ALL MINK CAN DO IS RUN FAST! GHOUL CAN ALSO RUN FAST AS WELL AS DEAL MORE DAMAGE, LIFE LEECH, HEAL FASTER, TAKE LESS DAMAGE, AND LESS COOLDOWNS!!! Ghouls boosts only work at night, and the speed boost isn't as good as mink's and the life leech isn't that good, because you're only using melee skills in pvp.
