Which spells do folks consider worth learning or upgrading ?

[Hepasto The Terror]

This game has too many damn good spells. like have knights ans use haste on them. no dragon can face you. Use hypnosis, use fire rain, use demon's portal, use lightning, healing (against undead only) does damage costing 1 mana! (on level 3).


And Armageddon, too powerfull. Only sad part is our own troops get 1/3 damage.


for lot more details, ask me...
