By that metric, the majority of Skills are useless. The discussion concerns which is the most useless. Apotheosis is still useful, even if it's rarely used because the game is ridiculously easy.
- Blood Rain is pretty stupid.
- Snipe is so boring and restrictive considering the level requirement.
- Bleed Fire is trashy.
- Aportation in combat, lol.
- Terrain Transmutation is pretty bleh.
- Sabotage is derpy, but an interesting idea.
- Corpse Explosion - Does no damage and hard to land.
Handful of skills there that are borderline crap, made worse by the fact that memory tax is a very real thing and this game hates you having multiple skills.
I mean yeah, not all of these are great, but they all still have uses. Blood Rain can be used to create blood surfaces and actually makes enemies without physical (...wtf) armor bleed, Snipe may be boring and restrictive but it still does something, Terrain Transmutation is actually legitimately useful in a wide range of situations (go away, cursed fucking surfaces reeeee), and Corpse Explosion might not do great damage and may require corpses that are hard to come by, but they all
do something that's ultimately useful in some way.
Out of those, as contenders for most useless skills, I can only see Bleed Fire, Apportation and Sabotage, and out of those, I'd like to disqualify Apportation because it can still be useful outside of combat, I guess - although with Teleportation and Telekinesis, it's
highly questionable.
Sabotage is an interesting idea but useless in practice; you can't actually reverse-pickpocket in this game, and you not only do not have any idea if the enemy has any grenades or not (and if you do, why the hell didn't you pickpocket those grenades when you had the chance, to prevent them from using them to begin with?), but if they do have grenades, you want to have those for yourself - either by pickpocketing them in advance, or by killing the enemy before it gets to throw them. It's not only ridiculously situational and uncertain to be of any use whatsoever, but you actually (maybe, maybe not; we can't know beforehand!) demolish resources you want to take advantage of yourself.
And I had completely forgotten about Bleed Fire. That's how useless it is. It doesn't even do any damage by itself, and it only contributes to the battlefield turning into a raging inferno, and screws whomever is engaging the affected enemies in melee combat.
I have a very hard time deciding the single most useless Skill, though. Provoke, Smoke Cover, Breathing Bubbles or Bleed Fire. Unmodded, I can't find a use for any of them.
None.
