Pom of Power

Pom of Power (short for Pomegranate of Power) is an Artifact that increases the level of one of your boons on acquisition. It can be recieved as a room clear reward or purchased from Charon for 100.

When received as a reward from an Infernal Gate, Elite Temple of Styx Wing, or when purchased for 300 from Charon's Styx shop, it will increase the boon's level by two levels. Applying multiple Poms to the same boon will be less effective each time. The exact effects of a Pom differ between boons.

If you don't have any boons, or only have boons that can't be leveled up (such as Poseidon's Huge Catch), you will instead get 115 as Spare Wealth.

Pom Slice
A Pom Slice is similar to a Pom of Power, in that it increases the level of one of your boons on acquisition. The primary difference is that it levels up a boon at random, rather than giving up to three choices. Pom Slices can only be purchased from Charon's shop for 50.

Leveling Mechanics
From level 1 to 6, for most boons, strength increases with diminishing intensity, i.e. there is a more significant boost between level 1 to 2 than 2 to 3, etc. With some approximation, the rate between level 1 and 6 can be expressed as divided by 2 every 2 level with a starting value set. For example Poseidon's Special level 2 to 6 is +28%, +20%, +14%, +10%, +7%. Past level 6, for most boons, strength will continue to increase at a small linear value; for example, Aphrodite's Strike level 5 to 6 and upper will always increase by 5% per level. Some exceptions exist, however, such as Ares's Doom-inflicting boons, that will continue to decrease until it will add 1 per level only.

Boons that have low base value (Such as Dionysus's Hangover damage, Artemis's Pressure Points, or Demeter's Glacial Glare) will increase linearly by 1 with each level from the start. A select few, such as Athena's Aid, increases less than 1 per level.

The strength increase from a level is independent of a boon's quality, and the level of a boon is preserved when its quality changes.

Increasing a boon's level also increases its value when being sold at a Pool of Purging.

Note

 * Pom of Power is a reference to the myth of Persephone, who was tricked by Hades into eating pomegranate seeds from the Underworld.
