The Nautican Warhammer Battle army has been updated to draft 5.0Important: I have only updated the pdf to draft 5.0 . The Nautican Army list blogsite still contains draft 4.0. I will update this when I can.
The changes are mainly balancing. There are no major new units or rules just tweaks. Several rules have been simplified and some special rules removed.
