Need help converting DtD to GURPS

[samd6]

Okay, Horror is also on the list for when I get money.

I'm still iffy about the how to model the 'dwarf' power, which is virtual immunity to knockback/bull rush.

Here are the rest of the races, and I think I might finish the first group of spells tonight. Does anyone know where there's a good write-up of spells-as-powers? Some of mine seem very off and kludgey
