this is how sub dps works

i didn't want to confuse new players with tutorials , i just wanted to make simple intro to subs dps and how to pair them ,

But what skill to use to trigger the heavy buff？or its automatic when the sub dps is on the team？

using empryan set on mortefi is better than moonlit give 2.5% less attack buff but his own damage is being so good his cordinated attacks can deal a lot of damage with this set and also lupa get benefit from reso liberation using her with basic attack dmg buffer like sanhua is not good using her with changli or jianxin iis way better and her damage is not good as other sub dps characters so using her as a hypercarry is so bad use her as a sub dps with brant she can buff brant a lot his best buffer is lupa if you also have S3 lupa your brant can deal 400k-500k dmage

Cool

On ending, what do u mean about basic and atk buff with Lupa, brant, cartetya, and cantarella?
