Strategy & Tips

Sustain plus damage in one package. Heals from multiple enemies in a line. Good for survival builds.

Strategic Tips & Synergies

💡

🟢 Phase-through multiplication: Ghost's phasing allows Soul Sucker to hit 3-5 enemies per trajectory. Since lifesteal applies PER HIT, a single ball passing through 5 enemies heals you 5x compared to single-target lifesteal. Position yourself perpendicular to enemy waves so balls phase through maximum targets per pass.

💡

🟢 Density scaling: Soul Sucker's healing increases proportionally with enemy count. In waves 15-20 with 15-20+ enemies, each Soul Sucker ball can generate 5-8 healing procs per second. This inverts the usual difficulty curve—dense waves that threaten other builds STRENGTHEN Soul Sucker by providing more lifesteal targets.

💡

🟡 Ball count synergy: Soul Sucker's value multiplies with total ball count. A build with 5 Soul Sucker balls generates 15-25 healing procs per second in dense waves (5 balls × 3-5 enemies each). Prioritize ball multiplication evolutions (Mosquito King, Cell Division, Spider Queen) to maximize healing throughput.

💡

🟡 Aggressive positioning: Traditional survival builds require defensive positioning (staying away from enemies). Soul Sucker inverts this—aggressive positioning (standing IN enemy clusters) maximizes phase-through hits and healing. The more surrounded you are, the more you heal. Use this to farm high-density spawn points.

💡

🔴 Single-target weakness: Soul Sucker's strength (multi-target healing) becomes a weakness against single bosses. With only one target to phase through, you heal 1x instead of 5x. Against boss fights, Soul Sucker provides minimal sustain—pair with other healing sources (Vampire Lord, Mosquito King) or avoid relying solely on Soul Sucker for boss survival.

Best Character Pairings

These characters create exceptional synergies with Soul Sucker:

Iron Fool (A-Tier Pairing): Iron Fool's defensive passive (assumed high HP or damage reduction) synergizes with Soul Sucker's sustain-over-time healing. Defensive stats reduce incoming damage while Soul Sucker out-heals remaining damage, creating a compound survival effect. Iron Fool can safely use Soul Sucker's aggressive positioning strategy without dying during healing ramp-up.

The Shieldbearer (A-Tier Pairing): Shieldbearer's assumed shield mechanics (block X damage per hit or absorb Y total damage) complement Soul Sucker's continuous healing. Shields prevent burst damage spikes while Soul Sucker maintains HP between shield procs. This combination makes you nearly unkillable in waves 10-15 where both mechanics peak effectiveness.

The Repentant (B-Tier Pairing): Repentant's assumed sustain/defensive focus (possibly regen or damage reduction) stacks with Soul Sucker's lifesteal, creating redundant healing. While powerful, this pairing is overkill for most content—you'll be over-healing significantly. Better for extreme difficulty modes (Fast+3) or wave 20+ survival challenges.

The Itchy Finger (D-Tier Pairing): Itchy Finger's attack speed bonus increases ball frequency but doesn't multiply phase-through hits per ball. Attack speed provides linear healing increase (more balls = more hits) but Soul Sucker already benefits more from ball COUNT than ball SPEED. Better to pair Soul Sucker with ball multiplication characters than attack speed characters.

Common Mistakes to Avoid

⚠️

❌ Creating Soul Sucker too early (wave 5-7): Soul Sucker provides sustain, not damage. Creating it before establishing primary damage evolutions (Bomb, Magma, Storm) means surviving longer but killing slower, which ironically leads to taking MORE total damage over extended wave durations. Create Soul Sucker AFTER securing 2-3 damage evolutions.

⚠️

❌ Using defensive positioning: Players instinctively stay away from enemies when low HP, but this REDUCES Soul Sucker's healing by limiting phase-through targets. Soul Sucker requires aggressive positioning—standing near/in enemy clusters—to maximize lifesteal procs. Counter-intuitive but critical for effectiveness.

⚠️

❌ Pairing with low ball counts: Soul Sucker's healing scales with ball count (more balls = more phase-through hits = more healing). Builds with 3-5 balls generate 9-25 healing procs per second; builds with 10+ balls generate 30-50+ procs per second. Avoid Soul Sucker in minimal ball builds—it won't provide sufficient sustain.

⚠️

❌ Relying solely on Soul Sucker for boss fights: Boss fights typically feature 1-3 targets (boss + limited adds), drastically reducing Soul Sucker's phase-through advantage. Players who depend on Soul Sucker's wave-clearing healing often die to bosses due to insufficient sustain. Always pair Soul Sucker with secondary healing (Vampire Lord 10-stack heal, Mosquito King lifesteal) or burst damage to kill bosses before sustain matters.

Advanced Strategy

🎯

Expert-Level Optimization

⚠️ Advanced strategy combining 🟢 verified mechanics + 🟡 general principles: Soul Sucker's phase-through lifesteal creates a unique optimization opportunity—maximize healing by maximizing enemy penetration per ball. Optimal positioning: stand at enemy spawn points perpendicular to wave direction, ensuring balls phase through 5-8 enemies per trajectory as they spawn. This "spawn camping" strategy turns Soul Sucker into a preemptive healing engine: you heal BEFORE enemies spread out, maintaining full HP throughout waves. Pair Soul Sucker with movement speed upgrades (Ball Speed +%, Player Movement +%) to reposition between spawn points as waves shift—critical for waves 15+ where enemies spawn from multiple directions. The advanced Soul Sucker build combines three evolutions: Soul Sucker (multi-target lifesteal), Vampire Lord (heal 1 HP when hitting 10+ bleed stacks), and Mosquito King (lifesteal + ball multiplication). This triple-lifesteal setup provides: (1) constant healing from Soul Sucker phase-through, (2) burst healing from Vampire Lord bleed consumption, (3) scaling healing as Mosquito King multiplies balls. With this combination, you can facetank 15-20 enemies simultaneously while healing faster than they damage you. Soul Sucker's 1.7x multiplier is intentionally moderate—higher damage would risk killing enemies too quickly, reducing available lifesteal targets. The evolution is balanced around sustained combat rather than burst, making it ideal for "immortal tank" builds where survival duration matters more than kill speed. Against wave 20+ content, Soul Sucker enables indefinite survival: as enemy count approaches 30-40 simultaneously, your healing scales proportionally (40 enemies × 10 balls × 1-2 HP per hit = 400-800 HP healed per second), effectively making you unkillable as long as enemy density remains high. The strategy shifts from "kill enemies before they kill you" to "heal through all damage while gradually clearing waves"—a fundamentally different playstyle that Soul Sucker uniquely enables.
