It just feels like a bad PC option.
Also you didn't address that you are not required to spend a feat slot on picking Entropy Elemental but can instead just sacrifice a little bit of Spirit Points to gain it whenever. And there's enough options to gain more Spirit Points to make up for the loss.
My point was supposed to be that Entropy Elemental needs to be something readily available, not somehing you can only pick at level up.
Also considering that out of 29 classes/prcs all but two gain 8 or less spirit points per level (Magitech Knight gains 10 and Soul Soldier gains 12 but is only 5 levels long), 21 spirit points is hardly a cheap price, meaning at least 3 levels of anything besides Soul Soldier. But if you still consider it too cheap, I may raise it to 30 or 40.
-Feats are a limited resource, even more than levels usually. When writing NPCs I often run out of feat slots pretty fast long before I even consider just handing out Entropy Elemental. And anybody specializing in Entropy Elemental with their base feats would just leave themselves too vulnerable to non-magic characters specializing in anything else.
Costs 21 SP instead of a feat slot, for one. Having this feat makes you no more vulnerable to non-magic foes than not having the feat considering everything else available in just your own content. No-magic item builds are super easy with most of your content (SRW, Monsters, TobHou, Pure Metal, ect ect ect).
Again, 21 SP is at least 3 levels worth of SP for anybody besides the Soul Soldier. And picking it base means a non-magic foe picked something else more widely useful like Attacker or Counter that will give them the edge if you fight.
And even beyond that it's not all sun and sunshine for an Entropy Elemental as you're making it to be. Like if the party spellcaster is sharing uber buffs. If you have perma Null Soul, you can't benefit from them. So a party of full entropy elemental would struggle heavily against a non-magic non-entropy party with even a single spellcaster to further buff them up. Yes End of Magic can dispel stuff, but that's assuming their magically buffed initiative doesn't allow them to go first and insta-smash you with all their magic buffs before you ever get a chance of using Entropy Elemental.
Is it that much to ask for a non-magic character to be a viable option?
Both my previous post and this one, I feel, kinda are making that point actually. I've been advocating non-magic characters in both of these posts. After all, a non-magic character is exactly who'd be using this feat. But it's just too much. It's like giving some one 9th level spells or higher at 1st level. Maybe a slight exaggeration but my point is there.
Is it in the same level of Wish? Shapechange? Gate?
Because actual 9th level spells would allow a 1st level character to dominate pretty much everything (gate/shapechange into a solar or a titan then gate infinite titans), whereas a 1st level character with entropy elemental still dies just fine when somebody stabs them with a rusty dagger.
Heck, a wizard with a bit more levels could do it just fine even if all their magic is shut down because they'll still have more HP and Bab to win a direct fight.
But if you have commoner 1 with shapechange/gate against non-homebrew no-magic-items epic fighter 200000000, the commoner 1 wins because infinite titans 100% of the time.
This feat is too much to be a feat. Shoot, make an actual Entropy Elemental monster for the SRW setting Maybe make a 'lighter' form of this feat based around being a survivor of an encounter with such a creature?
Yes I could make an actual monster (and maybe I still will), but then as they say as soon as I give it stats, a wizard can kill it, probably a level 1. However you can't kill a feat. Entropy is everywhere.
-Also Entropy Elemental is necessary settingwise to explain why don't people just magic up all their problems and immortal wizards don't rule everything from their pocket planes with only other immortal wizards being able to challenge them. Remember this isn't just a mecha rules supplement, is a setting on itself, and one where tech needs to be a competitive alternative to magic, and since magic is already well beyond infinite in so many ways then that means dragging magic down. My original idea was actually making it some sort of space monster going around destroying everything magic but ended up doing it as a feat so PCs could use it too.
That sounds like a far better idea than making this a PC option. At the end of the day, Entropy Elemental just feels so much like a bad PC option to make available.
Well it's also good for villains, otherwise Entropy Elemental Elder (name pending for monster version) is the only credible non-magical threat, and that just won't do. Mechas are supposed to be the stars here, not fancy trophies for spellcasters.
(also current version was changed to just berserk for 1d12 days but I can go change it back to permanent if you feel it's a better idea after all)
Temporary berserking can also have some interesting consequences though. Like, if they aren't killed before the end of it, many societal & political problems could arise such a situation.
Indeed.
