Amplify Damage
Required Level: 1
Prerequisites: None
This deceptively potent curse rapidly advances the age and putridity of any wound. Ordinary blows will cut through flesh and carve particularly vicious wounds that fester and seethe.
Effect: Increases the amount of damage received.
Amplify Damage lowers monster Physical Resistances by 100%. It will also remove the Immune to Physical on Monsters.
Amplify Damage allows you to quickly finish enemies off. You find Amplify Damage useful on any monsters you or your minions want to kill FAST such as Unique Bosses, Champions, Monsters that raise other Monsters such as Mummies, or any monsters that might give you a hard time.
Use Amplify Damage in parties with other players and in situations where you're doing more damage to the enemy than they are doing to you.
Does Amplify Damage work on spell damage as well as physical damage?
No, only Physical Damage.
Does Amplify Damage work with Corpse Explosion?
Partially. Corpse Explosion does 50% Physical damage and 50% Fire damage.
Decrepify
Required Level: 24
Prerequisites: Amplify Damage [1], Weaken [6], Terror [12]
This curse gives the victim a glimpse of his own mortality, briefly aging the victim. Imagining itself with an infirm body of advanced age, the afflicted believes it is no longer capable of youthful exertions.
Effect: Target's Speed, Damage and Physical Resistance -50%
Decrepify also slows the attack (except missiles from monsters), reduces the damage output of monsters and makes monsters more susceptibile 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.
i just wanna know if its worth to put more points into decrept for a summoner, since the aoe is only 4 radius
