The Swift modifier on Bellowing Stag causes it to deal no damage:

I tested this against a Level 1 Jammer with a Rank 5 Bellowing Stag with 38 Dark ATK and 52 Rage with and without Redgull enchantment.

Swift Bellowing Stag:
Jammer takes 0 Darkness magical damage. (Bellowing Stag)

No Enchant Bellowing Stag:
Jammer takes 65 Darkness magical damage. (Bellowing Stag)
