I started writing down what skills do. Some of the stuff is based on testing. This guide is by no means complete, feel free to add corrections in the comments.

The guide focuses more on the weapons' and skills' mechanic rather then on numerical values.

I tried to leave out damage numbers and cool down times as they are affected by the passive upgrades.

All the info was gathered on version B0.2.1.

Updated the guide according to B.0.2.2 changes.
