Role skill
Imprint 100

Cast Invincibility is a skill in MU Online. Its main users are Crusader, Dark Knight, Dark Lord, Dark Wizard, plus a handful of other classes. There is no level gate on it, meaning it slots into builds across all stages of progression. On RiftMu its raw base damage is 38 – weapon damage, gear options and buffs all stack on top of that number. 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 RiftMu'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.
