Half of the VTD participation tokens don't make sense to me.
They are in three groups of pairs by slot, okay.
Marks, sure, whatever.
Fire Opal Orb is overly generic, but I'd rather spend effort pointing out how too generic other tokens are than this.
Ruby Ellipsoid has at least two problems and arguably three. First of all, it's in a similar pattern to the two masks ..., but it's not a mask. That's not a cycle. A cycle would be if they were all the same slot or maybe if they were three different slots. Having the masks work similarly makes sense. If all six rares worked similarly, that would make sense.
Second, the drawback is absurd. There already exist participation rares in IS that give +2 STR with the less than crippling disad of -1 AC. I don't see why the game needs yet another rare IS that gives +STR, but the disad could be -2 WIS or, if want to keep health related stuff, -3 HP as something vastly less crippling. Would make much more sense to do things like a cycle of IS that increased mental stats with the -1 AC disad or whatever.
Foggy Allure: Okay, bonus to mental attributes makes a lot of sense for things that go on face. Should be a theme across the slot. New slot, opportunity to really push mental stats. +2 CHA is currently nigh worthless, at most giving a FoP slot but usually not. The drawback is insanely negative. While would only make sense if dropped "Foggy" from the name, could just give +2 CHA and still be a bad choice. I don't expect CHA to ever really matter, but can pretend it will and give like +3 CHA with -1 INT for even more irrelevancy that also should be supereasy to code.
Sluggish Health: Far less downside than Foggy Allure, so, in isolation, it just seems to have too much downside, where like -1 REF would be more reasonable. Could be +2 CON, -1 DEX (or -2 DEX). I'd avoid masks increasing physical attributes all together, but I doubt that will ever happen both because there are so few things to modify in this game and we already have goofy stuff in head slot such as Stalker's Headband that increases an attribute not really head-like.
