline.ai, so you can check requirements before you invest stat points and plan your PvE and PvP rotations around the skills your class can actually use.
