Constitution uses

[jguy]

After finding and loving the feat Steadfast Determination, I was wondering if there were any other way to get your constitution modifier to other things, like attack, damage, defenses ect. Also, I know of Dragonfire Adept and Incarnum, but is there anything else that uses your Con for casting?

Fist of the Forest level 1: Add Con mod to AC as an untyped bonus

Binder 1: Bind Dahver Nar, add 1/2 Con mod to AC as an enhancement bonus to natural armor.
