Pickups

Pickups are items other than Weapons, Skills, Runes and Amulets which can be found during gameplay. Pickups can be collected using the Interact key while the player is close enough to do so.

There are two major types of pickups: gems and food.

Gems
Gems are a type of pickup which grants a significant amount of gold when collected.

The table below lists all gems in order from least valuable to most valuable. Generally, gems become more valuable when they appear in harder zones, and their values seem to increase multiplicatively by ~18.9% (~2^0.25) with each difficulty increment.

Food
Food pickups regenerate a fixed amount of health when eaten. Two types of food exist, Carrots and Chicken.

Carrots
By far the more common of the two types of food, Carrots restore approximately 25% of the expected max health for a given zone. They can be randomly looted from enemies and secrets or found at the end of a branch or inside of a food shop.

Chicken
Chicken is much more effective at healing the player, granting 4x the healing of a Carrot (or approximately 100% of the expected max health for a given zone). However, Chicken can only be found inside of a food shop.

Crypt Key
"'Open the gates of Hell...'"Only found in the Graveyard in one of the minor tombs, the Crypt Key is required to open the door leading down into the underground portion of the level. Unlike other pickups, the Crypt Key adds a key currency when picked up which can be seen above the player's carried cells (it disappears once the locked door has been opened).
