Strategy & Tips

Required for Black Hole evolution. Good standalone evolution with strong area damage. Opens path to S-tier evolution.

Why Sun is Top-Tier

🟢 **VERIFIED MECHANICS:** Sun blinds all enemies within your field of view while applying 1 stack of burn every second (maximum 5 stacks), with each stack dealing 6-12 damage per second for 6 seconds (SOURCE: Steam Community Guide ID: 3587888441). Unlike on-hit evolutions, Sun's effects are continuous and passive—simply having the Sun ball active creates a persistent damage-over-time aura combined with map-wide crowd control through blindness. ⚠️ **TIER RATING & BLACK HOLE PATH:** Sun's tier rating varies significantly by source. Our database rates it A-tier as a standalone evolution, while PCGamesN's tier list rates it S-tier, likely due to Sun being the prerequisite for Black Hole (Sun + Dark = Black Hole, one of the strongest S-tier evolutions). The S-tier rating reflects Sun's dual value: strong standalone performance plus mandatory gateway to Black Hole. Players who plan to create Black Hole must create Sun first, making it a strategic necessity beyond its base power. 🟢 **SUSTAINED DOT SCALING:** The 1 burn stack per second mechanic means Sun reaches maximum damage (5 stacks × 12 max damage = 60 DPS) after just 5 seconds of uptime. Each burn stack lasts 6 seconds, creating overlapping damage windows where enemies take sustained burn damage as long as they remain in proximity. With 5 stacks active, enemies sustain 30-60 damage per second continuously—comparable to many high-damage evolutions but with the added benefit of map-wide blind for crowd control. 🟡 **FIELD OF VIEW COVERAGE:** The 'field of view' blind effect means Sun affects every enemy visible on your screen simultaneously, making it one of the few evolutions with true map-wide impact. This scales exceptionally well in late-game dense wave scenarios where 15-30 enemies are visible simultaneously—all blinded and burning from a single passive effect.

Strategic Tips & Synergies

💡

🟢 Verified mechanic: 1 burn stack per second (max 5 stacks) means Sun reaches full damage potential (30-60 DPS) in just 5 seconds—position to maintain enemy proximity for sustained burn accumulation.

💡

🟡 General strategy: The 1.8x damage multiplier scales with fire damage modifiers—prioritize fire damage upgrades to boost both the burn DoT and any base fire damage from the Burn ball component.

💡

🟡 General strategy: Sun's blind effect disrupts enemy movement and attack patterns—pair with area-denial evolutions like Sandstorm or Magma to trap blinded enemies in damage zones they can't navigate effectively.

💡

🟡 General strategy: The 6-second burn duration with 1-second application creates overlapping stacks—enemies that stay in range for 11+ seconds sustain continuous 30-60 DPS as old stacks expire and new ones apply.

💡

🟡 General strategy: Sun's field-of-view blind affects ALL visible enemies simultaneously—in dense late-game waves (20-30 enemies), this provides map-wide crowd control more valuable than the burn damage alone.

💡

🟡 General strategy: If planning Black Hole, create Sun early (wave 5-8) even if it's not your primary evolution—Black Hole's 3.5x multiplier and instant-kill mechanic make the Sun investment worthwhile purely as a gateway evolution.

💡

🟡 General strategy: Sun synergizes with positioning-based characters—movement speed boosts allow you to kite enemies while maintaining field-of-view blind coverage, maximizing burn stack uptime on pursuing enemies.

Best Character Pairings

These characters create exceptional synergies with Sun:

Iron Fool (A-Tier Pairing): Iron Fool's Burn starting ball provides instant access to half the fusion requirement, and the defensive passive enables sustained close-range positioning—critical for maintaining Sun's burn stack application on enemies. The tank playstyle keeps enemies in burn range longer.

Lantern Knight (S-Tier Pairing): Lantern Knight's fire damage passive stacks multiplicatively with Sun's burn DoT, increasing the 6-12 damage per stack by 25-30%. This synergy transforms Sun from 30-60 DPS baseline to 37-78 DPS, significantly boosting its sustained damage output throughout all game phases.

The Pitling (A-Tier Pairing): The Pitling's XP boost passive accelerates early Sun acquisition (character level 5-6 vs 7-9), which is critical if planning the Black Hole path. Earlier Sun creation means earlier opportunity to acquire Dark for the Black Hole fusion, potentially enabling Black Hole by wave 12-13 instead of wave 17-18.

Common Mistakes to Avoid

⚠️

Ignoring Black Hole path: Sun is rated S-tier by multiple guides specifically because it's the gateway to Black Hole (Sun + Dark). Players who create Sun without considering the Black Hole upgrade miss the evolution's primary strategic value—Sun's standalone performance is strong, but its role as a Black Hole prerequisite is exceptional.

⚠️

Creating Sun too late: If planning Black Hole, creating Sun after wave 12+ delays or prevents Black Hole acquisition since you then need to find and level Dark before late-game waves. Sun should be created by wave 8 maximum to ensure sufficient time for the Black Hole transition.

⚠️

Misunderstanding burn stacking: Sun applies 1 stack per second automatically (not on-hit)—attack speed and hit rate provide zero value for Sun's mechanics. Prioritize damage modifiers (fire damage, DoT amplification) over attack speed when running Sun.

⚠️

Undervaluing the blind effect: Many players focus solely on Sun's 30-60 DPS burn damage and ignore the map-wide blind. In dense wave scenarios (15-30 visible enemies), blinding all enemies simultaneously provides massive defensive value by disrupting enemy movement and attacks—often more valuable than the damage itself.

⚠️

Poor positioning for field-of-view: Sun's blind only affects enemies within your field of view—playing in the center of the map maximizes visible enemy count (360-degree coverage), while corner play reduces effectiveness to 90-180-degree coverage. Central positioning ensures Sun affects maximum enemies.

Expert-Level Optimization

⚠️ Advanced strategy combining 🟢 verified mechanics + 🟡 general principles: Sun's 1 burn stack per second mechanic (max 5, 6-second duration, 6-12 damage per stack per second) creates a 5-second ramp to maximum DPS (30-60 damage per second sustained). The optimal Sun strategy depends on your build path: (1) Black Hole Path—create Sun early (wave 5-8) as a mandatory stepping stone, then transition to Black Hole (Sun + Dark) by wave 12-15 for the 3.5x multiplier instant-kill upgrade; or (2) Standalone Path—maximize Sun's sustained DoT by pairing with fire damage upgrades and positioning for maximum field-of-view coverage. For Black Hole Path players, Sun's standalone power is secondary to its gateway role—even if Sun provides moderate DPS, the ability to create Black Hole justifies the evolution slot. For Standalone Path players, Sun excels in extended wave scenarios where the 6-second burn duration and continuous 1-stack-per-second application create overlapping DoT windows—enemies that remain in proximity for 10+ seconds sustain uninterrupted 30-60 DPS as old stacks expire and new ones apply. The map-wide blind effect scales exceptionally in late-game dense waves (20-30 visible enemies)—all enemies blinded simultaneously provides crowd control value exceeding the burn damage. Pair Sun with area-denial evolutions (Sandstorm, Magma) to trap blinded enemies in damage zones they can't navigate effectively. Central map positioning maximizes Sun's field-of-view coverage (360-degree visibility) versus corner play (90-180 degrees), ensuring the blind affects maximum enemy count per second. For fire-focused builds (Lantern Knight, fire damage stacking), Sun's 6-12 damage per stack scales to 8-15+ with modifiers, pushing sustained DPS from 30-60 baseline to 40-75+, making it competitive with dedicated damage evolutions while retaining the blind utility.
