Brian: I’ve always liked the Mystic base list “Hiding” and on it are two cool spells: 14th lvl “Merging” which is a great escape/hide spell and 13th lvl “Flattening” which makes a player 2 dimensions. How cool is that?
Peter: Mass Vibrations I, 13th level Essence Hand. Everyone in your field of vision needs to make an RR every round of fumble their weapon. It is absolutely brilliant and far better than any kind of blade turning. The first time I discovered this spell I was playing an invisible illusionist who cast this followed by a summoning spell that gave me a pair of tigers against a dozen guards. It was carnage and I don’t think any of them survived! Even the lower level spells are cool. In RM you rarely meet massed enemy so Vibrations I as a first level spell is a great defence once your caster reaches 4th or 5th level.
