Whats To Do

Warhammer has its own magic system.

I think I can make it work with GURPS.

Magery levels become your Wizard levels.

Sanctity levels become your Cleric and Druid levels.

Magic Points will come with the levels and I think the cost structure is already proportionate to the original game.

Then I'll have to go through all the spells and give a write up of each in GURPS terms.  Tedious, but not too hard.

Probably simpler than trying to get the GURPS spell list to work in WFRP.

Well...  It would be simplest just to ignore the WFRP spells and use the GURPS: Magic book.

But the Warhammer spells have a distinct flavor to them and the specialized wizard classes are worth keeping.
