Some creatures have natural regeneration, high level nature bless helps, there are regeneration items and a high level nature mage castng personal regen will get alot of regen.

That would either be a gorgon or a commander with the aegis, however the petrification is MR negatable and im not sure if it paralyzes like the spell if you pass the test. EVERY super combatant CAN be beaten, even commanders with full resistances, awesome stats, survival buffs, high regen ect have plenty of weaknesses and there are also plenty of ways to make your army resistant to almost all(cant think of any mass effect spells you cant atleast reduce the damage from) spells, or atleast ones that will affect many troops.

Also, creating and using super-combatants is just another form of strategy, you need to figure out how to get the various mages to forge the items and summon the super combatants themselves and in the case of the most powerful SCs(unique summons with artifacts) you need to find a way to get them before other people without dying.
