What is your favorite Heart in the game and why!?

I like "honor the sacred bear"
The one in the starting norm area where you feed the baby bears fish... and they get hearts over their heads.. awwwwwww

awww, mine is the last one you do before you hit lvl 80   

Have to agree with Hunny on that one.

Otherwise...one that stands out for me is the pirate cave in Bloodtide Coast, where you throw bottles of rum at the pirates, piss them off and then incite fights with their neighbors. And you can glitch the passed out pirates, continually "activating" them and making them convulse and groan repeatedly.

My favorite heart is a finished one where I don't have to go back hahahaha

LOL, I love all of your answers and can't disagree that the last heart of a map completion is my favorite

However, my favorite heart in game is Strixies ....totally sappy, but true nonetheless   

....still like the last heart I complete on a map, but shhhhhhh, don't tell Strixie

I like the one where I get to play with the puppies and they roll on the ground and I tickle them and rub their snout and belly and then little pink hearts flutter in the air.

All of the nonexistent ones in Orr.   
Although I kinda like the Raven one in the Norn starting area. I love riddles, and wish more of them were like that.
