[Peresvet]

Hey guys, does anyone know what level is act2 merc's Thorns aura? Does it grow in levels as he levels-up, and what is the maximum? Thanks!

[LprMan]

It gets higher as your merc levels up. Max Thorns lvl is 15 at merc lvl 75.

I see, thanks!
Is the damage returned based on the monster's base damage, or is it affected by things like amp or %damage reduce, which affect the damage the character takes?

iirc amp/decrep will affect it, but not sure. here's what arreat says.
An eye for an eye is sometimes not enough. Those who would strike the emissaries of the Light had best take warning, for retribution shall be swift and certain. The might of your blows shall be felt a hundred fold unto you!

Effect: Enemies take damage when they cause melee damage to party members.

Player vs Player: Thorns will do 1/10th the damage.

This aura will do severe damage to any monster or player that hits the Paladin with a Melee attack. Thorns will only work if the enemy actually hits you however, so consider using this when you are taking a lot of damage. If the monster is unable to hit you due to your high defense, high shield blocking, high level compared to the monster, or because you kill them before they are able to attack you, consider using a different aura. This Aura also works well in parties against any monsters that may hit your party members.

Amplify damage and any other curses which reduce Physical Resist % (behaves exactly like Elemental Resists) will increase physical damage inflicted by Thorns.
