Skellification's pretty much the way to go, if only for hygiene reasons.  Though the first ritual that's going up is an instantaneous Command Undead, so that a stray dispel won't end with us getting eaten by my little pet.<br/><br/>In other news, I need some logistical information.  I need to be within thirty feet of the T-Rex to use my Command Undead scroll.  Is there any place within thirty feet of where the T-Rex is liable to go that provides some sort of cover or outcropping, and where I could hide a five-ton lizard?  This may take some finagling.  I'm thinking I use my Command Undead scroll to make the dinosaur my bitch, and in the same round, use my Benign Transposition wand to swap Mark and the T-Rex.  Mark immediately flies back, and Ithi or Garrett taps the dinosaur with the Hide from Undead wand.  I then give it a couple orders, put it on some sort of leash, and tap myself with the Hide from Undead wand.<br/><br/>Sound like a plan?<br/><br/>Edit: We can also toss in my Silent Image schema to whoever isn't tapping my dinosaur with the wand to maintain the illusion that the T-Rex is still there for a bit while we make our escape.
