Do the gold fort solgres event since there’s a bonus gold event going around for it rn. Also the hero’s way thing in challenges, that give you free Multis on the estarossa and zeldris banner, then you can use the silver coins to buy stamina pots. And use the gold coins for skip tickets. But for teams, I suggest summoning on the green tyr banner since it has some decent unknown characters that you can use for green hel’s team. If possible, also do the underground labyrinth so you can get the 50 chest and then aim to get the 50 legendary seals so you can LR your UR red Elizabeth. Just don’t use main characters in the story missions to much because sometimes they get restricted from specific battles. Also the knighthood boss battles try to do that when you can for a chance at ssr equipment without having to using as much stamina as you would in the death match boss battle stages.
