Limited Spells and Enlarge/Reduce
I'm working on converting some d20 core spells and have a few questions/comments.
Having some MP reductions for limited spells would be useful. I'm looking at a Hold Portal spell in EoMR. Move Force 2/Gen 1 to get a 25 strength holding a portal closed 30 feet from you. This seems like a pretty outrageous cost for what it does - especially considering that the same MP could be spent to move anything around in range. A "limited spell" reduction of 1 or 2 MP would seem reasonable.
Enlarge and Reduce could be made tranform effects without needing to turn into a creature that is that size. I was thinking that for 1 or 2 MP you can increase or decrease the size ategory of a creature by one step. For each level of size change the following modifiers would be applied:
* Increase: +2 Str, -2 Dex, -1 Attack, -1 AC, +5' Reach, +5' Move
* Decrease: -2 Str, +2 Dex, +1 Attack, +1 AC, -5' reach (min 0), -5' Move (min 5)
What do you think?
Edit:
I would note that I believe only signature spells should get an MP discount for a restricted effect. Spontaneous effects would never be discounted.
