About Max HP Boost

Max HP Boost is a skill in MU Online. Every class unlocks it after reaching its 3rd class (after the 2nd class-up quest). There is no level gate on it, meaning it slots into builds across all stages of progression. As a Master Skill Tree skill, its Damage field holds formula number 43 rather than a flat damage value – the server works its effect out from that formula. With an Imprint value of 100, 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.
