So.....as Viktor, is it wisest to just rush all three augments because it is such a gold efficient item, or is it better to build items in between? Also, when should lichbane be bought? I know it compliments his q and burst so well, however his q is maxed second and it ranks up with level so I'm always unsire whether it's an early game, mid, or late game item. Any ideas?

You need ap for sheen / LB to work so build it mid game
The Anagram King1 votesIt really depends what you're going for. If you're missing out on farm, fear you will miss out on farm as the lane progresses, or are otherwise maxing E first, then grab the E augment nice and early. Use it sparingly, though, as it's pretty mana-intensive.
If you're top lane, I'd also advise getting the Q augment for speed ups. It's 100 MS per use for 2.5 seconds, and, often, I can go without buying boots for the entire game. :P
Lich Bane is a complimentary item. I wouldn't advise getting it until your core needs are dealt with (mr, armour, speed, AP, etc). Frozen Gauntlet, on the other hand, is an excellent early game buy. ESPECIALLY if you're maxing Q first. Late game, you can always switch it out for a lich bane if you feel like you're falling behind in damage.
Vik's augments rock, but until you're reaching higher levels, you're buying the utility - not the scaling AP. So unless you need the escape potential, or the wave clear, or the pull-in effect on your w, it is a mid-to-late game purchase.

You can really build Viktor in a variety of ways; and his high base damage and (eventually) low cooldowns means you can even go semi-tank, should you like.
He's pretty versatile. Albeit, kind've weak until he gets some levels in him.
