Should I build ap or ad on varus?

It changes a lot. I think atm it’s ad again.

You can build either, each style requires a little finesse on your part though. If you're AD, you want to be weaving abilities into your auto attacks, if AP, you want to focus on stacking Blight and popping them at 3 stacks as quickly and efficiently as possible.

I really like building this when going AP-ish. I mostly go with these when I really want to lifesteal. As for the rest, crit builds mostly work anyways.

If you're bot, go AD, that role is for people who siege and take towers, so you want the auto attacks to be strong...mid you can play mage.......
