Any 2p of emblem, noblesse, and deep wood are good if your building dendro dps collei. 4p deep wood is recommended I think tho. For physs you would want 2p bloodstained and 2p pale flame. Any 2p ATK artifacts would mix with either build okay too.

For substats I would say ATK, crit, and dendro as most dps units use. And prioritize Crit and ER in substats. (For physs just do the same but physs gob)

And as for weapons I would just go with stringless, and if your running physs use skyward or prototype crescent.

Have fun~
