Updated.
Shall we work on Mullonga's underbar?
For the heads? Sure.
I suggest giving them at least the maximum HD of a standard arcane head and preferably more - I'm thinking we should increase it to 6 HD.
Then I'd give them the elite stat array.
Head Racial Bonuses: Str -6, Dex +10, Con —, Int +0, Wis +2, Cha +2
Elite Array: 15 14 13 12 10 8
Str 14-6, Dex 15+10, Con —, Int 10+0, Wis 13+2, Cha 12+2
Mullonga's Arcane Heads: Str 8, Dex 25, Con —, Int 10, Wis 15, Cha 14, Hit Dice 6d12 (39 hp).
They'll also need an improved (
greater teleport plus
plane shift) version of Summon Mistress:
Summon or Dispatch Mullonga (Sp): A group of Mullonga's arcane heads can summon their mistress Mullonga, but only if the hag wishes to be summoned. Five or more arcane heads fly in a circle for three rounds, tracing mystical patterns in the air. Mullonga then appears in the center of the circle as if transported by a greater teleport and/or plane shift spell. Alternately, if the hag mistress is already present, this ritual transports her to her previous location or another destination of her choosing (subject to the same restrictions as greater teleport and plane shift).
If an arcane head of Mullonga is damaged or prevented from moving, it is unable to contribute to the summoning, but provided at least five arcane heads complete the ritual without interruption, Mullonga will appear. This is the equivalent of a 7th level spell (CL 15th).
