As a set piece, if you 6 slot panaceas into a click like dull pain, you'll always get the set bonuses. The PvE for PvE, and the PvE+PvP in PvP.
 
	The proc will only fire off when you click dullpain. So it's better to stick it in an always on passive power like health or physical perfection.
 
	 
 
	The Preventative Medicine +absorb proc, however, works regardless of whether its in a passive or click power.
 
	 
 
	For my take on click heals, I just 3slot three different heal/absorb/recharge IOs and call it a day. Probably not optimal but it saves slots for other powers.
