I cant see that you missed any, BUT you might want to redefine your Instant Movement spells
Yes they are instant spells, but are the movement they argument also instant in your game? Do you leap in the same second you cast a leap spell (Which in RM2 would allow you to make a movement action in the spell phase) or is the spell itself instantanious while the actual action is performed later (Again in RM2, that would be in the movement phase)?
This is the system that I normally use, since allowing the instant action spells to take effect immidiately will give too much power to these low level spells. (You can leap right up to or behind a archer to stop him from using the bow or simply leap to full cover)
Ofcause there is other instant movement spells, that leave no doubt about this (Leaving, long Door, teleport ect.)
