I am a bit confused. My character has Unseelie Magic (only, no other "human" magic). I understand the "with evocation's speed and methods" except for the part about drawing power for the spell.
1) Can my character draw power for a winter thaumaturgy over multiple passes like normal or does it have to be done as an evocation (all in one shot) thus limiting the strength of the spell if I don't want Winter to handle the excess (and massively increasing my debt)?
2) Can my character assist a normal (non-sponsored) thaumaturgy as long as it falls within Winter's elements (wildness, death, decay, slumber, cold)?
3) One of the issues our group came up against was we wanted to come up with a sleep spell as a non-lethal way of removing witnesses & potential victims, along the lines of the Mind Fog spell in the examples. The end result was twice the difficulty of "taking out" the entire zone. Is this correct.
4) And last of all, can a spell (either evo or thau, depending on answer to #1 same for me either way) combine 2 components in the same spell, as in a mental attack that causes stress also makes the target 'sleepy'? My reason for this is I'm thinking of a Sleep spell that wears down the target each hit vs a (weapon 6 mental attack that causes a stroke to the guard I was trying to knock out). Realistically I know that "non-lethal" CAN kill, like a stun used on someone with a pacemaker, but 'magic' should be able to avoid that. :-)
