Infinite Magicraid: How to Choose and Upgrade Spirit Beasts

To get the most value from Spirit Beasts in Infinite Magicraid, choose a beast whose passive aura matches your primary damage dealer's win condition, then concentrate your upgrade materials on that single beast before building secondary options. A Spirit Beast occupies an independent squad slot, providing unconditional team-wide passive stat bonuses to all five heroes alongside an automated active skill that fires during combat.

Because upgrade resources are limited, fully upgrading one primary offensive beast generates far more progression impact than splitting investments across several unmaxed beasts.

Spirit Beast Archetypes and Squad Synergies

Deploy a beast that reinforces the specific scaling needs of your squad. Direct damage carries require raw offensive stats, while damage-over-time (DoT) lineups prioritize debuff application and turn survival.

Beast Archetype	Core Aura Bonuses	Ideal Squad Synergy	Best Game Modes
Offensive Burst	Attack %, Crit Rate %, Crit DMG	Direct Damage, Speed Cleave	Fast Dungeon Farming, Brave Trial, Arena Offense
DoT & Control	Effect Hit %, Attack %, Speed	HP Burn, Bleed, Poison	Guild Boss, High-Stage Dungeons, Tower of Mark
Sustain & Guard	HP %, Defense %, Effect RES	Shielding, Stall, Counter	Difficult Campaign Bosses, Arena Defense

If your team runs HP Burn or Poison setups, prioritize beasts granting Effect Hit and survivability over Critical Rate. DoT effects rely on consistent application and surviving enough round cycles for damage ticks to accumulate on the enemy.

Recommended Upgrade Sequence

Upgrade currency should remain focused on a single carry beast until its primary stat lines are maximized. Follow this priority order to clear progression bottlenecks efficiently:

Unlock the Base Beast: Obtain your chosen core beast via summoning pools, selector chests, or event milestones to activate baseline passive auras across your whole formation.
Prioritize Offensive Aura Nodes: Invest early materials into Attack and Critical stats first, as universal damage boosts provide immediate clear consistency in resource farming stages.
Enhance the Active Skill: Level up the beast's active ability to raise its damage multipliers and unlock secondary utility, such as Defense Down debuffs.
Complete Defensive Nodes: Finish remaining HP and Defense aura nodes once your core damage output easily clears your current stage requirements.

Deployment Strategy: PvE vs. Arena

Adjust your deployment choices based on whether you face multi-wave dungeon encounters or competitive player defenses:

Campaign and Dungeons: Run an offensive beast with high burst or area-of-effect active abilities. The active strike softens enemy waves, allowing your main carry to secure reset kills before opponents cycle dangerous ultimate skills.
Arena Offense: Equip an offensive beast with Speed and Attack bonuses to ensure your team takes the first turn and punches through enemy shields during a speed-cleave opener.
Arena Defense: Switch to a beast emphasizing HP and Effect Resistance. Extra bulk and resistance protect support units from first-turn crowd control, giving counter-attack and sustain mechanics time to stabilize.

Investment Pitfalls to Avoid

Prioritizing active animations over passive auras: A beast's active skill triggers periodically, but its passive aura applies continuously. Equipping a beast with a strong active strike but mismatched aura stats—such as defense boosts on a fragile speed-cleave team—drastically limits your squad's overall damage output.
Neglecting frontline durability: Spirit Beasts charge their active skill through allied actions and elapsed turns. If your support heroes fall early in combat, your beast will not survive long enough to trigger its active ability. Maintain sufficient team defense so your squad lasts until the beast can fire.
