Low level players can leech bigfoot, anego, pianus, and other bosses just by hitting it once with the help of maple pops. With the 60/40 exp split, the leecher leeches ~1.3m exp from a single bigfoot, ~600k exp from pianus, ~1.8m from anego, while only dealing 1 damage to it. I think this is too op.
Maybe add a level check or damage check for leech.
