Guild money :D

I haven't unlocked RJT, but I am using the following link as my guide on the requirements.... i have put a zeta on 'roll with the punches' and on Finn's leaf.

Hope that helps.

CommandanteJ - This will be moved to the correct sub forum first off.

Second - I checked out your squad, You have Kylo Ren Zeta'ed, so you will get BB8 no problem, his zeta makes it a walk in the park, get the rest of your FO up to 7* and you're set there. Don't waste any more materials or gear on them, even if you don't have someone at 85 with that Zylo you're golden.

For the Rey event you know which characters you need.

I did the event with a G10 Rey Scavanger, G8 Fin, G8 Vets and G8 or 9 BB8.
The hardest phase in my opinion is the 5th one, once you get past this you only need Scavanger Rey and she only needs to live a few rounds into the fight to beat the event.

Prioratize your characters as follows - Rey, BB8 & Fin evenly, VChewie, and don't really put to much into Vet Han, spoiler he dies just like the movie.

Rule of thumb if you can get everyone to gear 8 with some good Mods you can beat most events. The fifth phase is hard because you use BB8, Fin & Vet Chewie, and the FO hits pretty hard plus gains protection.

Hope this helps a bit.
