The Eidolon's rank determines its stats when summoned to battle. The rank is the sum of the character's Crystarium level and the number of level 5 roles. Thus the maximum rank is 16 (Crystarium level 10 + all roles at level 5).
A cracked tongue may indicate an oral yeast infection, or oral thrush. Oral thrush is caused by the accumulation of the candida fungus in the lining of your mouth. In addition to cracks, symptoms of oral thrush include pain, loss of taste and lesions on the tongue and other areas in the mouth. A weak immune system, diabetes, cancer and vaginal yeast infections are all causes of oral thrush, according to MayoClinic.com.
Other Causes. Constantly eating spicy food, exposure to stress or grinding your teeth can lead to cracking of the tongue. Oral thrush, a yeast infection in the mouth that often accompanies a weakened immune system, can also increase your risk of cracking tongue. In some cases, conditions may cause bumps on the tongue or swelling that can be mistaken for a cracking tongue.
