Radical Exp Strategy

A customizable experience mechanism mod.

---

Features

Experience Absorb Delay

Configure how many ticks the player must wait before picking up another experience orb after collecting one.

• Vanilla default: 2 ticks
• Configurable range: 0 ~ Integer.MAX_VALUE

Direct XP Absorption

Experience from mobs killed by the player is granted directly to the player's XP bar, without spawning an experience orb entity.

• No more running around to collect scattered orbs.
• Clean, instant XP rewards for combat.
• Disable this if you prefer the vanilla orb-dropping behavior.

Aggressive XP Merge

When enabled, all experience orbs can merge with each other regardless of their individual value, and merged orbs accumulate their total XP into a single entity.

• Vanilla behavior only merges orbs with similar values — this mode removes that restriction entirely.
• One big orb = one pickup, no matter how much XP it contains.
• Ideal for farms, grinders, and large-scale mob slaughtering.

Max XP Value Per Orb

Controls the maximum amount of XP a single orb fragment can hold.

• Vanilla default: 2477
• Default (this mod): 32767
• Acts as a cap for the aggressive merge system, avoiding potential vanilla cap inadequacy.
• Higher values reduce entity count and improve performance, but may result in extremely large single orbs.

Configuration

All settings are configured via a NeoForge ModConfig file (COMMON config).
