Combine Element, Battle, and Weapon familiars into prime familiars - set star levels, preview the prime's skill, and save or share your build.

Familiar Builder

The Familiar Builder plans prime familiar combinations for Slayer Legend. A prime familiar forms from three base familiars, one from each category - an Element familiar (the Fire, Water, Wind, and Earth attribute boosters), a Battle familiar (combat abilities: Coup, Painting, Shaman, Pho), and a Weapon familiar (the damage-dealers: Me, Leone, Le, Mousse). Twelve base familiars, sixteen possible primes, and the exact trio determines which prime you get - which is precisely the kind of puzzle worth solving on paper first.

What you can do

Slot a familiar into each of the three category slots and the builder previews the resulting prime familiar live, including its skill, what the skill does, and its cooldown. Each slot has an adjustable star level (zero through ten), and stars matter: they step familiars through rarity tiers that raise stats and change appearance. Signed in with GitHub, you can save individual familiars at their star levels to your personal collection, then drag them straight from the collection into builds - and save the finished builds to your account. Builds share as short links and export or import as JSON files, with drafts auto-saving in your browser while you work.

Tips

• Work backwards. Decide which prime skill you want, then find the trio that produces it - the builder makes checking combinations free.
• Match your Element familiar to the element your build actually deals damage with; a mismatched booster is a wasted slot.
• Raise stars on your everyday trio before spreading investment across the whole roster.
