so i've modified ward spells so that they drain stamina while in use instead of mana, to make stamina somewhat useful for casters, and prevent them from draining needed magicka reserves.

if a spell takes mana to channel, it will force the spell to stop being cast when you run out of mana.

i need to implement that effect for my ward spells after stamina is completely depleted, to prevent them from being channeled indefinitely regardless of stamina.

I added in a comparison value to the ward effects to require 5 or more stamina. but that only takes effect after the player STOPS channeling the ward on his own, and then tries to channel again with insufficient stamina.

any ideas much appreciated
