If you attempt to use the Abyss Lord's Abyss Stones or Abyss Fountain when you have insufficient Ability Mana, the message incorrectly shows a green crystal (representing Build Mana) instead of a blue one (representing Ability Mana).  These abilities use Ability Mana, and should show message that states "NOT ENOUGH "

Reproduction Steps:

1. Attempt to use Abyss Stones or Abyss Fountain when you have insufficient Ability Mana remaining.
2. You will receive a message stating "NOT ENOUGH" and a green crystal, when it should be blue.

Screenshot: (Note that I have sufficient build mana for all my defenses.  I am attempting to use Abyss Stone here.)
