Uh...
[QUOTE=Rhaevnn Xeno]1) Since this spell is practically instantaneous, as well as... "homing?" I guess is the correct adjective? I am wondering if it's at all avoidable physically. Naturally, I assume the average human (or even skilled human) would be unable to dodge it, but since Morgan is a vampire/sniffer, the combination might give him the reaction time/speed to avoid the magic. This of course, is assuming that he was able to recover quickly enough to realize that he was being attacked by I'on and not focusing solely on the masked sister.[/QUOTE]
Though I wasn't familiar with the properties of that spell (meaning how fast it was moving and how effectively it was tracking), it could - in theory - be dodged. In theory, [I]anything[/I] direction-based can be avoided, which includes manifestations as projectiles, though obviously there may be cases where movement is so stupidly fast or artificial intelligence is so single-minded that it isn't practically doable.
Actually, now that we're on the subject, it's quite unusual for a mind-affecting spell to be direction-based. Such spells are usually target-based, which effectively renders them unavoidable to the target.

[QUOTE=Rhaevnn Xeno]2) Would Morgan be able to sense I'on's particular use of magic. It's true that Morgan would have already sensed a build up of his sigils and such, but can a sniffer realize the exact time magic is dispelled from its user? Or would the sniffer have to be quite skilled in his craft to realize such an occurrence is happening?[/QUOTE]
Yes, he would notice that the spell was being invoked; a sniffer's innate sense of magical energy is so keen that I'd say that any sniffer, no matter how inexperienced, would be aware of magic being cast near them. Sensing magic is what sniffers [I]do[/I], and no one does it better than them.

[QUOTE=Mercinus3]1) Do vampires have souls?[/QUOTE]
Yes, they do. As Shien said, Prophecy-vampires are not undead (which is also correctly stated to be a moot point, since undead have souls (or at least magical energy, in the case of reanimated dead), too).

[QUOTE=Mercinus3]2) Do Banes count as blessed weapons or are they just magic-imbued ones?[/QUOTE]
Bane weapons are not blessed, no (and ironically, in the Prophecy, a thing can be "blessed" by gods and demon lords alike; the property here actually describes a certain kind of ownership of the blessed object or area to the deity bestowing this blessing, which can in some cases cause the implied presence of said deity to disrupt adjacent unstable energy-structures, but more importantly renders the blessed thing very difficult to interact with to other deities (on that note, vampires are, in fact, unaffected by blessings from Rilon, just as demonspawn are unaffected by blessings from Himyth)). Bane weapons are made by fusing weapons with Stones of the Doom Mage, which are in turn made (primarily) through black magic, so their nature is (primarily) the result of mortal magic.
Now that I think about it, it occurs to me that I never mentioned that Banes are cold to the touch... and the areas near them in the immediate vicinity of the inserted Stone(s) is [I]very[/I] cold.

[QUOTE=yoshua171]1.) Can he preform a simpler spell similar to the AoE one mentioned rather than preforming 2.[/QUOTE]
I'd say Shien's answer was pretty adequate, so I'll leave it at that.
