Summon Varrangoin

This spell allows a priest to summon one abyss bat (varrangoin) as a servant. The priest can specify which type (I—VI) of varrangoin he wishes to summon. The casting time is 1 round per "type level" (a Type Il varrangoin can be summoned in 2 rounds, a Type V takes 5 rounds, etc.). However, because of the chaotic nature of the Abyssal planes, there is always some chance that the summoning will bring forth a randomly selected varrangoin type. This chance is 50%, less 2% per level of experience of the priest. If a randomly selected type appears, use the table to determine the type appearing:

d100	Varrangoin Appearing
01-30	Type I
31-50	Type II
51-66	Type III
67-80	Type IV
81-88	Type V
89-92	Type VI
93-00	Spell failure: no varrangoin appear

Lesser varrangoin summoned will do the priest's bidding to the best of their abilities, save that they will not behave in any obviously self-destructive manner. Greater varrangoin, however, have to be negotiated with and offered some reward or sacrifice for their services before they will serve the priest.
This specialized and limited form of gating draws forth an abyssal bat for a limited time only. At each dawn following its summons, the varrangoin is permitted a saving throw vs. spell and, if this is failed, it returns to its home plane. Saving throws must be made in the same manner each dawn following the summons in order for the varrangoin to remain on the Prime Material. Varrangoin do not have true names or individual identities, so it is not necessary for the casting priest to be familiar with the details of the creature being summoned.
The material component is consumed during the summons.
