I've been pushing some more. I went out with Angela, Alantha, Storold, Raz and Vrebel today. We traveled into the Deep to adventure and apparently there was a certain treasure they were seeking. We ended up in what appeared to be a temple guarded by psionic blasting "squids" as I heard them called. Anyways, when we got into the temple I let go one of my weirds about the same time Alantha cast a wail. She got most of them, go figure, but it gave me a chance to really concentrate on stengthening my illusion. I was successful in killing one of the stragglers she left behind. I know by concentrating on the illusion I"m leaving myself more open to combat attacks, but I feel that my illusions are becoming more clear and well defined.
Oh I almost forgot, we also encountered some other creatures that try to suck your brains out, but these seemed to be a bit less dangerous than the ones in the temple later on. On these I cast two empowered fireballs and that really seemed to do the trick. My fireballs are growing in power, as are all of my spells. On these fireballs I steched my mind and narrowed my thoughts to try to maximize their affect. This leaves me more vulnerable in battle and I feel my attempt to breach their spell resistance was a bit reduced. No matter, I am on this path now and will accept these consequences.
Later on Angela wanted to show us another spot near a lake in the Deep. It seemed calm enough, until we went under the waterfall. On the other side of the waterfall we came upon a wall of demons and all types of hideous creatures from the Outside. Luckily we were prepared and were able to defeat them. I again launched one of my Weirds in an attempt to push my spell to its limits. They seemed to laugh at my illusion, and most of them resisted it before they even had to decide of my illusion's realness. Just the same, it is showing me that there will indeed be a cost in my attempt to crispin my Illusionist abilities.
Soon I hope to grow stronger as an Illusionist and I look forward to the day that I can at last maximize my spells without fail.
