Split Shot: Farming
Bullet Lifesteal: Sustain, builds into Leech later
Increasing Spirit boosts overall strength
Duration Extender -> imbued on Jar of Dead -> Upgrade to Superior Duration makes you really annoying
Core Items
Arcane Surge: If you need more stamina. Activate before ult so it lasts longer.
Echo Shard: On Jar of Dead for more burst damage in mid-late fights.
Situational
Healing Rite while laning if needed for fast health reset
Extra Charge/Rapid Recharge are not insane but good if you quickly need more utility
Counterspell: Good against dangerous ults like Lash, Bebop, or Wraith. Good as soon as high damage or major uits become a threat
Dispel Magic: If there are a lot of status effects
Mid Game
Toxic Bullets: Biggest damage spike at this stage
Heroic Aura: Strengthens deadheads and ghouls a lot
Inhibitor: Second-largest power spike
Leech/Escalating Resilience: Increases survivability
Silencer: Completes the trio of on-hit effects
Spirit Resilience: Makes you very hard to kill against spirit-heavy heroes
Ricochet: Maximizes teamfight potential
Late Game
Boundless Spirit for more damage; otherwise, use Escalating Exposure if locking slots.
Debuff Reducer: If the enemy team relies on DoT or status effects (Infernus, Abrams, Bebop, Seven). Build into Spellbreaker or Plated Armor
Spellbreaker: Spirit teams
Plated Armor: Gun teams
