Just to let you know in case you didn't, you get a great elgif as a reward for crafting at least one of every rank 6 raid sphere. The elgif is +20% to all stats and +50% bb damage. Definitely worth making all the r6 spheres for that elgif.
Colloseum is the most cancer addition this game has ever seen. I kid you not when I say that 95% or more of my matches are against a motherfucking juno-seto leader, and 2-4 azurai are on over half of the teams too. I mean, juno was a limited edition very low droprate unit, how does EVERY SINGLE TEAM HAVE HER AS A LEADER???
Came in wanting better elgifs for zenia and Elza, and ideally +1 hit for a mifune
Came out with:
20% all to anima, oracle and 2x genderless. All pretty fucking useless for me.
Got thiefs warning 4 for my farming zelnite and 10 bc when dmg exceeds 5k for Selena. 2 gems used.
Meh results.
Burned a gem, got two more...
20% all stats to light element
Demonic Life 3 - Greatly Boosts Atk/Def/Rec when HP is under 50%
I should level off of one more run, and should have stamina regen for it in ~20 minutes.
I sold a bunch of mine, and fused all of the rest onto random units mostly as a storage mechanic. If I ever really need that +100% crit damage elgif or whatever, I can emgif it off my 5* unit, but at least now I only have a few top tier elgifs clogging my inventory, and the other 40 or so are saved on my 5-6* units.
