|Chainbound Skillchain Properties|
- While Chainbound status is in effect, any weaponskill with a level 1 skillchain element used by the player or party member will create a skillchain. Weaponskills with only level 2 or 3 skillchain elements (such as Shark Bite/Fragmentation) will not coordinate with Chainbound
- Important Note: For purposes of skillchain calculation, only the highest priority level 1 skillchain element of the closing weaponskill is considered. All other level 2, level 3, and secondary skillchain elements are completely ignored.
- Please also note that due to the priority and properties of the skillchain elements while the target mob is Chainbound, 3 of the 8 active skillchain elements are never used. Thus, it is impossible to create Impaction, Reverberation, Gravitation, or Distortion skillchains.
