yeah that amulet on of farsight's goons runs around with got crazy good.
AUTO INCLUDE, RIGHT THERE
which begs the question, can tau still ally farsight?
as a rule you cant ally supplements, or your self.
But not sure about these guys.. i hear both ways...
I'm not sure if I'd call it auto-include. It's good, certainly, but it's not AMAZING. Especially on a Riptide, because half of it's power is now redundant with it's existing Riptide Shield Generator.
And when you consider that Tau will only ever get d6 Deny dice... it's more like a bandaid instead of surgery. As Midnight mentioned, it won't help you against Blessings, and Blessings are often better than any other negative attack with psychic powers. At most you may have enough dice to stop ONE power from really smacking you around, two if you have a lot of dice, but then so does your opponent. I haven't decided if I'm going to add it to my list yet, because I'm running 2 commanders; one from Farsight and one from Tau Empires, and I like symmetry; having one with a unique piece breaks that. I can give it to my Riptide, who acts as a central firing line, and let the bubble surround him (most likely to my other Riptides), but then the Invul gets wasted.
Honestly, my concern is that Tau just suffer too much in the Psychic phase now. Losing access to Taudar as an army now, they don't really have a reliable way to bring in psychic support. They're like the Dwarves of fantasy, except without rune priests who were specifically BETTER at anti-magic. Yes, they can still shoot the crap out of everything, but it seems like everyone else 'got' something out of 7e, but Tau lost out from not having that aspect.
And yes, I know Necrons were the same case, but I wonder if their Crypteks will get boosted next codex. And can't DE take Harlequin Shadowseers?
