Contribution is another resource that is based on how much you have helped a certain region. It is used mainly to invest in nodes, purchase housing or rent items. 

Earning Contribution Points

You can earn contribution points by completing quests, discovering new regions, or exchanging certain items for more contribution points. Contribution works similarly to EXP, in that you need to level up the contribution meter before you are rewarded with more. Much like character levels, each increase in contribution becomes more difficult to achieve. 

Spending Contribution Points

Contribution Points can be spent on Nodes, Houses, or renting special items. However you choose to spend your contribution points is up to you. When using contribution points, remember that they can be refunded. By returning a rented item, or withdrawing from a connected node, you can earn any contribution points back.
