Jungle Temple Key in a New World

[RayDaug]

I just got back into Terreria after over a year because some freinds of mine started playing it and I want to stay ahead of them in gear. Only issue is that my main world is super old and doesn't have a Jungle Temple, so I can only play up to Plantera, which I have. Can I take that Temple Key to a new world and pick up where I left off, or do I have to do the whole process?

Have to do the whole process.

You don't need to start a new char, but you can take the jungle key to a freshly generated world and progress that world. But you need to play through the game's progression. That means killing the wall of flesh to start hardmode, followed by killing the mech bosses to activate the jungle's restlessness. At that point you can open the jungle tample and proceed from there.

The rest of the game is pretty much optional, but you might find some advantages from killing the other bosses. Maybe. Okay, probably not for the point of progression you're at. But on the bright side, at least digging the hole to hell will go faster with your hardmode mining tool.

@Drag, you can actually open the temple without having killed plantera, but you cannot summon golem. Otherwise as you said OP just needs to rush WoF and Mech Bosses then kill Plantera.

Thanks for the replies. A bit of a pain, but I've already killed two of the three mech bosses. Most tedious thing is switching between worlds since I don't feel like establishing a new base.

oh and a word of advice (probably you already know, but anyways) remember that after killing all the mech bosses you have to wait 1/2 terrarian day for *1* plantera hub to spawn, so you might want to let the game open for 30min to start farming for those hubs
