Early Bird Sacrifice

A complete, rewarding, and highly customizable replacement for the chance-based drop formula of the Artifact of Sacrifice in Risk of Rain 2!

Instead of frustrating randomness, Early Bird Sacrifice introduces a deterministic progression system that gives players early free drops, implements an escalating "tax" (kill requirement) as more items drop, scales progression based on stage clearance, and turns Elite, Boss, and Vengeance doppelganger fights into highly rewarding, customizable tactical events.

✨ Features

1. Deterministic Kill-to-Drop Progression

No more killing 100 monsters with zero items! The mod counts every kill towards your next item drop:

• Early "Free" Buffer: The first few drops in a stage (customizable, default 5) are extremely cheap, requiring only 1 kill each.
• The Escalating Tax: Every time the buffer is depleted, the required kill goal for subsequent drops increases by a customizable tax amount (default +1 kill per subsequent drop).

2. Stage Progression Scaling

To keep gameplay balanced and satisfying as you transition to later stages with much higher enemy density:

• StageBufferBonus (Default: 2 free drops per stage): Your free drops buffer size increases as you progress: BufferCount + (stageClearCount * StageBufferBonus). (Stage 1 = 5 free drops, Stage 2 = 7 free drops, Stage 3 = 9 free drops, etc.).
• StageBonusTax (Default: 1 base kill per stage): The initial kill goal scales: BaseKillRequirement + (stageClearCount * StageBonusTax). (Stage 1 = 1 kill, Stage 2 = 2 kills, Stage 3 = 3 kills, etc.).

3. Specialized Elite & Boss Rules

Make dangerous combat encounters highly impactful! Choose between three drop modes:

• percent (Default): Elites and Bosses count as standard 1 kill on the progress bar, but have an independent percentage lucky drop chance (3% for Elites, 30% for Bosses) to drop extra bonus items that do not consume your progress bar!
• extra credit: Lucky percentage drops are disabled, but Elites and Bosses count as multiple kills toward the progress bar (2 kills for Elites, 5 kills for Bosses).
• both: Both the lucky percentage drops and the extra kill weights/credits are active!

4. Customizable Vengeance Doppelganger Drops

If the Artifact of Vengeance is active, defeating your shadow doppelganger is an epic milestone:

• Spawns a guaranteed drop on death (100% chance by default, fully customizable).
• DoppelgangerDropMode Drop-Down: Configure exactly what item tier drops! Choices:
  • "Boss" (Default): Drops a random Boss (Yellow) item.
  • "Legendary": Drops a random Legendary (Red) item.
  • "Uncommon": Drops a random Uncommon (Green) item.
  • "Void Uncommon": Drops a random Void Green item (falls back to Uncommon if DLC is not enabled).
  • "Random": Performs a weighted random selection using your customized weight configurations.
• Fully Custom Weighted Probabilities: Customize weight allocations under "Vengeance Weights" in the config editor (Default: Boss 40%, Legendary 30%, Uncommon 20%, Void Uncommon 10%).

5. Seamlessly Integrated HUD Overlay

Includes a high-quality on-screen text tracker that integrates natively with the vanilla UI:

• Sits beautifully right under the teleporter objectives list.
• Automatically parents under the game's official ObjectiveCluster layout, handling scaling and alignment dynamically on all resolutions.
• Uses the exact gold-Bombardier game typography and color scheme.
• Fully resizable using GUIFontSize configuration.
