ToME: the Tales of Maj'Eyal

Description for summons states that they inherit a number of your abilities, among them, armor penetration. Unless I'm missing something, this is not the case. My War hound has 10 APR, when I had 0, and another war hound (summoned later) had 10 APR, when summmoned I had 33 APR. Either the description is incorrect and they are not supposed to inherit APR from you, or the APR rating is not transfering over correctly.

This confused me too. As far as I can tell it doesn't inherit your weapons APR. It only inherits the bonuses listed under: when wielded/worn. I'm pretty sure the description is just badly worded.
