I test if Faruzan is well built.
Some numbers I noticed:
"51k Nahida damage, chamber 2 half 2. Floor adds 200 EM, making 800+200 around 1000 EM. Unsure if 1055+200 EM would be better.
113k or 111k Raiden ult damage after Nahida's 51k. Improved Raiden; now focus on other characters, talents, etc. Improving Raiden further is pointless unless switching to ER% sands, which increases ult damage but lowers skill damage.
64k Faruzan. No need to grind endlessly for perfection; invest time into other stuff.
