Note: I don't know if this is an old idea the search didn't work
If you look at a vitapod when you on the bottom of it's info it says Dungeon Gear so I thought to my self there nothing eles (that I know of) labled Dungeon gear so what if you expanded on it
Attack pod: Has sword on top insted of a heart, would boost attack by number indicated and color
Red: Normal damage boost
Yellow: Pirecing damage boost
Purple: Shadow damage boost
Greenish Blue: Elemental damage boost
Example: A knight using a Calibur picks up a purple attack pod the Calibur will still do normal damage pluse some shadow damage
Defence pod: Has a sheild on top, would boost defence by number and color ( same as attack pod except defence)
Resitance pod: ( don't know what would go on top) boosts resitance by number and color
Green: poison
Red: fire
Purple/Pink: curse
Light Blue: freeze
Dark Blue: shock
Yellow: stun
Speed pod: Has wing on top, would make you run faster ( Don't know if anyone wants this one but it benifit strikers)
I actually like this a lot. It's like adding temporary UV's to your equips. I think for the damage ones to work, you'd have to deal with split damage type calculations, but besides that, this seems pretty good. However, I'm not sure how many people would take this over the standard vitapods.
