Dominate - for 0 MPs you can order someone to commit suicide.
Treat Wounds - for 0 MPs you can fully heal each member of the party over a matter of minutes.
Are there any others out there?
Other than the first two I already pointed out above, the following spells are potentially nasty at 0 MP...
Form/Set (substance) can be an unbalancing spell when it is cast at will with impunity. If using it with wood, you could break opponent's bows who are within your POW in meters, be able to warp/break open any wooden door or chest, chop down half a copse, etc. Using it with stone you could (eventually) mine your way out of any cave, open a hole in the defenses of a city wall, or even collapse buildings atop inhabitants, all at range of course. Metal has obvious applications with breaking opponents melee weapons, prison bars, chains, locks, etc again at range.
Animate (substance) could be used with something like water or sand, which the caster could send crawling under doors or through windows and then cause it to flow into the lungs of a sleeping enemy. Directed of course by his 0 MP (sense) Projection! Or how about Animate Cyanide instead?
Phantom (Touch) isn't a game breaker, but in the right situation its a continual auto 1d2 damage spell for 0 MP. No need to roll an attack and no method of resisting (save magical protection).
Fly cast on the right tool can be nasty - say a poisoned dagger for example (like the hunter-seeker in Dune) or a fire brand, jar of acid, glob of lava, poisonous animal, etc and it can be used remotely with the same 0 MP (sense) Projection trick above. However, its greatest asset is that the sorcerer can lift an ENC or SIZ up to 1 less than his POW for free. Thus he could repeatedly drop a small boulder on opponents, or (with a resist save) send an opponent vertically up a number of meters equal to his POW and drop them... Repeatedly!!! Of course, if he simply wanted to sequentially fly the entire party over the city walls one at a time he could do that for 0 MP too!
Sense Projection has already been mentioned in its capability to direct attacks remotely. In its other application it means that any door, wall, chest, box, etc can been seen/heard/etc through at will, at no cost.
Shapechange with say the species... flea into hellishly venomous scorpion? I should think that would be a nasty (and guaranteed) shock for 98% of the population in a pre-modern world. :twisted:
Smother is a big killer spell... and effectively free! You can even use it to kill dinosaurs or giants since there is no size limitation.
Spirit Projection allows a sorcerer to effectively scout through any solid object at will.
Tap... The bad old nasty spell comes into its own with sorcerers who carry around lots of little white mice. For a 0 MP spell they can regain 1 MP tapped from SIZ or STR. A perfect way of keeping your MP's constantly at twice their level... if the sorcerer was even bothering to spend any anyway - what with 0 MP Smother, Treat Wounds and Fly spells... :wink:
So those are the ones from the core rules. I'm sure that new spells introduced in the cult and magic books can be abused similarly. All it takes is a sorcerer with a little imagination!
