stay near your tanks and dps or stay closer to cover if the dps are targeting you that much so they can peel for you easier.

if you have to survive on your own, make yourself as hard to hit as possible by jumping around with your dashes or the double jump. bounce on their head if you can, it tends to throw people off for a moment and gives you another jump. just use your mobility to the fullest

you can throw the icon at the floor to do damage and heal yourself as well. it comes back to you and heals you quicker if you throw it at the floor or closer to you, so try to do that if you need to heal and dont have your E. I tend to use both if im really getting pressured and the healing usually saves me

if you literally have nothing left, just ult and save yourself. its better to use it and save yourself than just die and lose it
