Achievements
Each dragon has 4 primary abilities. Each of these abilities has it's own talent tree, with an Ultimate Talent at the top.
There are now Steam Achievements for getting each of these 36 Ultimate Talents.
Additionally, winning 50 games with any single dragon gives you a mastery achievement for that dragon!
