Bubble Trouble: A Geomancer Guide

The correct answer is to entrust strength on your dds. If your mages are running out of MP when you get a full MP refresh every time you go up to a new floor I don't know what to tell you. Most groups only bring geo and red mage, and neither of us should be running out of mana in there.

Floor warp MP refresh is a good point, but while refresh bubble isn't the best example for limbus climb I'm sure there are the occasional beginner groups that pick to high of a floor lvl than what they can manage and if he has to ask he might fit that description.

If you brought SAM and the mobs aren't much of a challange then STR bubble is a good choice.
If you brought a Rudra spamming THF then DEX bubble might be the better choice.

What I was trying to point out is it's better to be aware of the situation you're in than following a blank statement that possibly doesn't fit the individual circumstances.

The only time I run out of MP on GEO is when I spam Curaga3's carelessly as GEO with Raetic Rod +1, and idle in Raetic Bangles +1. I steal hate from idle mobs when they wake up, they smack me a half dozen times, and the bangles drains my MP (kind of funny, but a non-issue). If GEO runs out of MP, Radial your bubble or Aspir it back (most mobs in Limbus have MP).
