When fighting high end game (bosses and the like...), has anyone been able to find a way to keep a Greater Dragon healed without having Veterinary ? How ? Since the amount of hit points healed is always the same, I would imagine the most important things would be the fastest casting possible (4/6 ?) and a mana regen high enough to never run out of mana. But would it be sufficient ? Or perhaps it would also be necessary to cast spellweaving spell Gift of Renewal ? Bottom line is, can it be done somehow ?
