Nature's weakness to undead and some considerations for chaos and life

[Malekron]

Nature could use a global spell that kills all undead that failed their roll to resist.


Chaos can have a spell that when killing enemy fantastic units results in them reanimated as creatures of chaos. Undead equivalent with the upkeep being research points instead of mana because chaotic eldritch beings cost the sanity of the wizard.


Life can have a city spell that converts a non fortress city to one's side.

Death could use a spell that buffs a unit's experience
Death could use a spell that summons early game flying caster units
Death could use a spell that does a certain amount of damage no matter the target's armor

See where I'm going? :D
