Hiho, here a maybe helpfull glitch on Temple of the Elders Health-Shrines. If you activate the teleport during a recharge of a shrine (the 1-2 sec. where you cant use them). You can still use it after the teleport Activation and more than 2 times. You can also do it without the marble, if you are fast enough. In Coop this works too, if you got the timing right, 1 can activate the shrine and the other player the teleport.

Yeah that was a thing even before 1.2.2 but as with any big "damage" this is a very risky move. One bad spawn and you're dead.
