MP Recovery Rate
From EOGamer Lineage 2 Wiki
MP Recovery Rate is the rate and amount a character regens MP. Also referred to as "tick". For example a character may gain 6 MP every 3 seconds, which is their MP recovery rate, and would usually be referred to as getting "6 MP per tick". An increased recovery rate can be more MP per tick and/or less time between MP regen. Such as 9 MP every 3 seconds or 6 MP every 1 second.
