The Bazaar Library Arsonist: Skill and Library Guide

What Does Library Arsonist Do?

The Bazaar Library Arsonist is a Legendary skill with no abilities in patch 20.1. For a Burn build, that means it provides no damage increase on its own. Its history explains why you might associate the name with a bonus to Medium Burn items.

The skill has a listed price of 40 gold and belongs to the Common and The Dragons collections. Its Legendary tier describes its rarity; there is no accompanying combat effect.

Evaluate your Burn damage using the effects on your active items and other skills. Library Arsonist contributes no additional Burn, cooldown reduction, or triggered attack in this version.

Why Older Descriptions Mention Second Degree Burns

Before patch 15.0, this skill was called Second Degree Burns. Its earlier effect increased the Burn on your Medium Burn items by 2/4/6/8, scaling across Bronze, Silver, Gold, and Diamond tiers.

Patch 15.0, released June 3, 2026, changed its name to Library Arsonist, moved its starting tier to Legendary, and removed that Burn bonus. Patch 17.0 added its association with The Dragons.

That distinction matters if you're following an older build description. A setup that counted on Second Degree Burns was using an actual damage modifier. Applying that same calculation to the current skill overstates your board's Burn.

Use the patch 20.1 behavior when evaluating the skill: the former Medium-item bonus belongs to its history.

Library Arsonist, Mak's Library, and Burning Library

Library is a separate large Mak item that starts at Gold tier. It changes the cooldowns of items on your board:

Effect	Gold Library	Diamond Library
Increase your Weapon cooldowns	1 second	1.5 seconds
Decrease your non-Weapon cooldowns	1 second	1.5 seconds
Purchase price	24 gold	48 gold

Count both sides of that cooldown trade before buying it. Compare the benefit to your non-Weapon items against the delay imposed on your Weapons.

When playing Mak, you can find Library at Pol, Goldie, Tok's Clocks, Kina, Jay Jay, Luxe, Barkun, Midsworth, and Valpak. Enchanted copies can also appear rarely at Knightshade, Hef, Chronos, Serafina, Freiya, and Cobweb.

Its selling price is 12 gold at Gold tier and 24 gold at Diamond tier. The Golden enchantment doubles its selling value. Keep that separate from the Gold item tier: Golden is an enchantment with its own effect.

A Fiery Library also applies 3 Burn whenever you use a non-Weapon item. That enchantment supplies a specific combat effect independently of Library Arsonist.

Other enchantments use that same non-Weapon activation trigger to produce different effects. Toxic Library applies 3 Poison, while Obsidian Library deals 30 Damage. These values are the same at Gold and Diamond tiers. Count the non-Weapon items you actually activate when comparing those effects with the Fiery version.

The defensive enchantments also trigger when you use a non-Weapon item. Shielded Library grants 30 Shield, and Restorative Library heals 30. Mossy Library grants 3 Regen with each qualifying activation; that Regen lasts until the end of the fight. Each of these enchantments retains the same listed effect amount across Gold and Diamond.

For control, Heavy Library Slows an enemy item for 1 second, while Icy Library Freezes an enemy item for 0.5 seconds. Turbo Library Hastes one of your items for 1 second. All three trigger from using a non-Weapon item, so their activation condition differs from effects that trigger only when Library itself is used.

Shiny Library adds 1 second to both its cooldown increase and cooldown decrease. Account for the larger Weapon penalty alongside the stronger non-Weapon reduction. Deadly Library gives your non-Weapon items +50% Crit Chance, while Radiant Library makes your non-Weapon items experience Freeze and Slow for half as long.

The Library encounter has another related name: Burning Library. Patch 20.0, released November 4, 2026, gave Burning Library its own artwork. Keep these names separate when reading your choices: Library Arsonist is the skill, Library is Mak's cooldown item, and Burning Library appears in the encounter's visual update.
