Hybrid Pocket takes advantage of Pockets high base values to make use of both their Spirit and Gun potential. We start with Spirit early and use the game state to decide where to end up between Gun and Spirit.
All items have annotations to explain their use cases. It's formatted to be readable and usable by new players, but I highly recommend Eidorian's build for beginner Pockets. Actives can be hard to get used to if you're newer which this build heavily relies on for safety.
I recommend Shields > Armor at the moment if you need defensive itemization, but I let my actives do the tanking / evasion for me, allowing me to skip buying these items.
3rd T3 skill upgrade is up to preference but I've been doing Ult max 2nd recently if the enemy team doesn't buy debuff reducer / remover. Always Barrage first.
I take cloak first if I want to shove the wave early, and Barrage first if against short range matchups.
