Need help with item usage

I am a tank and I have certain items that I would like to have used as often as possible and trying to figure out how to make that happen.

I have Orgozoa’s Paralytic Barb, a weapon I can use.

I have Chain of suffering that needs to target someone to use.

I would love to have both of these added to my macros in GSE. So can anyone help me figure these out?

Is there any way to make health-related macros? Would love to be able to have Healthstones and maybe light of protector to only be used at certain health percentages.

As for the percentage based no you can’t. You can however setup a weak aura to tell you your health is low as a reminder.
