Scavenger

Scavenger is a skill in the Resource Tree of Luck. It has a maximum level of 6, and is considered one of the most valuable skills.

Each level of Scavenger increases the player's chance of getting lucky when breaking a barrel. Each component (or scrap) in a barrel has a chance to trigger the skill, resulting in extra items. The item amount is chosen randomly from a range, but there will always be at least 1 extra item. The random range is between 1 and the "maximum" value, which is ((5 * (5 (or 95) * scavenger level) / 100) + 5).

$$5 + ((5 * (5 * Scavenger Level)) / 100)$$

Alternative for Scrap:

$$5 + ((5 * (15 * Scavenger Level)) / 100)$$

When getting Lucky with Scavenger, the player will get a Luck XP bonus. The base random range is 48-112, which is then multiplied by the extra item amount gained. In the case of a maximum bonus of 7 (rounded from 6.5 because item amounts cannot have decimal points), and with a maximum base XP gain of 112, this would result in 784 XP (112 * 7). The same formula is true for Scrap, except the Scrap item amount has a 0.125x multiplier.

As with all skills, the chance to get lucky is affected by your Chance level and multiplier.

The maximum theoretical chance to get lucky is 99%, though this would require the player's Chance to be incredibly high.
