Kind of a dumb question, but ever since finding out Holy Symbol now gives the full EXP boost regardless of how many people are affected by it (HELLO +50% free EXP all the time), I'm wondering, under the conditions of having a laptop with me as I Maple, is a Phantom buff mule worth getting? I do suppose if nothing else, I can use the mule to immensely speed up training when it comes to getting to 4th job faster.
From what I read, Mystic Door doesn't work in LHC, so a mule there won't work. I read that Mystic Door at Knight's Stronghold works, so would it technically be possible to bring an 80/130 Phantom buff mule there? I list 130 in case I feel like mustering the energy to get a 130 Phantom mule just for the 4th job buffs like Sharp Eyes/Speed Infusion.
