Item
Crystal is an in-game item that can be bought from a Shop or can be found in a Crate. Most Items modify the Stats of the player, and some of them provide additional effects.
Notes
In addition to the permanent +5% Attack Speed, Crystal also gives you +1% attack speed every second that you're able to not take damage. If you take damage, the bonus is lost and it starts counting again. The bonus is also lost at the end of each wave.
Self inflicted damage from for example 
Blood Donation or File:Sicky.png Sicky will reset the bonus.
