Hm. How's your ability to add status to a weapon outside rando-casts? Is it limited to death, or could you do something cuter? Just a thought for token RS Lenneth reference.
Its pretty much limited to that, yeah. FF6 doesn't have any strict status weapons, instant death aside, so the best you'll get is random spell that casts status, and you can only apply one spell per weapon in such a manner, so that really limits the options.
Random ID also fits, but feels overrepresented anyway. Offering Effect is viable (given how VP2 combat works) but a) I don't remember if you can toss that on a weapon and b) Feels like there's too much abusability potential in that, though certainly the weapon itself could be scaled for it based on BP and so on.
I think I specifically made Lenneth unable to use the Tyrant's Fist (offering clone), such that Fayt would gain an extra niche; both can use Levantine, which is like Valiant Knife+ (also randomly casts Fire 3, but that's meaningless with Offering), but only he can pretend he's Locke with it. Givnig her an offering weapon with WoB Power would be akin to an Auto Crit weapon, differences being:
-I can be more flexible with regards to special effects, like Man Eater or Drainer
-I CANNOT apply random spell casts that aren't Wind SLash, which works differently, due to Offering's nature
-Doesn't cost MP
-Splits damage randomly against multiple targets
-Makes Lenneth's Bows suck; if you have any equip that gives Offering effect, it halves ALL physical damage done by that character, not just fight. Lenneth's NVs are magical, so they'd be good, but her Bows would become fairly bad.
So in the end, it wouldn't really be that broken that early, depending on its power, and it'd have an obvious cap, cause well, if you've ever used a Normal weapon in FF6 with Offernig, you'll notiec the damage isn't very good <_<
Bare in mind that just about every Relic effect in FF6 can be duplicated on a weapon or armor, for the most part, so yeah, just assume it can be; if its something undoable, I'll just state it.
The abusability factor wouldn't be so bad, outside of MAYBE gnig Lloyd's Logic + S-Power Ring; Offernig Effect applies to the character as a whole, so Lenneth equipping a 2nd, stronger weapon could make use of it, though that's a total niche scenario that more or less limits her options and...yeah, typiacl "Genji Glove + Offering sucks" scenario, for all that it'd be slightly better here thanks to Atlas Armlet effect MAYBE!?
Regardnig Dark being under represented...
Its not as much as it use to be. In the past, it was basically Tir, T-tar summons (and by extension, Lina's rando casting of it on Gorun Nova), some of Shady's Dances, and like an odd weapon here and there...oh, and Terra's Poison Mist <_< >_>
However, I did recently add the spell Dark Holy into the mix, which can be learned by all Materia users; spell is quiteliterally just what the name implies; Dark elemental version of Holy.
I think Lenneth's GR might be Dark Elemental, but I honestly can't remember.
Though, if you mean "Darkness is underepresented early in MF6", then yeah, that's something to consider, since outside of Tir and unreliable Shady (and RANDOM T-TAR FROM SLOTS!!1!!1), its practically non-existent in the first half.
Still the Ruin's Fate idea (or whatever I name it) wouldn't be a bad idea.
Oh, ingeneral, I want all equips to show some sort of remote sense of worth. IOWs, nothing like FF6's Crystal Sword, a weapon gotten the same time as the Falchion but is worse in everyway (nevermnid the Falchion itself is useless, but that's more nature of FF6 kicking in, where as Crystal Sword is just flat out statistically pointless.) IF you see an equip that seems meaningless, like cause its totally obsoleted by options at the time or whatever, please speak up; if you are unsure if it has any special qualities, refer to the earlier list.
...that reminds me, another means of Dark damage comes from Rekscalibur random casting Black Shadow <_< >_>
