Re: [Epic Creature] To bring about the fall...
Cute Crab. :)
Note that it takes a -20 on it's Grapple check if it tries to hold someone only using one tentacle.
Is there any point in noting that it is mindless?
You might want to include some semi-flavor text about the use of the carapace (ie, treasure) or remaining fluid.
It lacks any ability to attack things flying nearby -- in theory, a single archer flying 100' up kills this without taking a single point of damage.
Throwing? Rays? Being able to call down meteors? A jump-type move option every 1d4 rounds? The ability to make a single super-long tentacle? Flight?
