Downed lifesteal
You might be referring to symbol of Judgment. It’s a symbol we can use in the downed state to heal and damage.
Noooooo, he was shooting some kind of beam at me and healing from it as it hurt me. Then again he did teleport like from insane distances so maybe he was just ‘funny’.
The beam itself doesn’t heal him. Chances are he put down Symbol of Judgement, which very rapidly gives him large chunks of health back in the downed state, then continued firing his 1 beam at you.
As for the teleporting, guardians can be surprisingly mobile with the right skills and weapons equipped. A lot of guardians tend to run with hammers and staves using the AH build, so you might not be used to some of the lesser seen abilities we have access to.
We have Judge’s Intervention which has 1,200 range but requires a target, Flashing Blade with 600 range which also requires a target and a sword equipped and finally Merciful Intervention which teleports you to an ally within 1200 range (rarely seen in my experience).
