Slayer Legend Companion Build and Stat Setup Guide

To build companions effectively in Slayer Legend, configure passive abilities and promotional dice stats for offensive multipliers—primarily Extra Attack % and Critical Damage %—while leveling equipment and promotions evenly across your entire unlocked roster.

Companions transfer a portion of their stats and multipliers directly to your main Slayer. Because companions cannot die in standard encounters, survivability stats provide zero practical value.

Stat Priority and Reroll Order

When rolling companion passive lines and dice promotion slots, prioritize offensive stats over defensive utility:

Extra Attack %: The top priority. This scales directly with your Slayer's total attack rating, delivering the largest overall damage increase per slot.
Critical Damage %: Essential for amplifying damage spikes, scaling your burst rotations once your main Slayer's critical strike rate is established.
Death Strike Damage %: Valuable once your main Slayer consistently triggers Death Strike chance, accelerating clears against high-health elite monsters.
Accuracy: Use only when pushing stages where boss evasion causes your attacks to miss. Once your hit rate is sufficient, reroll extra Accuracy into raw damage.
HP and Defense: Avoid locking or keeping these rolls. Defensive stats provide virtually no progression value on companion boards.

When rerolling, lock high-tier Extra Attack % and Critical Damage % lines. Locking multiple lines increases reroll costs, but retaining defensive rolls dilutes your account's combat efficiency.

Companion Roles and Promotion Strategy

Each companion provides distinct passive benefits and active skills. Distribute promotion points across all unlocked companions rather than hyper-investing into one unit, as promotion point costs increase exponentially at higher tiers.

Companion	Primary Focus	Best Use Case
Luna	Spell burst and cooldown acceleration	High-defense stage bosses and promotion trials
Ellie	Rapid ranged damage and attack speed buffs	Group mob farming and resource dungeons
Zeke	Melee burst and stun utility	Interrupting boss attack patterns and elite stages
Miho	Buff amplification and sustained damage	Extended boss encounters and high-wave stage pushing

Bringing all unlocked companions to balanced promotion tiers generates more total stats for your Slayer than maxing out a single companion while neglecting the rest.

Equipment and Advancement Checklist

Follow these steps to upgrade companion gear efficiently:

Equip Highest Rarity Gear: Always assign your highest rarity weapons to your active companions to secure the highest base multipliers.
Level Companion Weapons Evenly: Distribute weapon enhancement stones across your full team. Leveling multiple weapons to tier 50 costs substantially less than pushing a single weapon from tier 80 to 100, while providing a higher total Attack yield.
Target Awakening Milestones: Awaken companion weapons to unlock secondary trait lines, then roll those bonus slots for Extra Attack %.
Synchronize Advancements: Unlock baseline advancement passives on newly acquired companions before paying the higher material costs for advanced ranks on starting units.

Presets: Boss Encounters vs. Stage Pushing

Maintain dedicated companion presets to match the demands of single-target timers and multi-target waves.

Boss Preset

Boss fights require maximum damage within a 30- to 60-second window before enrage triggers.

Focus companion stats strictly on Extra Attack %, Critical Damage %, and Death Strike Damage %.
Equip single-target burst skills and defense-shredding debuffs to maximize damage during your Slayer's primary damage windows.

Stage Pushing Preset

Standard adventure stages feature dense enemy swarms that can body-block your Slayer if clear speeds stall.

Focus companion abilities on area-of-effect damage and cooldown reduction.
Use multi-target skills to clear regular mobs quickly, keeping your Slayer moving cleanly through waves.
