Is there a better way to collect fodder to level up the skill of the weapon except for the gem gacha and raid battle?
there are sp quests specifically for enhancements, materials and gems - which gets you more gachas.
Weapon quest only gives enhancement material, which is useless for enhancing skill level.
Options for skill weapons are gacha, disaster raids, events, material exchange.
story quests sometimes drop R weapon as well.
... my god those are some TERRIBLE base stats... 666 at LMB?
And you might not even be able to LMB her, which would leave her to around ~614ish Atk?
If memory serves, Sanahtlig calculated Yamata-no-Orochi at 0-stars is about +-0 net gain in specific circumstances. Seeing as 0-star Yamata-no-Orochi is slightly higher in base atk at 0-stars already, I don't see Vine being any better.
The question is... Sanahtlig? If somebody was crazy enough to farm a 3-star Vine for 30% Dark Elem attack, would it that be a good FriendList pick for Dark teams who have -40% Def? As in, trading 45% -> 30% Elem atk for -40% -> -50% Def?Rare mobs usually do, yes. But their appearance rate isn't anything impressive.
