Kunark Clickies
 

I was in a group last night and a warrior told me he was unable to use his str buff from cobalt boots on anyone else as it was self only. I know that on my rogue, I can click all my buffs onto other people. Is this limited to certain pieces/certain spells? Or are they all pretty much clickable onto others? Seems strange it would be limited like that. Thanks!

All class clickys are different. Read wiki to see if self only or not /nod

if the spell itself can be targeted (is not target=self or pbae) then it can be targeted via the clicky item as well, if the spell is self-only then the clicky will be self-only

Cobalt Boots use Strength of the Kunzar which is 'self' target
Mrylokar Vambraces use Strength of Earth which is 'single' target
