Advanced Orc Barbarian Monster Kit
Make yourself look a bit specil
While Profound Decisions provide some basic kit for monstering (a mask, medium armour, and occasionally a scarf in an appropriate colour), if you can bring a couple of bits of your own to monster in, you'll have an easier and slightly more comfortable time.
Some of your character's base layers might also be usable for various barbarian nations, but I'd always recommend having a spare set of basic base layers in a neutral colour so you don't have to wear the same sweaty clothes you battled in for the rest of the day.
COLOURS OF THE BARBARIAN ORCS
Think "Evil Navarr"
The Druj favour poisons and stealth - and wear a lot of green and yellow, including acid greens (usually brighter shades than typical Navarr). They are neighbours/ rivals of Dawn, Navarr and Urizen. They use fear as a weapon and are often adorned with poisonous insect imagery, and bone accessories.
Think "Purple Freeborn"
The Grendel are a seafaring commerce nation and neighbours/ rivals of the Brass Coast. They wear mainly purple with orange highlights, and show their wealth in accessories. They are professional soldiers that are vaguely Roman themed.
Think "Red Wintermark"
The Jotun are a militaristic nation and neighbours/ rivals of Wintermark. They favour "honourable combat", and dress similarly to Wintermark - furs and leather and chain over blood reds and browns. Some specific tribes (the Lasambrians) use Orange as a contrast colour.
Think "Blue Varushka"
The Thule are a magical nation and neighbours/ rivals of Varushka. They wear a lot of dark blue - it's their favoured colour, with hooded robes and dragon/wyvern imagery. They may also have intricate Wintermark-style runes painted or engraved on their costume.
NOT NECESSARY... BUT AWESOME
