Is there any self damage that can proc Orian's Sun Seal?

I’m messing around with Divine Flare Symbols of Hope. The idea was going to be to automate casting it with smites eating my health to drop me bellow endurance threshold. Unfortunately, you need to actually be damaged, not just have health consumed. So it didn’t work. I’m aware of 3 items so far that can deal self damage, but I don’t have the two that are easier to test with (Calamity only happens on kill, so I can’t test on dummies.)

Before I spend what might be a sad amount of time farming for Immolator’s Oblation or Grasp of the Blood Mage, does anyone know if this is an interaction that works at all? Also if this works, are there any other methods I’m missing? I wouldn’t think the health lost per second items would work, but they’re worded differently than “consume”, so maybe?

EDIT: I got lucky and it didn’t take too long to find an immolator. I can confirm it does work, but I’m gonna need a lot more endurance threshold to make this consistent.

It’s not too difficult to get via the Weaver node that adds mobs from dungeons.

There’s also the amulet that gives a stack of bleed on spell cast, but the damage from that is minor.
