ability order
Vyper's abilities are pretty interesting because certain upgrades give really powerful effects. Your tier 2 upgrade on your 1 shreds bullet resist which can be very useful especially in the mid game. Her 2 when fully maxed lets you build up a poison on them with your bullets. This is very strong and I usually try to max this first. Your 3 gives extra slide distance and extra stamina at tier 1 and 2 respectively, meaning that Vyper is the only character in the game that can get 6 stamina without buying items. Finally, your ultimate becomes an AOE petrify at max rank, making it much better for team fights and it makes it so you don't have to hit them directly to stun. Typically I try to grab the tier 2 of my daggers and slither in the early game before fully maxing my venom and ult. Then I finish slither first and daggers last.0 items
