1d3 minutes is a bit better but still possibly overpowered. How about 1d12 rounds?
By the way, HD should be 8d8+16=52 hp, I believe.
I guess that would work. So it doesn't affect you often, but it's a doozy when it does.
I'd hope the DM can figure out that they'll go two-handed if disarmed.
Agreed! And 1d3 minute duration.
For some reason, your post reminds me of a brilliant web ad that WotC had back in the 3.5 days. It showed a guy staring at a computer screen and said, "If you're going to sit in your basement pretending to be an elf, you might as well invite some friends."
With our recent blizzard, I've been pretending to be a white dragon for the icewalking!
Updated.
I'm not sure where the 11 hp came from, but it's fixed.
CR 6?
A cave kala stands x feet tall and weighs 200 pounds.
CR 5 and 250 pounds appeal.
I'll need to update the flavor text, as cave kala are not nomadic.
