Template:BossInfobox is a redirect to Template:NPCInfobox — calling

is identical to calling

and takes the same parameters. It builds the boss/NPC card (render + bossbar, health, fame, restrictions, full loot tables and tier-point requirements) and runs on Module:Infobox. Prefer writing

directly; the documentation below is the same as that template's.
The Forsaken

Breakdown
Most fields are plain text. The loot, dungeon-drop, title and fragment fields use a small
;-and-,mini-syntax — see the patterns at the bottom.title — boss name. Add a subtitle after a semicolon:
title=Name;Subtitle(subtitle renders smaller). Optional subtitle.image — the render plus (optionally) the bossbar image, as
Render;Bossbar. With the new naming that isBoss-3D<Name>.png;Bossbar-<Name>, e.g.Boss-3DKurvaros.png;Bossbar-Kurvaros. The first part is shown at 300px; the second (no extension needed — ".png" is appended) is shown wide above it. For non-boss NPCs use the matching render prefix: Mob-3D<Name>.png, Pet-3D<Name>.png, Mount-3D<Name>.png. If omitted, the site logo is used.SpecialInfo — free-text special note shown at the top with no label. Optional.
Health — boss HP (labelled "HP"). Fame — Fame Given. Glory — Glory Given. Biome — optional; mainly for world bosses. Tiered — the range of tiered drops, e.g.
7-11(labelled "Available Tiered Drops").Attack — attack-pattern description (no label). Optional.
Class-restriction fields (optional): CWeapon, CArmour, CAbilities — weapon / armour / ability class restrictions.
Loot fields — one per rarity, each a comma-separated list of items: Unholy, Voidbound, Bloodshot, Royal, Gilded, Irradiated (plus event pouches Halloween, Christmas, Valentine, Companion, Rune). Each item is written as four
;-separated parts:
DirectedPage;ItemName;File.png;PercentValuewhere DirectedPage is the page the link points to, ItemName is the displayed name, File.png is the sprite filename (just the name — not a [[File:…]] link), and PercentValue is the drop chance as a bare number (no % sign). Add more items in the same rarity by separating with a comma:
Page;Name;File.png;Pct,Page2;Name2;File2.png;Pct2Frag — fragment drops, written
Rarity;PercentValue(Rarity ∈ Bloodshot, Royal, Gilded, Irradiated), e.g.Frag=Bloodshot;25.DungeonDrop — dungeon(s) this boss can drop, each as
DirectedPage;File.png, comma-separated for multiple (labelled "Dungeon Dropped").Required — Required Tier Points to enter/challenge. Solo — Recommended Solo Tier Points.
