Need help to keep playing

I have many hours played and already did a similar post once. That time, I started my first gem farm. Now, I have all champions with full orange set, some with higher levels. But I can't progress anymore: only a few Tales of the Champions third variants are done, Windfall and some other Vecna adventures that ask for higher levels also.

I have most feats, all blessings, all champions, most patron rewards... Not all perks, but many already. Caramon was my first 4 star event. With a lot of effort. How can I get iLevels, or what should I be doing now? Focus in silver or gold chests?
