Hey, Sin, I have not been around in a while and just catching up if you still need help with this one.
Its true this ice power is not directable since it shoots in a straight line. Normally you could change
the ORIGIN to POS X Z Y and TARGET to POS X Z Y but not in this case.
What you CAN do, is add in another PUDDLE and then switch all of Frostburgs FX lines
(FX, FXSCALE, ORIGIN, TARGET) to reference 645 (the new PUDDLE) and use
the code below for POS. What I did was used that PUDDLE's PYR to (P)itch it forward a little to
give the angle you wanted and it will be invisible so only the FX shows. Then moved it about
to get a good position so it interacts with Frostburgs HEAL MOV.
0 645 NEW PUDDLE
0 645 NPC Puddle
0 645 POS 3083.0625 32.421875 -5201.140625
0 645 PYR -.5 -2.135302 -0
0 645 HP 100
0 645 HPMAX 100
I might have moved Frostburg around, too so here is his POS (since I was trying other things)
0 662 POS 3086.0625 28.421875 -5201.140625
Try that is see if it is what you wanted.
