Outward: Definitive Edition

So, it's very easy to do this. There are some items that, if consumed, increase resistance to cold (which is important as you can get a cold debuff if you are exposed too much). As a complementary defense, you can use equipment with some resistance to cold. The items to be consumed are:

Bitter Spicy Tea (Water + Ocher Spice Beetle)
Boiled Dreamer Root (Dreamer Root, I mean, self-explanatory)
Cipate (Meat + Salt + Egg + Boozu Flour, this will give you another achievement)
Gaberry Jam (4x Gaberries, this one too)
Gaberry Tartine (Bread + Gaberrie Jam)
Ocher Spice Beetle (Yes, eat the bug if you are in trouble)
Pouding Chomeur (flour, egg, sugar, Boozu milk and this)
Poutine (can only be purchased)

Once the defense is up to 25, the cheevo will pop
Happy hunting!
