Is going to the laggy world where everyone else is worth it? I'm 138 cmb with ee

Lava titan or yak? I'll be banking cuz I cbf dropping don't try to convince me otherwise

I always use world 77, far less laggy than 84, yet there are still enough people that you won't need armor or any form of healing.

 

Personally I use a Yak, and it seems to be faster xp than a Lava Titan, although it's a very fine line. Remember that using a Yak with a whole bunch of other people will get very annoying. It might be best to use a Titan just for convenience.

If you are talking about world 84 or whatever the lrc world is, you should try world 2 or 77 or any other decently populated lrc world. You really don't need a lava titan so a yak would be best exp wise.

Yak, EE, coal bag (if mining coal), and decent armor and you should be fine.

Lava titan, and just go to a normal world. You can just lure the mobs.

W77, use lava titan and you shouldn't need any healing at all.
