IdleOn - Idle RPG: Bubonic Conjuror 33B EXP per Hour Guide

To reach extreme leveling rates like 33 billion EXP per hour in IdleOn - Idle RPG, you must run the Bubonic Conjuror as an active auto-combat character. This setup relies on an unbroken cooldown loop between Raise Dead and Tentecleye, backed by the Grind Time Alchemy bubble and dense World 4 monster spawns. It does not work offline, because standard AFK calculations cap your kills per hour to native map respawn timers.

The Active Respawn Loop

Active Bubonic Conjuror play bypasses standard respawn timers by manually reviving dead monsters. The engine works through a direct synergy between two key skills:

1. Raise Dead revives defeated enemies across the map instantly.
2. Persistent hazards (Chemical Warfare and Auspicious Aura) deal continuous damage, defeating the revived enemies within seconds.
3. Tentecleye rolls a proc chance on every monster death to reduce all current active skill cooldowns by several seconds.
4. When enough enemies die simultaneously, the cooldown of Raise Dead drops to zero before the previous batch disappears, allowing the skill to be cast continuously.

Talent Priorities and Cooldown Thresholds

To keep the loop running without stalling, you must raise Tentecleye high enough that monster kill counts reliably reset your full skill bar. Use World 3 Talent Library checkouts to push its maximum level cap past 200.

If Tentecleye is underleveled, its proc rate and cooldown reduction will be too low to reset Raise Dead before the skill timer expires. Once Tentecleye reduces cooldowns by 2 to 3 seconds per trigger, killing five to eight monsters in a single tick resets your entire hotbar.

Map Selection: World 4 Flombeiges

This loop requires compact, flat maps where lingering poison clouds touch every spawn point. Wide or highly vertical zones cause the automated pathfinding to waste time climbing ropes and ladders, breaking the kill chain.

• Primary Target: The Flombeige map in World 4 offers high base experience, rapid native mob density, and horizontal platforms that allow Chemical Warfare and Auspicious Aura to cover nearly every spawn node from the center platform.
• Progression Step: If your damage output cannot instantly kill Flombeiges, run the build on Clammies or dense World 3 maps until your base stats scale up.

EXP Multipliers and Active Cards

Raw kill volume provides the baseline, but reaching multi-billion hourly rates requires stacking active experience modifiers:

• Grind Time (Alchemy): Level this bubble in the Orange (Strength) cauldron constantly. It scales your active class experience multiplier. Bubonic Conjuror generates substantial liquid yields via Cranium Cooking, which should be funneled back into Grind Time daily.
• Active Cards: Equip the Moonmoon Card for base monster experience and the Crystal Carrot Card to boost active encounter rewards. Add boss or regional cards such as Chizoar or World 4 passive damage cards to secure one-shot kills.
• Unending Energy (Prayer): Grants a large active EXP bonus, but requires enough maximum HP and defense to absorb incoming hits.

Action Bar Setup and Client Performance

Place your skills on the active auto-attack bar in this exact sequence:

1. Slot 1: Raise Dead
2. Slot 2: Chemical Warfare
3. Slot 3: Auspicious Aura
4. Slot 4: Fart Spirit

Putting Raise Dead in the first slot ensures the AI prioritizes reviving monsters the moment Tentecleye finishes resetting cooldowns.

Because this strategy triggers hundreds of calculations, damage numbers, and item drops per minute, hardware lag can throttle monster spawn rates. To prevent frame drops from reducing your hourly EXP:

• Run active sessions on a PC client whenever possible.
• Configure your loot filter to hide low-tier equipment drops so clutter does not build up on the ground.
• Disable damage popups in the game settings to stabilize frame rates.
