Did he have any special protection in the TV series? I don't properly recall much about it.

Not sure. He didn't get into too much detail with his abilities and protections when he guest-starred in season 4 of Arrow (from what I could tell, same guy). All I took away from his own series was "gypsy magic is the blackest of all magic", which is a total load of phooey. They cast him convincingly, but the scripts were clearly written by someone who didn't know the character. (Contrast with movie!Constantine, which had good (though not great) writing and lore consistent with the character, DC metaphysics, and DC history, but was clearly miscast as a vehicle for three actors' careers over all other considerations.)

He did transfer some tattoo-like protective runes from himself to Ollie in an island flashback scene, though. Seemed to trigger when Ollie got too close to a mystic power source relic, IIRC. I'd imagine TV!Constantine could get his hands on similar protection tats.
