Maxing Level and Skills

[Zhuangzi]

The spirits of Rage take a while to max out, and I usually only max the fourth rage spirit by the end of the game.

It will depend on what class you are. For a Warrior, yes, definitely take the extra rage and increased raged experience upgrades. For a Mage, the ragebox is much less important.

But in general the game is very well balanced in that the progression of levels slows down as the game progressed. So it will seem very quick to get the rage spirits to level 15 but almost the whole game to get to level 30.
