I noticed that once I got near to the last boss stage, the only raid that spawns is the wolf hunt.
I'm guessing that once Mistlands is complete, there will be a Plains version and I guess, eventually a Mistlands version. I always carry a levelled atgeir, so I don't find wolves too much of a problem, but I tend to move around the map a lot, so I rarely get raids near my main base. I usually just use either the landscape or other creatures to distract/defeat the main brunt of the wolf attack, then pick them off.

I've had 3 Troll raids within 1 day of each other.

I got hunted about 30 seconds after entering the snow biome. I had just killed bonemass the day before, so I wasn't ready for a whole pack. The timing was even worse because it triggered just as I engaged my first wolf.

Wolves say "nom nom."

I'm jealous, that's a lot of Wolf meat!

Yupp, seems to the most random event of the game i did experience. Sometimes takes ages to happen, then you can get 2 in a row and it seems to happen a lot when its totally inconvient. But thats probably an illusion.

Lucky! I wish I could get consecutive raids from drakes and wolves more often. I've only gotten a Surtling raid, then a troll raid right after.

It’s entirely random. 20% chance every 45 minutes i think.
Except the only thing that can happen while you’re out in the field is wolf meat.
