I have a gladitor that can do barreling attack well on a regular base.

I have my event trigger set on opponent is on the ground, but I can never get my gladitor to attack his opponent before switching to another event triger.

I was wondering what I should have my activity, and blood lust set at to trigger the attack, or is it an attribute I need to incresse ?

My gladitior is STR 70/ INT 68/ AGI 69/ STA 78/ Size 74/ PRE 69/ Chi 74

He uses a mace

Thanks for any feedback.
