Can't remember if I just glossed this over, but I don't recall any rules for summoning and forming ectoplasm, during some char creation sillyness my players had some really wacky ideas that seem almost doable under the rules. But I don't remember rules for ectoplasm, was it evocation? Thaumaturgy? Heres a couple ideas they ran by me.
Spiderman like ectoplasm slinging. All this would really be is forming a rope with ectoplasm spanning from your hand to where ever. I don't think it is too complicated.
Or an alternative to this batman grappling hook. actually having a bungee cord attached to your body and just using evocation to "throw" it a ways away hurling you with it.
One thing they haven't thought of is how to stop once they've flung themselves, but I'll let them know that once their face is in a wall.
Also one of the more wacky ideas was forming a gundam like construct of ectoplasm and then piloting it. Someone had the even more amazing notion of everyone having it in the form of ludicrous thaumaturgic spells and combining them into a megazord. Silly I know and I would never allow it, but I was still curious of it can be done in the system which would be AWESOME.
Also how would someone add flying powers to a construct?
