Besides average treasure parcels are carefully constructed so that a balanced party can carry them without quadruped assistance.
I suspect the mule was omitted from 4e for balance as much as anything else. In a 3e game of mine, players were able to loot a hundred useless +1 swords from a battlefield for a sale price of 100,000gp - all for an investment of a few hundred pack animals!
Covered.Obviously mules are incredibly powerful, even in 3.5E. By the time you apply the Half-Donkey template to a standard riding horse, the ability bonuses get all out of kelter and the racial hit dice become seriously unbalancing. And if you were to use a war horse as the base creature? Hoo boy.
But it's no big deal. Any *good* DM will simply rewrite the rules for racial hit dice, ability scores, and template application, and create a custom breed of horse to use as the base creature. Easy as pie.
JEEEEZZZZ, how much XP does a brother need to spread around before he can give XP to PirateCat again?! Can somebody cover me here? The bootpiddle plopstep donkey is pure poetry.
"It's [-]turtles[/-] mules all the way down!"The real problem is that mules can carry more weight than they, themselves, weigh. So it creates an infinite loop.
[...] You can repeat ad-infinitum, stacking your mules sky-high
You were talking about a horse/donkey hybrid?
I'd suggest resisting movement - forced or otherwise.I wonder what the Mount power for a mule would be? Maybe that's where the Groinkicker Donkeyhorse comes in.
