Erefir can deal 351 damage in one turn with 81 accuracy, while Giyoon, thanks to his four attacks, deals 598 damage with 83 accuracy. If Firfir misses, he misses, but Giyoon would have to be incredibly lucky to miss all four times (I don't doubt him, of course, but still).
I think Reven is just trying to protect his creatures 😅
