Poor I'on. All he wanted was a drink and a nice bed to rest in! xD

So a few questions:

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 [i]is[/i] 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. Side note for [@Yoshua171], is the spell indeed homing? Or is just directed at Morgan's person with great precision?

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?
