Summoners War: Sky Fever Nat 5 Selector Priority Guide

Select Teshar (Wind Phoenix) from the Sky Fever Nat 5 selector if your account cannot reliably clear Giant's Keep Abyss Hard in under 45 seconds. Accelerating rune acquisition provides the highest return on investment for early and mid-game accounts. If your Cairos Dungeon farming teams are already running efficiently, choose monsters with irreplaceable mechanics that cannot be replicated by alternative units: Tiana for guaranteed buff removal or Leo for absolute speed control.

Early PvE Priority: Teshar

Rune farming dictates all account progression in Summoners War. Giant's Keep supplies foundational Swift, Despair, and Blade sets required across both PvE milestones and competitive PvP.

Teshar enables high-speed clearing through his third skill, Tempest. When built on Fatal or Rage sets with high Attack, Critical Rate, and Critical Damage, Tempest clears standard trash waves in a single hit. Because Tempest's cooldown automatically resets whenever an enemy dies from the attack, Teshar can clear consecutive waves without delay when paired with an attack-power buffer like Galleon or Wind Homunculus.

While Teshar has limited utility in World Arena (RTA) and high-tier Arena defense, the sheer volume of high-quality runes generated by an optimized sub-minute Giant's team outweighs delayed PvP investment for a developing account.

Irreplaceable PvP Mechanics: Tiana and Leo

Accounts with established Cairos speed teams should bypass standard damage dealers in favor of unique passive and active utility.

Tiana (Wind Polar Queen)

Tiana provides the only completely irresistible dispel in the game. Her third skill, Wind of Change, removes all harmful and beneficial effects from both allies and enemies, then boosts ally attack bars by 30 percent.

Because this skill ignores the standard 15 percent base resistance check, it guarantees that opposing Will runes and Shield buffs are stripped before your defense breakers and damage dealers take their turns. Tiana is the premier enabler for reliable turn-one Arena cleave teams and Guild Siege offenses.

Leo (Wind Dragon Knight)

Leo alters turn order mechanics through his passive skill, Eye of the Storm. The passive forces all monsters on the battlefield to match Leo's combat speed, while granting Leo the first turn at the start of battle.

Leo completely neutralizes opponents who rely on superior Swift rune speed to take turn one. By capping the battlefield speed, Leo allows you to rune allied damage dealers and bruisers with zero Speed investment, redistributing those substat rolls into HP, Defense, Attack, and Critical Damage. He also provides consistent counterplay against high-speed Arena defenses and specific Tartarus' Labyrinth stages.

Niche Progression and Siege Scaling: Bolverk

Bolverk (Water Lightning Emperor) provides an answer to high-stat PvE bosses and heavily fortified guild defense teams.

• Mechanic: Bolverk acquires Knowledge stacks whenever any monster on the field gains a buff. Upon reaching five stacks, his third skill, Magic Power Rules, drains up to 50 percent of an enemy's maximum HP while healing his allies for the same amount.
• Investment Value: Because this HP reduction does not scale off Attack, Defense Break, or Critical Damage, Bolverk requires minimal offensive rune quality to operate. He bypasses standard damage mitigation, making him exceptionally effective in Trial of Ascension (ToA) Hell, Tartarus' Labyrinth hard modes, and Guild Siege offense.

Alternative Flex Options and Cautions

If your farming core is established and you already possess primary strip and speed-control tools, consider these functional alternatives:

• Woosa (Water Pioneer): Provides a three-turn Immunity and Shield buff alongside sustained healing. His high base speed makes him an accessible defensive stabilizer for Guild content, Labyrinth, and Arena defense.
• Verad (Water Dragon): Offers dual area-of-effect crowd control with complete attack bar reduction and freeze debuffs for ToA and Labyrinth. However, accessible free-to-play options like Tyron (Water Sylph) fill a similar role, lowering Verad's absolute selector priority.
• Rica (Fire Occult Girl): Applies three-turn continuous damage and slow debuffs for attrition-based ToA Hard stages and Siege offense.
• Units to Avoid Early: High-tempo RTA specialists such as Miles, Oliver, Masha, or Moore should be avoided by newer accounts. These units demand high-tier Violent, Swift, and Will rune sets with precise speed tuning to be effective.

Selection Decision Order

Evaluate your account in the following order before confirming your summon:

1. Check Giant's Keep speed: If you do not have a consistent, sub-minute Giant's Keep Abyss Hard team, select Teshar.
2. Evaluate buff removal: If your Cairos farming is secure but your Arena offense fails against Will runes, select Tiana.
3. Assess anti-speed options: If you lack the rune depth to outspeed opposing teams in PvP or struggle against fast guild defenses, select Leo.
4. Address end-game boss content: If progression is stalled by stat-inflated bosses in ToA Hell or Labyrinth, select Bolverk.
