Hey guys, I mentioned it on the old forums, but now some numbers.
A standard, off-Silva's-shelf wolf I summoned has 20 HP. So in WM mode I wish for a large chest, a stethoscope and a SoCM and change the chest's material to ommel bone.
After eating as little as 4125g of the chest (and it's got plenty o' itself left!) I examine the wolf (the brackets indicate his stats before the power-up):
STR : 43 (10)
AGI : 107 (26)
END : 43 (10)
PER : 104 (24)
INT : 30 (7)
WIS : 21 (5)
CHA : 43 (10)
HP : 369 (20)
Keep in mind, that this particular one wasn't too hungry, if he was then he'd grow more, actually.
The best thing is that (provided You have the proper gear, and Silva likes You enough) they can be made in a couple of turns.
Permanent infravision guarantees they can spot any froggies and other invisible badness.
Maybe it could be useful against Petrus? Keep in mind that now their limb-targeted attacks can be REALLY deadly and perhaps can make someone armless ...
