Spinfectious Sting

Spinfectious Sting is a peglin item introduced in version v0.9.01 and renamed from Ballution's Sting in v0.9.07. It is a modifier that applies Spinfection effects when the peg hits pegs; its functionality and balance have changed over subsequent updates.

Spinfectious Sting applies Spinfection status effects on contact and interacts with critical hits. Historically the item granted a certain number of base Spinfections per striking peg; in v0.9.32 its baseline was reduced by one Spinfection at every level while gaining an additional Spinfection 2 application when the hit is a critical. The net effect is that ordinary hits apply slightly fewer Spinfections but crits can cause a stronger burst of Spinfection through the added level-2 application.

Practical usage and interactions:

• Stack behavior: The item contributes its Spinfection sources alongside other Spinfection providers. Because v0.9.32 changed the per-level base, builds that relied on many small stacked Spinfections should account for one fewer base application per level compared with earlier versions.
• Critical synergy: The extra Spinfection 2 on critical hits makes critical-focused builds — those that raise crit chance or crit effects — gain disproportionately more Spinfection uptime. Prioritize ways to increase critical hit chance or to deliver fewer high-value strikes that are likely to crit rather than many low-damage non-crits.
• Timing and targets: Use Spinfectious Sting in runs where Spinfection is valuable for map control or for triggering follow-up effects that consume Spinfection stacks. The stronger crit application in v0.9.32 helps in situations where a single reinforced application is more useful than many weaker ones.
• Upgrade considerations: Since the item’s base applications were lowered in v0.9.32, consider pairing it with other Spinfection sources or modifiers that increase application count or potency to recover equivalent overall Spinfection output if you were used to the pre-v0.9.32 behavior.

Version notes:

• v0.9.01: Item introduced under the original name Ballution's Sting.
• v0.9.07: Renamed to Spinfectious Sting.
• v0.9.32: Adjusted to have one less base Spinfection at every level while adding an extra Spinfection 2 application on critical hits.
