# Missions
Evoskulls and Pets can be sent on a Mission in order to earn [$SLS](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/souls-usdsls) (Souls).
### The Slot System
Each wallet starts with 3 slots for Pets and 3 for EvoSkulls. This means that there are separate slots for Pets (Seperate slots for each season as well) and EvoSkulls. These slots are used to choose which pet/EvoSkull to send on a mission. When a pet is sent on a mission, that slot becomes unavailable. \
The only limit is the amount of slots you have. You can unlock more slots for your wallet by paying [$GRVE](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/grave-usdgrve). (Up to a maximum of 10 slots per wallet! These are permanently unlocked). \
The [$GRVE](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/grave-usdgrve) used for this unlock will be burned.
**Unlock price per extra slot:**
* 4th slot costs 30 [$GRVE](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/grave-usdgrve)
* 5th slot costs 60 [$GRVE](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/grave-usdgrve)
* 6th slot costs 120 [$GRVE](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/grave-usdgrve)
* 7th slot costs 240 [$GRVE](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/grave-usdgrve)
* 8th slot costs 480 [$GRVE](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/grave-usdgrve)
* 9th slot costs 960 [$GRVE](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/grave-usdgrve)
* 10th slot costs 1920 [$GRVE](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/grave-usdgrve)
The amount of [$SLS](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/souls-usdsls) earned will be based on your Pet/Evo’s level. The higher the level, the higher the rewards.
* Each mission consumes 1 stamina.
* Stamina regenerates at a rate of roughly 1 every 4 hours (Block based).
* Max 10 daily missions per Pet/EvoSkull.
* Multiple missions can be done within the same transaction (Up to 10)
* Mission duration is 2 hours for every mission.
* You can send multiple pets/EvoSkulls from the same collections, within the same transactions up to the amount of available slots.

Once your Pets/Evoskulls have finished their missions, you have to "Return" them. The rewarded [$SLS](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/souls-usdsls) gets accumulated in the mission section, and can be claimed from there. This is in order to reduce gas fees, so that users can claim the [$SLS](https://croskulls-organization.gitbook.io/croskull/erc20-tokens/souls-usdsls) when they wish to do so.
### Malus debuff
When returning from missions, the Pets/EvoSkulls sometimes get afflicted by a Malus debuff. \
There is a *10%* chance for this to happen after each mission. If you are doing multiple missions within the same transaction, the chance to be afflicted with a malus effect increases. \
(Chance of Malus = Number of missions within the same transaction x *10%*. This means that 2 missions, would give a *20%* chance of malus, 3 would give *30%* and so on). \
If your Pet/EvoSkull returns with a Malus debuff, it will be afflicted by one of the following effects:
* Hunger (Max stamina gets reduced)
* Freezing (Locks the Evo’s/Pet’s usability)
* Sadness (Power gets reduced, which is the total amount of stat points of Pet/EvoSkull).
The Malus effects can only be removed if the specific item required to remove it is used on the pet/EvoSkull affected. This is done from the [Tavern](https://croskulls-organization.gitbook.io/croskull/ecosystem/season/tavern) section of our [Dapp](https://app.croskull.com/#/). There can be more than one Malus debuff active at the same time. \
The Pet/EvoSkull can continue doing [missions](https://croskulls-organization.gitbook.io/croskull/ecosystem/missions) with the Hunger and Sadness Malus, but the Freezing Malus makes it unable to continue missions until cured or it goes away by itself (roughly 24 hours to defrost).
{% hint style="info" %}
Items to remove the effects of Malus can be purchased in the [Merchant](https://croskulls-organization.gitbook.io/croskull/ecosystem/merchant) section of [Dapp](https://app.croskull.com/#/), the items can be found inside the *mystery boxes*.
