|Drain rate||200 points per minute (1 point per 0.3 seconds)|
|Effect||+2% to +8% damage|
-6% to -12% enemy damage (PvM)
-4% to -8% enemy damage (PvP)
Leech Strength, one of the Ancient Curses, boosts melee damage by 2%, increasing to 8% over time, and it drains enemy melee damage by 6%, increasing to 12% over time. In PvP the enemy drain is lessened to 4% to 8%. This prayer may be useful in combat situations.
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.
- According to the ancient hymnal, Leech Strength's verbal incantation is "Reple me fortitudo hostium." (Fill me with the strength of my enemy.)
