Thanks guys! I guess conventional wisdom is giving the firebelly an ADH, but I just can't give up those high-strength attacks. Good to know that I won't be sacrificing my regen-killing abilities entirely.
It really comes down to personal preference. Some people save the Breath for that crucial round of combat and murder something in one round after the breath has been used. Others like you suggest prefer an AHW to you can strip regen before the Ironguts get to attack. Others like myself often take the Potion of Speed so you can use the Breath or AHW to strip regen before Ogre's get to attack. Comes down to what you want to achieve or your preferred play style really.
