Factory



The Factory is the optional level of The Rift.

You can access it by unlocking the door at the second level of the Rift with a Treasure Key. In this level, you can gather one of the four Rune Orbs (this one provides 2 LCK) in the game.

Spikes


Touching this trap from above deals instant death to the player or creature, with some exceptions.

Countermeasures

Simply walking through spikes causes no harm whatsoever.

Spike Protection gear will permanently destroy wooden spikes when the player would otherwise be impaled on them.

The Featherfall status effect will let you fall through spikes harmlessly unless you are pressing Down to fall faster. It can be obtained from drinking a Potion of Featherfall, wearing Featherfall gear, or holding on to a Chicken.

Slowly sliding down walls using the Rogue's Acrobatics skill or Climb Walls gear will let you fall through spikes harmlessly.

Bad ideas

Some things do not offer spike protection, even though it seems like they might: Special interactions
 * The Wildling's Bear Stomp ability.

The Goblin King destroys spikes as if he wore Spike Protection gear. Other bosses are entirely immune. Fox Thieves are also immune.

Acid
Found in The Factory. Acid deals a 15 damage every few seconds, which is likely to stun the player, keeping them trapped in the pool and forcing them to take further damage.

The damage dealt in this way is a unique type of elemental damage. No source of acid resistance currently exists, not even from the +1 all resistances stat boost.

Volt Traps
Found in The Factory. Volt Traps are harmless until a bolt of electricity (originating from a Mechanical Spider or from the Rust Fiend) comes into contact with them. In those cases, they create a high, powerful and short-lasting pillar of electricity.
