Yan-C-Bin is naturally invisible, creating a slight disturbance in the air
as he flies which may be detected by high-level characters (see AD&D DMG -- Invisibility).
He is about 10' in diam. but has no definite shape.
He attacks as a 19 HD monster twice per round for 2-20 HP of damage each attack,
with the same chance as that of an 8th level monk to stun or kill an opponent outright. <>
+2 or better weapons are required to harm him. <>
For purposes of aerial combat, he is manoeuvrability class A.

As Prince of evil aerial creatures, Yan-C-Bin can summon one of the following groups once per day:
1-3 air elementals, 1-4 cloud giants, 1-4 invisible stalkers or 1-3 wind walkers.

Lightning attacks are ineffective against Yan-C-Bin, but fire attacks
against him are at a hit probability bonus of +1 for every four levels
of the attacker (so a 3rd level character would get a bonus of +1, a
seventh level character +2 and so on). Yan-C-Bin cannot be harmed by
any object CAST into the air and is immune to petrification. He can
form a whirlwind -- a truncated reverse cone, with a 2" bottom
diam., a 6" top diam. and a height of 16". If the full height of the
whirlwind cannot be attained due to some overhead obstruction
the whirlwind is only half strength. A full strength whirlwind sweeps
away and kills all creatures under three HD and causes 4-32 points
of damage on all non-aerial creatures which it fails to kill outright.
(A half-strength whirlwind does 2-16 HP of damage).
Yan-C-Bin can sustain this form for 2-5 rounds.
Formation of this whirlwind or dissipation of it requires one full round.

Yan-C-Bin lives in a great airy palace on the Elemental Plane of Air.
