Is a pack yak better or lava titan? Is there a mining level at which the pak yak becomes better than the lava titan?

good question, I was wondering the same thing, in W84 I rarely get hit anyway, so isnt the pak or war tourtoise better? less running back and forth.

The reason people use the titan is to gain that invisible mining boost, which makes you mine a little faster, and increases your experience gain per hour. I personally would use the Yak/tortoise because of the amount of ore I can get per load.

Superheat the gold as you mine. Drop the gold bars. Use lava titan.

I'd use a titan, just because for the most part, finding your own familiar might take a little extra time which would defeat the purpose of having it there.
