MRPG Pillars
Pillars are a lot like Skill Trees, only not, because they don't branch. Each Class and Race gets access to a series of Pillars, and gains points to spend on these at level up. Each Pillar essentially represents a single trainable skill that unlocks new abilities along the way. They are focused around the thing that makes that class great, whatever "Holds it up", much like the pillars of a great hall. Also like said pillars, they are often the only thing left standing when the rest has fallen.
Every Pillar is topped by one specific ultimate ability. Compare the Pillar to working tirelessly to master one specific move or technique, and along the way learning several useful things. Levels of pillars have no specific minimum level requirement; the idea is to be able to master a specific pillar early or gradually progress in several.
