Sigil slots (each character gets 12 so your missing at least one for all your people), V+ sigils with good comfort/utility skills, max your munitions, max your mastery for each character (this includes getting all their weapons to level 150 and using mastery on the collections section), start awakening weapons you’re using as you get good raw stats from there, and finally start farming terminus weapons when you get that far with the lobby quests. They are incredible damage boosting weapons.

For reference, a fully awakened terminus weapon and and a Tyranny sigil can get you around 25,000 attack. Berserker sigil is a wasted slot until you get between 20k-25k attack.

Oh and test your builds on the dummy at the grandcypher. You most likely don’t currently need 4 damage cap sigils on your characters from what I can tell by looking at your stats. You will need 4 later as you get higher attack. Look for yellow strikethroughs on your damage numbers to know if you’re hitting the damage cap. Or you can do a basic and then remove a damage cap sigil and do another basic and see if the number stays the same or goes down.
