Indy spell casting levels

Indies have a preset grimoire with certain spells. It never changes. It could actually use some finetuning to allow them to cast more effective spells in combat. Nothing like having F3 mages cast Fire Flies over and over and getting nothing done and Earth mages doing the same with Flying Shards...

I completely agree... for example if someone is creating a map and places a LvL_7 earth mage it's very sad to see the mage only casting 'flying shards'.
A spell like 'petrify' and other spells with high casting cost should be made available to the Independents because the default game only drops mages of LvL_2. If other more powerful spells were made available then us map makers could place powerful indy mages on the map.

If a battlefield spell costs 4 or more levels then it should be made available to the independents which would really help us map makers.
