Enzo vs 400% dungeons

Hello, i've been leveling enzo and enduring legacy for genereal use purposes (or mostly the bosses). Now i like the build, as of now i'm around 12k shields (pretty low for now) but i'll get to 29k one day. One thing i'm noticing is that i lack dmg, i know enzo is a support but i see people one shotting bosses and stuff. Since i'm doing alot of 400% dungeons i was wondering if i'm building wrong since i can't dish out any substantial amount of dmg. I'll post my enzo and enduring build here too for reference on what i'm using with equipment photos too. One thing i noticed about survivability tho is that hp survives better while mobbing. I also tried a mobbing build btw i'll drop that here too. Anyone giving me some info about mayb echanging something or pointers or maybe i'm misunderstanding the character in whole ? thank you !

Regular build
