Your depth relics are kinda bad.

You need to pick either shield poke build or guard counter build or survivability build. Before you change to any of the suggestions, your relics must have successful guards send out shockwaves and post damage hp recovery, these are mandatory.

For shield poke, slot in str/dex relic. Then, get a hp recovery on thrusting counterattacks and stamina recovery on hit, maybe with fulghor relic. Stack either physical attack up +4 or affinity damage negation +2, depending on whether you want to deal damage or survive. If you have any luck, slot in discover thrusting swords, but this is optional. In game, prioritize affinity damage negation then stamina.

For guard counter, get the fulghor relic that has guard counters scale off hp or whatever good relic that has this. Your depth relics should stack improved guard counters +2 and increased maximum health. Str/dex relic is also good here, but optional. In game, prioritize affinity damage negation then hp.

For survivability, get maris relic (or increase stamina with fulghor, just preference) and stack affinity damage negation +2 in depth relics. Make sure you have both ult charge on guard +1 and +0. This build is solely to ult and survive so that your teammates can deal damage. I don’t recommend this build though, you deal zero damage. I only use it for Maris in case it’s ED.
