thank nick for the inspiration of this one... after much discussion and thought i think instead of going with infinite facets we will go with a 6 interchangeable facet system where you can swap them in and out in towns or super nodes, so basically the hero can change out and add on up to 6 facets they have discovered throughout the game. NPC's will have 4 facet slots, some of which may be "locked in" as they are part of the character. In addition to the limited facet system, we will have facet sets which are basically facets that work together and give bonuses if they are equiped together. 3 grouped facets will create a minor set and 4 will create a complete set, each unlocking abilities, stat bonuses or skill sets. an example of this would be rorac's bear set where having 3 of the set would unlock the ability to climb special walls without special items, 4 would unlock the "bear" skillset which has access to numerous bear related nested skills. what do you guys think?
