Only ability score rolls, the only combat utility is casting STR hex which makes shoving harder for the enemy.
Does hexing WIS make it harder for enemies to perceive my stealthed party members do you know, or is the ability check there just my characters’ stealth (vs the enemy’s perception) rather than the enemy’s perception (vs my stealth)?
EDIT Apologies for wandering off topic! Hopefully it’s just a quick aside
