So far, all this mod does is add the attribute fenris_utils:fire_resistance.
The Attribute fenris_utils:fire_resistance should optimally be set somewhere between 0.0 and 1.0 and it defaults to 0.0. The Value represents the fraction of incoming fire damage that an entity resists. If the attribute is set to 1.0, all fire damage is canceled and the entity's fireImmune method will return false, entirely cancelling the annoying fire damage animation.
