ForceMod 3 - how does Life Leech work anyway?

[Angel Soul]

Hey folks.

Anyone played as the Tusken Raider in ForceMod 3 - CE 1.5? I play as them, and can't figure out how this Life Leech works.
It says in the instructions that "each successfull attack gives life to attacker"... but how much? I haven't seen it work for me. Ever.

Thanks in advance.

Yeah I have the same problem, and never got it to work right either, too me it seems as if it's the same as wookiee rage.
