Which spells do folks consider worth learning or upgrading ?

[Gatts]

God's armor is stuck on max resistance, so only good about it is that it provide resistance agains all types of damage (but astral )

Target is great, but it has limits on: mind immune enemy, level 5 enemy units... than Phantom works fine... that is why I use Phantom, sooner I get used to Phantom tactics better later on... so even if phantom tactics may seem too difficult and expensive early on, you will adopt the "way of phantom" and will be excellent player till the bittern end of this game, but using target spell instead will leave you blindfooted against cyclops, dragons, archdemons etc...
