legions of Steel ect

[Cor2]

I think max covered everything but here you go anyway:

Mages target who ever they want. BTW Leigions of steel and the like effect multiple units at once ( they have a large Area of effect).

These spells do not wear off until the end of battle no matter how many diffrent units are targeted.

Sermon of courage effects a small number of troops , fanaticism effects the whole battlefield.
