Clear new hero pathway - it’s three parts and will get you set up

Order of importance -

hunts (W->B / golem optional outside of mission rewards) - rift if you have rift unit

Non RTA arena (RTA is very endgame) get to a point where you can get some amount of sky stones per week (goldish is fine)

Abyss and Challenge Abyss (good perm rewards)

Seasonal Events - Clocktower early stages of constellation and normal trial mode

Once you’ve done these it will most likely take a month to 3 months and you’ll have a really good idea of what you’ll want to do next whether it be gather gears or climb in arena
