I have done this a couple of times and each time only 1 Water Elemental for the whole leve duration would pop thus rendering the whole leve a big whopping fail.

Twin Adder Grand Company Leve at Treespeak "Sylph-inflicted Wounds" on Lindblum server.
  • Nibbled Toadstool x2
  • Water Elemental x2
  • Lightning Elemental x2


Don't know if it is just me but thought I should give you a heads up.

EDIT: I killed about 10 Lightning, 6 Toadstools, and the only Water was at the very start.
