Hello.
I've been playing around with Arcos recently which led to some questions about trampling.
In short : what factors influence the chances of trampling enemy?
Trampler's strenght?
Trampler's attack score?
Relative sizes of both units (is size 6 elephant better than size 4 chariot vs humans)?
Do units defend vs trampling with defence score or is protection relevant in some way?
Looking forward to some answers.
Cheers.
