Hello dragonriders!

A couple updates coming in an upcoming build that warranted pointing out:

The text in the tooltips for dragon isle drakes have been corrected to state more accurate values. NOTE: Actual maximum speed values have not changed from the previous build.

For those that need or want a quieter full screen effect for max speed, the accessibility option “Alternate Full Screen Effects” now lessens the dragonriding max speed effect. Please try this out and share your feedback.

Surge Forward’s effectiveness has been increased by 20%.
