Okay basically all you need is Second wind talent and a Winter Veil disguise kit, and snowballs.
Since when you activate snowman with the kit it acts as a stun, and it procs second wind. You can repeat this again and again until you have full rage, perfect for guarding nodes.
Also if you are a warrior in a party and you get knocked down by a friend snowball it is also a stun and does proc second wind, you can also get full rage this way too!
