Best, Interesting and Unique Ex & Su abilities?

[HaikenEdge]

So, this question isn't in the context of making a character in Dungeons & Dragons per se, but in the context of Jumper landing in D&D as part of a jumpchain, which itself is kind of like a single-player choose your own adventure writing prompt with sets of rules that let players follow as they travel from reality to reality.

As part of the Generic 3.5th Edition Dungeons & Dragons jump, there's this perk:


450: Supernatural or Extraordinary Ability (choose one): Pick an ability marked "Su" or "Ex" from your available Sourcebooks, such as a dragon's breath or a troll's regeneration; you now possess that ability. Supernatural abilities are magical, but not spells (and thus can't be dispelled or counter-magiced); Extraordinary Abilities are entirely non-magical and work just fine in antimagic fields. (Purchasable multiple times.)

Basically, by paying a set number of character creation points, the player can basically pick and choose to gain any Ex or Su ability...

So, what would you say are the best, most interesting or most unique Ex and Su abilities that would be good to have (maybe because getting an item or class feature the normal of it would be way too involved)? Assume it won't actually cost you anything resources within a D&D character's build, as it'll be purchased with a different kind of resource.

for Jumpchain you could probably break a lot of future Jumps with the Umbral Blot (Blackball)’s ability:

Planar Travel (Ex)
A blackball can fold space at will, allowing it to use ethereal jaunt, dimension door, greater teleport, or plane shift at will as a standard action.

If the Jump you’re in has multiple dimensions that you know exist? You can go there. Distances are no longer an issue. If you need to teleport around? You can do that. Sure, you’re not the fastest at-will teleporter, it taking a standard action is pretty time consuming. But the sheer range this gives you and its simplicity in use, and that it’s an Ex ability derived from a sentient black hole monster means it should probably work in most universes

it taking a standard action is pretty time consuming.

I mean, a full-round action is six seconds; a standard action is part of a section of that, and probably about four seconds, given you can fit two moves into a full-round action but not two standards, but that's less important because there's "Casting Animation Cancel" from Bofuri...


Casting Animation Cancel (200 CP)
Spells are slow, and you’re fast.
This cuts down the time needed to cast any spell or skill by five seconds. This means the shortest-cast spells take no time at all to cast. In addition, any gestures involved in casting those spells aren’t needed anymore, and the gestures for the spells that aren’t now instant are
simplified and shortened.
No need to worry about doing a gesture exactly right while in the middle of a backflip anymore.

By the logic of a D&D round taking 6 seconds and the fact you can fit a standard, a move and a swift into one round, you can basically use any ability that's less than a full round action to taking zero time.

There's plenty of good ones listed by type here: https://forums.giantitp.com/showthread.php?517934-The-3-5-Shapechange-Handbook

Dryads have a fun supernatural ability that lets them literally die if they're too far from their tree. I'd go with that one.

Balors have their vorpal sword listed as (Su). That seems noteworthy.

Any innate spell-like ability affected by Supernatural Transformation could work. For instance, Supernatural Transformation (Psionics) (which is a psi-like and becomes the equivalent of spell-like for anyone with the Magic mantle) would give a large number of very versatile (Su) powers at your disposal.

The tarrasque's unique form of regeneration would basically keep you from dying from 99.999% of everything.

Of course, the aleax's singular enemy would make you outright immune to any attack against your person, so long as it's not from whatever creature you designate as your singular enemy. The best way is to designate a creature that couldn't hurt you regardless -- or make it yourself, so you can harm yourself if needed (see below).

Various oozes have the split ability, allowing you to clone yourself at will, generally when you're dealt slashing damage. Combine with some way to form a hive mind with clones of yourself (see the hive mind ability bestowed by Dark Speech in the BoVD and similar).

How about various forms of shapeshifting? Phasm or protean, perhaps? Of course, a version of this could come to you via psionic manifesting, so...

Shadow Blend (Su) is an amazing ACF for Monk (Dark Moon Disciple, specifically) that gives you total concealment in anything other than full daylight. As stealth abilities go, this is basically second to none, as it can't be bypassed by true sight since seeing through the shadows isn't enough to penetrate the total concealment.

On the monster side of things, Dream Vestiges have the ability to travel to the Plane of Dreams as a move action... or if they're on the Plane of Dreams, leave it as a move action into a plane of its choice. Dream Travel (Su). It doesn't look like you can control where you come out, but you do automatically know where that will be before you travel.

Does this Jumper thing have a way to make yourself count as "a Scaled One native to Toril?" If so, you may want to open up your copy of Serpent Kingdoms to page 80 and peruse the Manipulate Form ability description.
