Leech Magic Strength, one of the Ancient Curses, boosts magic damage by 2%, increasing to 8% over time, and it drains enemy magic damage by 6%, increasing to 12% over time. In PvP the enemy drain is lessened to 4% to 8%.
With Amulet of zealots equipped the magic damage boost is raised to 12%, increasing to 18% over time.
Leech curses drain one opponent. Following each kill, the leech % resets, and %'s does not carry across opponents. You can drain 6%, rising to 12% of an opponent, and upon fighting a new opponent, this drain restarts at only 6%, to re-rise in time to 12% again. Player boosts of 2%, rising to 8%, do carry across, however, providing that the player is supplied with more drains to sustain the boost.
