PixelSkills is a MMO plugin based around adding skills players can level up by doing tasks in the Pixelmon mod. Basically, its a Pixelmon MMO plugin. 17 Skills exist in the mod:

Archaeologist
Artificer
Barterer
Botanist
Breeder
Caregiver
Collector
Conqueror

Culinarian

Darwinist
Fisherman
Gladiator
Harvester
Looter
Photographer

Teacher

Trader

The plugin is highly configurable (and because of this, it needs to be configured at least a little bit before being used!) (I will likely at some point in time create basic template configurations for those who are lazy) There are 3 different rewarding modules inside the plugin:

Perks
Rewards
Level-Locked Rewards

Perks are rewards given to the player when as they do the tasks inside the skills. The perks are hard-coded into the plugin and cannot be changed (though, certain settings about them can be changed, or it can be toggled to use a custom perk instead of the default perk, which basically acts the same as a Reward) Rewards are rewards given to the player as they level up skills.

Rewards are configurable to give money, items, permissions, Pokemon, basically anything you can think of. Perks and Rewards have configurable chances to trigger when the code for them runs.

Level-Locked Rewards are essentially 100% guaranteed rewards to be given to the player when they hit the level that the reward is locked to. Its settings are the same as Rewards.
