How do you get a hero to keep blessings on you?

I was playing around with my heroes and am trying to figure out why they can't keep blessings like Mending or Watchful Spirit on my character. I click my character and then click Mending on the hero's bar. That should put it on me right? When it is cast the Mending icon briefly appears on my screen but then disappears.

Can heroes not maintain blessings?

If I recall correctly you need to disable the skill on their bar (shift click). Then target yourself, and manually click the skill.

yeah u have to disable the heroes skill by using the shift clicking on there skillbar. It will have a red circle with a slash through if it disabled.

those are called enchantments. Blessings are entirely different things
