Lokiyn, please get your own thread. The "New Topic" button in the top right corner is there for a reason.
Seriously, your dick measuring contest with SorO is getting really annoying. On both sides.
Umbral Disciple from MoI (p. 158) gives two... interesting class features.
One is Embrace of Shadows - you get an ([Invested Essentia] * 10)% miss chance that doesn't stack with any other source of miss chance. This would be really shitty if not for the fact that:
A) You get Hide in Plain Sight if you have at least 20% miss chance from Embrace of Shadows.
B) It's uncapped - if you've got a way to increase your Essentia capacity (such as Incandescent Champion or an Azurin Cleric), you can get ludicrous miss chances. I made a build once that could get a 100% miss chance for one round, 3/day.
The other class feature is the capstone; you get +5ft of reach on your turn for each point of Essentia you invest into the class feature. That's... pretty decent, actually.
Too bad the class has Medium BAB, only gives 7 Essentia over 10 levels, and doesn't advance Meldshaping. It also has two dead levels at 4th and 6th. Oh, and you can deal [Invested Essentia] Strength damage on a successful attack once per round at 9th level. Almost forgot about that.

Interestingly enough, Ironsoul Forgemaster (MoI p. 124) has class features that boost any shield, weapon, or armor you craft. The best boost is Weapon Bond, which can make any attack with a weapon daze someone, and gives you +2 damage for each Essentia invested in it. It also specifically states that you invest Essentia into them like a Soulmeld, so arguably stuff like the Incarnate's Expanded Soulmeld Capacity would apply to the capacity of your armor, weapons and shields.
Shields you can also use as weapons are clearly the winners here - you can swap between getting Resistance 5 * [Invested Essentia] against Acid, Cold, Electric, Fire, and Sonic damage, and getting +2 * [Invested Essentia] to damage with the shield, where anyone who fails a Fort save against DC 10 + [Invested Essentia] + Con is hazed for a round.
Hilariously enough, the class can give you CL 30 for the purposes of crafting magical weapons and armor - additionally, it gives you access to the Arms, Waist, Shoulders, and Heart chakras... but not any of the weaker chakras.
