How cool is Umber Disciple?

[OldTrees1]

To the list of Stage 3 senses, add Nemesis. It's an exalted feat for rangers that, among other effects, lets you detect and pinpoint your favored enemies within 60'.

Hmm. Noted. Certainly fits since it cannot be stopped by RAW.

Hmm. Noted. Certainly fits since it cannot be stopped by RAW.

It's specially good when you have favored enemy (evil) and favored enemy (arcanists).

[Chronos]

Note that it only applies to only one of your favored enemies, so to get it to apply to Evil and Arcanists both, you'd need to take the feat twice. And I think it says in BoED that exalted feats are supernatural, so it'd be stopped by antimagic, though that's sort of the nuclear option for stopping abilities.

Personally, I think shadowpouncing is better, but if you really want a stealth pouncer, umbral disciple could be fun.

[Piggy Knowles]

Once again, though, being ethereal should block it, since nothing in Nemesis says it extends across planar boundaries.

EDIT: Sorry, this was in response to the discussion about Nemesis, not to Irk's post about shadowpouncing. That's what I get for leaving my reply box open too long...
