Cryo Traveler

What it would like be if Shenhe and Aether fought together not just in lore (but in gameplay)? Answer - switch Aether to Anemo.

How it works (2 anemo, 2 cryo - crit rate buff + cd reduction)
Aether (Anemo) - 64.7 Crit Rate, 203.9% Crit Damage, 46.04 Cryo Damage Bonus (from 1151 EM Kazuha)
Shenhe (still building her) - lvl 60/70, 2456 ATK (underleveled artifacts). skill talent lvl 5
Kazuha - 4pc VV. 951 EM, 21.7 crit rate, 110.6 crit dmg
Diona - C6 (give 200 EM to Kazuha)
Not the best damage, but it works.
