Eligible classes & evolution stage
The stage is the class evolution that can use the skill: 1st = starting class, 2nd = after the second class quest, 3rd = third class, 4th = 4th class / majestic, 5th = 5th class evolution.
In MU Online, Sleep is used as an utility / control skill. It is available to: Summoner. The skill requires character level 40, 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. 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.
