Yeah, done! Thanks a lot for all your advices, that probably helped me to keep a little of Stamina that stupid Blue Dragon steal me again and again (I even used a FG to replenish Sta)...
I finised the 2 lasts maps at the first try, but in the 2 first RNG trolled me a lot.
I am glad to see Events like that with a Gold KG after 2 weeks, but when the only challenge is the RNG I feel a little disappointed.
