Worn Effect Question

[Melandril]

I've managed to create an item and attach a proc to it, but although the Worn effect shows in the item description it does nothing. I've tried using, a created spell, a modified spell, a bard song and an illusion. I've tried setting the WornType to 2 (which everything else in PEQ DB is) and also 6 (on the hope that it meant Self here.)

I did once make it far enough with an HP buff that the client thought it had more HP, but the server did not accept that modification.

Help, please =)
