I think this would be beneficial to have in your base/arena during events that would be annoying to repawn that many times. The candles would work because it's limited to one specific space so that it wouldn't be too overpowered.I don't see how a potion or candle would do this well... you'd need to have those active when you died. And if you need to prepare something to use just before you die, you could probably use that time to make sure you don't die.
