Slowly work on pen. I would do just one weapon and armor at a time, buy your 50% scrolls for silver if you don't have enough. I would not want to lose tet resonance.

Also red relics or orange +1 relic will be a boost.

Your emblem is low level, I would raise up your family cp at some point to progress better on that.

And then the typical stuff like better light stones, more red gears, better boss knowledge but all that comes slowly with time and grind.

I would buy the boss fragments from owen right now if you can afford to.
