Worth to NP2 Raikou

yes. I cannot count the amount of times that lacking that extra 100% damage has prevented me from wiping out everything while event farming.

That really depends on your priorities, If it's worth it? Yes, very much so. She's one of the best, if not the best, AOE berserk in the game and NP2 is a great improvement. I spent lots of SQs for Jalter NP2 and you really feel it. Also if you grailed her i'd go for NP2.

That said we have Ishtar, Merlin, Musashi, King Hassan coming so.. yeah. I'll have to pass on Raikou because i'm F2P and all my savings are for Merlin/Hassan but if you can buy more quartz go ahead.

Just a reminder that she will have another rate up next year.

Not over other servants and to be honest, next year she gets a better rate up along Munenori, which an extremely OP ST Saber.

The difference between NP1 and NP2 is around 11k against not niche stuff, 16k against Earth&Sky or Demonic...22k against Shuten Douji because Raikou has a personal vendetta.

P.D: After testing it myself, i think it's worth to do it. Even more considering she's a generalist for both farming and hard content. NP2 Raikou is scary, she clears high hp waves more swiftly and i can only imagine how that will be for multi-boss quests. Still, if you are f2p, don't do it unless you have great favoritism (like me) because NP1 is broken already (NP2 is just going even further beyond aaa).

It is good to have her NP 2-3 since her 2-3 skill are quite related to her NP damage. Also there are actually few SSR berserker with AOE NP like her (also with huge NP damage boost), which make her tactical value further enhance if you have her np2.

But as FTP, you will make the decision.
