The Bonechewer, a Disgusting CR 15 Aberration, Free to Download

Hey all, it's been a bit, but please enjoy the newest U20 critter, the Bonechewer. I think you'll enjoy running this guy.

Also, know that there are four (or more) 3.5E critters being captured for the Weekly Critter Crate before March is through.

We're going to need a bigger boat...

On Fighting the Heroes with your Fists (or bite, tail slaps, and stomps)

As a general rule, aberrations do not have good combat statistics. They have one good saving throw and fair-to-middling everything else. You have to work a bit to keep an aberration competitive with ever-levelling PCs. Usually, that means spell-like abilities drawn from the great nether divide from whence aberrations sometimes come.

Or you can build one that can simultaneously swallow, fling aside, and step on up to four PCs at once. :)

Still, my Bonechewer might provide a bit of a lopsided challenge: if you're on the ground and facing it with your sword, it can bring all of its strengths to bear. If you're a level 15 primary caster or archer who is floating or flying 50+ feet above the critter and casually flinging death, well, you're looking at free XP (of course, you may have to watch your ground-bound compatriots get eaten and drowned before you're done... 300 HP is a lot).

So, Buyer Beware

As a general tip to DMs out there, be sure to choose your monsters carefully. In the right setting, with the right PCs, the bonechewer could provide quite an epic challenge as a hated scourge of an entire region. It could also simply murder your rogue while the wizard laughs.

Enjoy!
