It says in the Armor section p.176 that if you don't wear armor, you use your profficiency in unarmored defense.
B. BLUE DRAGON'S BITE, page 12 wrote:
Any PC who fails the DC 15 skill check is caught and kicked off the ship, but as long as two or more PCs are not caught, the rest of the PCs may board the ship without being noticed. If the people on the docks notice two or more PCs, they conduct a thorough search, and find all PCs who did not succeed at the skill check by 10 or more. Thereafter, the DC of skill checks to sneak aboard the ship increases to 25.This utterly baffles me. If two PCs succeed, everyone may board the ship. If two PCs fail, a thorough search is performed finding anyone that didn't exceed the check DC by 10 or more. A hardline read may be too penalizing. How did you handle this at your tables?
this also confuses me. I find the instruction contradictory.
