If your not into the magic pen, or you don't have the runes, the setup I used to go (which is still very effective) is;
Marks x9 Magic Pen
Seals x9 HP/LVL OR x9 Mp5/LVL
Glyph x9 AP/LVL
Quint x3 FLAT AP
I typically get my sorcerer's boots before deathcap, because at lower levels people aren't going to have crazy MR, so this just increases your damage by a ridiculous amount. If you went my magic pen rune setup, with sorc boots, you will have 40 magic pen +15% pen.
Once you have 2 dorans rings, deathcap, and sorc shoes it's time to decide whether you need to start your defense item, or get a hextech revolver for sustain+more ap. Generally if I am raping, i'll go hextech, but if i'm doing bad, or other team is fed, I get that early defense.
Late game, if they have tons of MR, then for obvious reasons get a void staff. Get a BV or Zhonyas first depending if they are phys heavy or magic heavy.
ITEM BUILDS SHOULD NEVER EVER BE SET IN STONE...ALWAYS ADJUST WHAT YOU BUY TO WHAT IS GOING ON IN THE GAME.
Ignite - Pretty easy first blood, and extremely useful all game long for those annoying cows, tryns, healers, and anyone who needs to die.
Flash - Works well with your ulti, catch the enemy offguard and kill them. This spell is just too good for saving your ***, or kicking ***.
