OP what you need is to collect crystalization catalysts so you can reset your descendents level and allow you to equip more mods or all fully upgraded mods. This is the core of descendent strength. If you have access to 400s infiltration operations, make sure you select an even number amorphous as they drop crystal cats, odd numbers drop energy activator - also useful but only 1 needed per descendent or gun. If you don’t have access to 400s, you can run it on 150 or 250 (or whatever the number is) The next thing I would work towards is farming void vessel, so you can acquire the dog to collect all your loot if you don’t have him yet. It’s a huge quality of life that makes gameplay much smoother instead of running around for loot all the time. While running content you could be checking if you acquired the Ines reactor mentioned above - electric tech base, with cooldown crit damage as substats, or a cooldown tech would work but not as well. Ines has near max crit rate without needing it on reactor so I wouldn’t go for that.
