The Crowdfunded achievement is earned through sheer grit and skill in the arena. You’ll find plenty of arena tournaments throughout the main settlements of Calradia, and you’ll often be notified on the campaign map when a new tournament is about to begin, giving you time to travel there and take part. You may find competing in tournaments difficult at first, but they’re great fun and you will only improve with more practice. The more you level up your character while playing the regular campaign, the greater your chances of winning a tournament will be. Keep in mind that you can’t always choose which weapons you’ll be using in a tournament, so it’s a good idea to maintain a good balance of investing in melee and ranged weapons, rather than putting all of your points into one weapon in particular.
