How do you use hydras?

However, if you expect a long battle (especially when storming a fortress), you probably shouldn't use heat, cold or poison aura creatures at all, unless your entire army is immune (Caelum, Jotunheim, Abysia, some themes of Ermor) or at least resistant (C'tis - and even then, try to put poison immune (e.g. undeads) near bog beasts or where you expect the poison sling bullets to fall). Formations WILL get mixed up and jammed together in that type of fight.

Or you can just accept a certain amount of friendly fire casualties, if you are going to inflict even greater damage on the enemy. I'm not thrilled with this approach but it can work.
