Dot master
How strong brand can be: Initial damage of spells Dots: Red Buff Dragon Buff ( if ever get to it) 120 true damage over 3 seconds Liandrys Passive Posion Toad ( if you get smite). Ignite
All of these can easily be combined if you sacrificed your mobility. Most likely though people would want flash, so that leaves smite or ignite ( smite for those who break the meta and ignite for the others). How you guys think this would work out if I went brand in a game.
