Short tips, I use tp on veig couse he dont really need ignite to burst down his target, tp help him great at early when he runs out of mana that stop his Q farms. With mejaj u can help other lanes with tp and fill urs mejaj.

U will dominate mid game if u get death fire grasp fast.

I take level 2 E at level 8 couse with level 1 mostly the enemy have time to run away after stun before urs W lands.

Do urs E,W, death fire graps,R,Q combo will 98% if u dont have a terrible game kill the target.

I like veig couse his burst works on most tanks too if they not stacks massiv Mr.

BLue at 7-8 min will win lane for veig, couse he can E,W,Q harrase.

Stay back in team fights and take chance to stun and then burst down enemy ad carry or ap mid.
