Curses a group of enemies to make them slow, weak and take amplified damage.
Decrepify also slows the attack (except missiles from monsters), reduces the damage output of monsters and makes monsters more susceptible to physical damage.
The slowing effect of
Decrepify is a separate calculation from the slowing caused by cold damage and Slows Target By % items and effects (like, say, the
Clay Golem).
This skill does work on bosses and Super Unique Monsters.
Note that additional points increase neither the effect nor the radius, so usually, one point (with possibly +skills items) is sufficient even if you are planning to use this skill heavily. Typically you can just keep casting the spell on a target to recharge the duration since it does not cost much mana.
