[Snake]

No Shu, please no, no more percentages. I still have nightmares about Bonder ._.

JOKES ASIDE!! Yes, as a professional Ether gatherer, I'd like to see my 'fated' material getting some love. Same to Orichalum, it's unique role wise, but it's fairly useless as it doesn't meet the PvP meta, there's a level cap when you get 60 and here goes the weapon's passive down the hill. (Maybe make it have a tiny chance to blind people? 3~6%? Nightflower is funny and unique too, and actually useful in a way.)

Also the regeneration idea sounds good, 'Snakes' in weeb-fu are related to those sorts of stuff, Ether material would be more of a 'spellcaster' thing, as it reduces durability and the usefulness of the said weapon in exchange for offering the user Focus, thus explaining why it's so fragile and 'ethereal' as it can repair itself.

So, tl;dr, pls dev,we (aka kunai) need this badly
