Argenti (銀枝 pronounced Ginshi in Japanese) is a physical erudition unit.

Also, Argenti seems to make something more obvious, whereas Ayaka is a bit more subtle.

Kit

Argenti (銀枝 Ginshi) has two bursts, a 90 cost version and 180 cost version. Let's call them Q1, Q2. His E and Q are aoe. His Q2 has higher scaling than Q1. Moreover Q2 deals 6 extra instances of bounce damage to random enemies.

Also, for each enemy hit when he uses his basic atk, E, Q, he gains a stack of ascend and regenerates 3 energy. He can have up to 10 stacks, and each stack gives him more crit rate.

Ginshin is actually pretty good. He has the effect of constantly using his burst each turn. Tingyun's energy generation works well with him (as she does with many characters).

So both Argenti and Jing Yuan are premier aoe (erudition) units. Jing Yuan is a bit more viable in ST situations given his LL does have high ST scaling.

Ginshi in Genshin

There is currently no Genshin character with 2 different Q (that cost different energy). Childe's Q is 60 energy no matter which form he uses. Also there is no 'physical' vision per se in Genshin.

Ginshi E can do aoe damage. His Q1 can do an aoe nuke. His Q2 can do a bigger nuke.

For each enemy hit by AA/E/Q, he gains x energy and a stack of ascend, which increases his cr, up to 10 stacks. This effect can occur once per y seconds.
