Veigar Build Guide by
Not Updated For Current Season
Well this is my first build on MOBA fire, but anyways
Start with amplifying tome and a Mana pot. Then begin on Deathfire Grasp, then some shoes.
As you see, there are 4 rabadons, witch is great, but you might consider to remove one of them and buy a Rylai's Crystal Scepter
You should Lvl up your Q at once, that will give you the ability to farm both Ability Power and Cash/Money
When you are in a team fight, try to stun most of them ant then imidliaty cast your Dark matter, Baleful strike then primodial burst, That should instantly kill them, IF THEY ARE A MAGE, DO NOT DO THIS AT FULL HPED TANKS OR ANYTHING WITH ALOT OF HP. Also note that you do more dmg to them the more AP they have.
Heal and clarity for Veigar is important, EVEN IF YOU ARE LVL 30, USE HEAL. The heal help you out of alot of situations and things like that, and you need clarity because he is a manaburner.
When you lane, you should go premade or solomid. Veigar is a good Midlaner because of hes range, and stun. But if a tank like trynda or someone like him goes against you, try to avoid them and low them with Q.
