Revamped Dojo

Of course, all of this is null and void if you have enough funding. This is all going off my own experience with the new Mu Lung Dojo system.

Funding... right...

A Hero can do at most 3.6m damage per Intrepid Slash (assuming so funded that even AFA hits cap).
So, at barest minimum, he needs 424 IS's to get through the Dojo. (It's actually more because the last IS on every enemy is partly wasted)
IS costs 24 MP, so our Hero needs over 10K MP just to walk through and kill unresisting enemies.
It would also take a minimum of 267 seconds, during which maxed Self Recovery would give him 2670 MP.
So, to get through Dojo without sitting down, a Hero needs at the very least 7500-8000 max MP.
Ah well, guess now we know what those Alchemy potions that raise MaxMP are really good for.
