It was one of the main things which hooked me onto this game: sharing that last pip of health with a fallen buddy and saving the run or when everyone is down someone would use their energy and sprint around in an attempt to bring everyone up, often when very deep into the clockworks everyone would still die again and someone else would take the turn over and over until no energy is left and even though the run itself failed it still would've left a good aftertaste. Those were one of the best memories from almost every play session and reason for me to return to SK every day.
At the time it was a very unique mechanic, maybe SK even pioneered it. This days it is shared by most co-op games and loved by the communities of those. To this day I hope that one day I will open the announcement page and see that revive poke is back and yet again brings the joy and reason for knights to create and join open parties, to save others and be saved by strangers, as well as make new friends to explore the clockworks with. Sorry, I got a bit nostalgic here /giggles
You're talking about reviving a fallen comrade by sharing half of your health with them? I agree, that it was a nice teamwork dynamic.
It was removed in the July 2013 mega-update. It was sort of replaced by sharing Sparks of Life, but that is psychologically different, because Sparks of Life can be hoarded and therefore must be hoarded. ;)
