If you’ve ever played World of Warcraft you’ll know the Hearthstone and the benefits it can have. If you haven’t then it’s a totem you carry with you at all times and will transport you to your home base when you use it. In Minecraft it works much the same way.
And then at any time you need to return home just use the hearthstone and you’ll be instantly transported.
But bear in mind that there is a 30 minute cool down after each use so only activate it when you need it most. It makes for great control in being able to return home in an emergency instead of constantly having a teleport functionality. This would be perfect for hardcore servers that just need that extra bit of protection now and then.
