Active Abilities Tips:
-If you were like me and my friends, you assumed your abilities were constantly on a cool down timer. This is false. All skills are only cooled down via ability orbs,the blue lightning bolt. To see how many orbs you need to cool down a skill, mouse over the first icon of each ability in the ability tree. This gives a description of the ability as well as shows exactly how many cores it takes to cool down each skill.
-If an ability is active, and you pick up an orb, it will still count toward its cool down when the ability is done. If you have all abilities up, and you see some orbs on the ground, might as well pop a skill and get the cool down right away. Otherwise those orbs are wasted and your abilities just sit there. Which leads me to my last tip
-Use your abilities often. I can't confirm it yet, but it seems like the game will drop more cool down orbs, the more abilities you currently have in cool down. I tend to like to initialize medium to big encounters with abilities as often as possible. More often than not, I pop some abilities, kill a ton of shit, and by the end of the battle, there are enough cool down orbs to bring at least one ability back up.
