ToME: the Tales of Maj'Eyal

First and most clearly bad, there's the interaction between Augmentation and Beyond the Flesh. Augmentation increases dexterity and strength. Beyond the Flesh replaces dexterity and strength with will and cunning. Since BtF comes with the psionic slot no possible Mindslayer build does not have it. Augmentation should have been changed or removed when BtF was made to perform stat substitution for non-psionically wielded weapons, but appears to have been forgotten.

I'd suggest some sort of multi-target melee attack replace it. Every other base game weapon user class except Skirmisher and Reaver has access to one.

My second issue is that Charged Strike following Kinetic Strike boosts Charged Shield's spike value, making it useless when Charged Shield is inactive or when Charged Shield has a talent level less than 3. This interaction, in addition to constraining builds in a class already heavy with inter-tree interactions, makes the awkwardness of the Absorption and Augmented Striking trees compound each other. It should probably not interact outside its tree.

I'd suggest making Charged Strike apply a stun to pinned targets instead of interacting with Charged Shield.

A third issue is that Reshape Weapon/Armor is still marked as a world altering talent even though it was changed to no longer actually alter items. It's not actually a bad talent interaction, but is an oversight that should be looked at.

Frenzied. Focus. Augumentation has some decent synergy with Superpower and the allegedly broken PES, both of which are good prodigy choices on MS.

Shields are some of MS's best talents (mainly because it's their only damage reduction) so they should be at least TL 3 before your more offensive talents. Additionally, the dam types that charged blocks tends to be more bursty (Lightning and Blight come to mind), so that extra spike value is appreciated when used correctly.
