brand is a mage, mages nuke things in range
if brand comes near walk away
if brand walks away go closer but not too close
kite him if you can, maybe you cant
use your minions
use your range
use whatever you can but don't get close if you don't have defense
This is the basics.
next decide, "do I really want to fight brand?" because if you feed him he will kill you pretty fast if you don't have defense
speaking of defense
MR and hp are nice together they scale multiplicatively but what good is this if you die instantly, same goes for sustain, you want to get some extra hp if they can 1 shot you.
Learn to farm, learn to control the wave, it goes on and on
blahblah what if you feed
if you feed GET OUT OF THE LANE!
if you cant farm then go top or bot or do whatever you can to get away from him. Don't swap just roam and kill things.
lastly, the fastest way to learn is to just watch people play.
