D&D General Wilderlands of High Fantasy Amazon Warrior typo - Anybody know?

[earthsea_wizard]

Perhaps @robertsconley or someone else who worked on the book:

In player's guide to the wilderlands, the class description says they gain:

Battle Dancer (Ex): Beginning at 2nd level, an amazon warrior may add Ω of her amazon warrior level as a competence bonus to her AC

I am guessing Ω = 1/2? Unsure though...
