Skilltree

The skill tree consists completely out of items you can loot. Little "Gems" or similar things can be transplanted into your character and give him new abilities, new passives and new looks.

Visually, the character inserts the gemstones in his arm and the body reacts to it and changes. Comparable to the Skilltree Tattoo from Farcry3.

Everything can be combined and some classes have bigger impact on gameplay than others.
