In MU Online, Swell Mana is used as a buff / support skill. It is primarily used by Alchemist, Crusader, Dark Knight, Dark Lord and a few other compatible classes. Because it has no explicit level requirement, it can be integrated into builds across all stages of progression. It does not deal direct damage on its own and is instead focused on utility, buffs or passive power. Its Imprint value is 100, 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.
