Okay just got a 5/5 revite, and am not sure where to place it. Should I replace a 6/8 Bulwark on Arctica? Have a 4/5 revite crests set on her. Or should I change out a 6/8 scatter on Medusa? Other options are Mino,Back-up PD, or TT?
Medusa and Arctica are prime targets for revite. Both are useful in Lava 4, which is where you eventually want to be even if you're a long way from there now. Arctica is more unique, though. There will usually be only one, and with a revite 5, you'll move to the top of the list of desirable partners for that particular group configuration.
Medusa can be used in any group, and is also decent to very strong everywhere. She's huge in arena if you care, altar battles, LBF, etc etc.
You'll get more overall utility, all through the game, with a 5 revite Medusa. But you won't be as singularly special for the most important everyday play mode, Lava 4. Which do you value more? Tough choice. Especially since if someone already has a 5 revite Arctica, you may get told yours is not needed.
Perhaps the best thing to ask yourself is whether you or your guild are likely to have to depend on your Arctica to get your Lavas done. If your guild has plenty of revite Arcticas already, they won't need yours and neither will you. And if you have plenty of the very best lava heroes already, you won't need to be special to be invited.
But if you are missing some or some are going to be weak for a long time to come, or your guild has very few 5 revite Arcticas, then being a specialist will help you and maybe help everyone else too.
Well, if you are Playing Lava 3 or 4, I think anyone Out of Medusa and Artica would benefit from it. but if you are not. Then The 1st Priority should be Aries, Then Valentina and Cupid.
