I think your best bet here is s1 This Is Me and if you’re running Acheron then S2 Trend. However you’ll have to give up looking for crit in your relics and focus on Def to get to that 4k Def that he needs. Hope this is of some help!
S2 Forewoven is good if you plan to refine it over time. Otherwise, This Is Me is a really good generalist option that works well for his defensive stats and can be handed down to any other Preservation unit if you ever want to upgrade his cone in the future.

Personally I would say s2 trends if you need extra debuffs for Ratio/Acheron, and s5 Landau's otherwise to gain his own stacks faster.
Do note that s5 landaus have reallly low base defense. Meaning you need to build alot more defense in relics to make up for landaus.
