Are you sure? I use regeneration artefacts for my titans from Tartaran Gate - as you know, there`s a chance to summon very powerful hero instead of monster. But all summoned titans have very serious afflictions - limp, blind or feebleminded. Dressed in "full regeneraion set" (hydra skin + ring + Ivy crown), they regenerate all affliction for 10-12 turns
If regeneration works like recuperation in "world" play, why it can`t work so in combat?
