The full Stasti alphabet, along with a bit of the numerical system. Formal Stasti has very strict written rules–each word is composed of alternating vowels and consonants, with no double consonants or double vowels allowed (hence why there are so many single letters for "compound" sounds). A lot of these letters are pretty infrequent in the actual language; the "y" consonant, for example, is only used in more archaic words.
Also: pronunciation is just as strict as spelling, so here's the correct pronunciations of each of the vowels:
A as in "lawn"
E as in "exit"
I as in "inside" (pronounced "teeth" at the end of a word)
O as in "open"
U as in "under"
EI as in "teeth"
AO as in "house"
AI as in "nice"
IA as in "yawn"
