About Death Fire Mastery
Death Fire Mastery is a magic damage skill in MU Online. Only these classes can use it: Gun Crusher. There is no level gate on it, meaning it slots into builds across all stages of progression. Its requirements mark it as an Energy‑driven caster skill, so feed points into that attribute if you want it hitting its ceiling. As a Master Skill Tree skill, its Damage field holds formula number 257 rather than a flat damage value – the server works its effect out from that formula. With an Imprint value of 105, you can weigh how strongly it scales through Imprint or mastery upgrades against the other skills in its tree.
This data comes straight from SilverMU's live game files, so the numbers match what the server actually runs — useful for planning PvE and PvP rotations or checking a skill before you build around it. For build advice, start from your class guide instead: skills are one part of a build, not the build.
