Enfeeble is a spell that curses all targets in an area, lowering their damage, accuracy and critical strikes. Enfeeble does not reduce the amount or accuracy of reflected damage, because reflect is not based on defender's stats.

Version history

Version	Changes
2.6.0	Increased Area of Effect mod and its progression per level doubled.
2.3.0	EnfeebleEnfeebleSpell, AoE, Duration, Curse, Hex Level: (1-20) Cost: (16-33) Mana Cast Time: 0.50 secRequires Level 24Curses all targets in an area, reducing their accuracy and making them deal less damage.Base duration is (8.00-11.80) seconds +(0-1) metre to radius Cursed enemies have (10-19)% reduced Accuracy Rating Cursed Normal or Magic enemies deal (15-29)% less Damage Cursed Rare or Unique enemies deal (9-18)% less Damage Additional Effects From 1-20% Quality: (1-20)% increased Curse DurationPlace into an item socket of the right colour to gain this skill. Right click to remove from a socket. now causes monsters to only lose 21% Critical Multiplier at Level 1 (down from 40%). This goes up by 1% every 2 gem levels, to -30% at gem level 20. A monster's base Critical Multiplier is +30%, so at level 20 this bonus is nullified. This makes it less effective when the monster has additional Critical Multiplier (through map or monster mods).
2.1.0c	Temporal Chains, Enfeeble, Curse on Hit and Blasphemy have had their quality bonuses returned to normal. A cap of 75% now applies to the action speed reduction caused by Temporal Chains and to the effects of Enfeeble.
2.1.0c	Enfeeble quality now grants 0.5% reduced enemy Critical Strike Multiplier per point of quality.
2.0.0	Mana cost reduced at all levels. The reduced critical strike chance and critical strike multiplier effects are now 25% at all levels. Area of effect increases per gem level reduced, but the base area of effect has been increased by 37.5% (from 16 to 22). It now grants 0.5% reduced critical strike chance and accuracy on cursed enemies per 1% quality instead of just critical strike chance.
1.2.0	In addition to the general curse reduction, the duration of Enfeeble has been reduced.
1.0.1	The accuracy penalty given by quality has been halved.
0.9.2	Enfeeble has been added to the game.
