# Bonuses **Bonuses** are applied to a Kamigotchi either temporarily by consuming items or by unlocking new [Skills](/gameplay/kamigotchi/levels-and-skills.md). There are many types of Bonuses. \ \ Bonuses that contribute to **harvesting** are: * **Harvest Fertility Boost**: [Skills](/gameplay/kamigotchi/levels-and-skills.md) that increase your Harvest Fertility Boost improve the advantage a Kami gains from harvesting in type-aligned rooms. For instance, if you have a

S**crap-bodied** Kami harvesting in a

**Scrap room**, boosting Harvest Fertility will magnify the harvesting advantage your Kami receives by being in that room. Harvest Fertility also adds a smaller general bonus for

**Normal type** Kami, equal to 50% of other types. * **Harvest Intensity Boost**: The longer your Kami harvests without being fed or otherwise interrupted, the greater its rate of

**MUSU** accrual. Skills that boost your Harvest Intensity increase the rate at which this Intensity is gained. * **Harvest Bounty Boost**: Plain and simple, Harvest Bounty Boost is an overall percentage increase on the total rate at which your Kami harvests. Other Bonuses contribute to your Kami’s ability to

**liquidate** other Kami: * **Attack Threshold Ratio**: Much like Harvest Fertility magnifies type advantages for harvesting, increasing Attack Threshold Ratio enhances type advantages for liquidations. For example, a Kami with

**Scrap hands** has a type advantage against Kami with

**Insect bodies**, and can liquidate them at a higher HP threshold. Increasing the Attack Threshold Ratio magnifies this advantage even further. * **Attack Threshold Shift**: Skills that influence Attack Threshold Shift provide an overall percentage increase in the HP% at which your Kami can

**liquidate** another Kami. The higher your Attack Threshold Shift, the better your Kami’s ability to liquidate higher-health targets. * **Attack Spoils Ratio**: When your Kami liquidates another Kami, you will retain a portion of the

**MUSU** that had been gathered by your victim. Increasing the Attack Spoils Ratio increases the % retained. Another set of Bonuses increases your Kami’s ability to **defend** itself: * **Defense Threshold Ratio**: The defensive complement to Attack Threshold Ratio, the Defense Threshold Ratio magnifies type advantages for defending Kami. * **Defense Threshold Shift**: The defensive complement to the Attack Threshold Shift, the Defense Threshold Shift provides an overall percentage decrease in the HP% required for your Kami to be liquidated by an attacker. * **Defense Salvage Ratio**: When one of your Kami is liquidated, you will retain a small proportion of its

**MUSU** gathered. Increasing the Defense Salvage Ratio increases the retained proportion. A final three Bonuses impact your Kami more **broadly**: * **Resting Recovery Boost**:

**Harmony** normally determines the base rate that your Kami recovers HP while resting, and increasing Resting Recovery increases this rate further. * **Strain Boost**: Your Kami gradually loses HP while harvesting. Strain Boost reduces the rate at which that HP loss occurs. * **Cooldown Shift**: Improving your Kami’s Cooldown Shift reduces the cooldown period on actions, allowing you to take another action sooner.
