Rend Disables Staggering Palm Buff

Using the wyvern skill rend will remove shockwaves from the buff that staggering palm grants.

Reverting back to attacks in human form does not return the shockwaves. The buff timer is still present, and can be extended by performing more heavy stuns; however, no shockwaves will be produced.

The only way to get shockwaves again after using rend is to allow the staggering palm buff to completely expire, and then acquire a fresh buff.
