This is a list of hidden, lesser known, or possibly glitched mechanics for classes, skills, and attributes or in general based on the contributions in this thread and other sources.

If you’d like to contribute please be as informative as necessary (which class, skill, etc.). I will update the list with your provided information and leave a link to your post at the end of each listed. I’ll like your reply once the edit is complete both for myself (to note that I got to it) and as thanks. If you want to correct or elaborate upon something that’d be very much appreciated!

General

Many skills’ attributes have secondary effects such as increasing a skill’s cooldown or SP cost. You can find each in the tosbase Attribute Database.

When you enter rest mode for the first time in a zone, it instantly recovers HP, SP, and stamina. It also triggers a timed interval which after each interval repeats the recovery if you’re in rest mode. This timed interval continues when you exit rest mode, so you can enter and instantly exit rest mode after each interval for passive recovery, even while in combat.
