Amazing Character Optimization: A Centaur throws a rock and does 131d6+20 damage

[Thorin]

This is an insane character optimization: the War Hulking Hurler.

At 20th level, it can throw a rock weighing more than 25,000lbs accurately dealing 131d6+20 damage to whatever target it hits.  A 25,536lb rock made entirely of granite would be 152 cubic feet (according to http://www.reade.com/Particle_Briefings/spec_gra2.html); that'd be close in size to Ustauk's car if the car was solid. 

Highlights

At this point you have a character with a 46 Str (50 with rage) and Brutal ThrowCAd allows the centaur to use Str bonus instead of Dex bonus for thrown weapons. The class feature really throw anything (Ex) allows the centaur to throw any object that would be considered a light load suffering only a -2 penalty to attack.

What's a light load for a raging centaur with a 50 Str? A medium bipedal creature's encumbrance with that Strength score is 8512 lbs (133 x 64), but because a centaur is a large quadruped, it's triple: 25536 lbs. An improvised weapon of that size does [3 + (weight/200 lbs round up)]d6 points of damage, (see Complete Warrior, page 159) which comes out to be 131d6, and a 50 Str adds 20 more points of damage (478.5 average).

Consider now that this was built entirely from WotC-created source books...

[Ustauk]

Yowza, what a munchkin!  Of course the DM could balance things out by sending a Tarrasque or elder dragon after the character...

Hmm, damage would only be as good as what every there was to throw.

Wonder how it would do in a featureless room against some sort of ooze creature.

Yes, it is entirely dependent on gear.  Mind you, it could easily carry around 125 x 200lb rocks, each of which would do 3d6+20 when thrown.  And it wouldn't even be encumbered.

Wonder how it would do in a featureless room against some sort of ooze creature.

Uhh, I wonder what *any* character would do in a featureless room against an ooze.  You're assuming the centaur isn't carrying any weapons with it, but why would a 20th-level character have no gear?  In fact, adding some decent 20th-level gear to this build makes the centaur way more kick-ass!
