Sadistic Support Seven - Triple Stun Thunderstorm

At base, Seven has one of the best guns for killing creeps/pushing/doing damage and high regen. Abuse that with Monster Rounds to shove wave as hard as you can and take guardian ASAP

Guardian should, realistically, already be dead by five to six minutes. You are now free to anchor your lane, let your duo roam, and kill waves, hit boxes, and kill camps. No, you do not need T3 Power Surge or T3 Lightning Ball to farm; let someone else take the T3 camps, hitting boxes is that much value. You are depushing waves and holding your lane as long as possible and ulting to join urn/nearby fights occasionally.

Early Unstoppable completely throws your opponents off and lets you absolutely murk a team with T3 ult. Your ult is apotheosis; kill them all. Radiant Regen will keep you alive.

You have the majority of the debuff items for your ult by this point. Seven ult does not need an immense amount of spirit; you already have a lot from Infuser, Healbane/Suppressor, and your levels/box runs. Now, we pivot a little; since we're already immortal in ult, we now add the Thunder and turn this build from evil to sadistic and cruel.

These you should get first. Plated Armor is entirely only to deal with Siphon; since you're high in the sky, and have 55% bullet resist, most of the damage you take will not be pure gun. Additionally, AP rounds won't matter with gun falloff range with being high in the sky.

Final touch items for incredibly late games. Refresher isn't very high priority, just for turbo late games.
