Furnace

A furnace is a dungeon feature that appears in SpliceHack. At a furnace, you can combine items to create other items. You can also imbue monster corpses and tins into weapons and armor.

Generation

There is a guaranteed furnace on the topmost level of Sokoban.

Effects

Quaffing

Quaffing from a furnace kills you; the furnace contains lava.

Sitting

Sitting on a furnace deals fire damage to you.

Dipping

Dipping anything into a furnace has a ¹⁄₃₀ chance of blowing up the furnace. Dipping potions or scrolls into a furnace destroys them. If you #dip an item that can survive the lava damage into a furnace, such as a metallic weapon, there is a 130 chance the item becomes blessed, and a 130 chance the item becomes erodeproofed.

Imbuing

At the furnace, type #forge or press Alt Shift F. Use a weapon or armor as the first input item, then select a monster corpse, tin, figurine, or mask as the second item.

• Imbued weapons deal bonus damage dependant on the attack (ADTYPE) of the monster that was imbued. For example, a long sword imbued with blue dragon essence will shock enemies. This bonus damage is generally 1d6 of whatever the monster's first attack is.
• When polymorphing while wearing imbued body armor, you will polymorph into the monster type that armor is imbued with. This includes normally non-polymorphable monsters.
  • As of Spl-R-1.1.0, polymorphing into certain non-polymorphable monsters could be a bad idea, as there is sometimes insufficient game logic for your new form. For instance, if you become Medusa, the game will crash, because players can't normally possess a petrifying gaze. Becoming a watch captain is fine, however.
• You cannot imbue weapons with cockatrice or Rider essence, but everything else is fair game!
• After imbuing an item, there is a 50% chance the furnace is used up.
