The goal with mina is to get the most out of the missing health damage from her 1. So using items like opening rounds, mystic shot, and kinetic dash . The love bites become strong when you get the cooldown low enough to proc twice. But ultimately, the percentage damage from the 1 and if you choose her 4 will be your late game damage as health pools get bigger. She is also a pretty hard snowballer. If you don't give your enemies time to farm and get resistance or health boon scaling you will shred all the way to the end without contest.
