Hey guys,
I'm just back after months and months off of LoL. I see that a lot has changed. Many of the items I used to pick have either vanished or become something completely different, so I'm hoping you can help me catch up a little bit 
I really enjoy playing high-risk, high-reward champs like Veigar, Katarina, Orianna, Kha-zix (not AP, I know). Veigar is (for whatever reason) probably my favourite. Unfortunately my go-to items have changed since I last played, and I notice that the current flavour is to play HP-heavy.
Would anyone mind giving me some suggestions for the curent build for an AP assassin champ like Veigar?
I'm assuming I still want to get a DFG, maybe a Liandry's now as well? Rabadon's as usual, Void Staff for Mpen, Sorc's boots, etc. Does this seem solid?
Thanks in advance!
