Hound mound respawn times

[Kit-tay Pow-ah!]

I'm playing adventure mode and I started out on the archipelago map. Right next to the spawn is a patch of about 8-10 hound mounds. I prudently ran away and set up a base elsewhere, but now I have returned to the mounds to try and destroy them. I don't think the mounds are guarding anything important but I want to kill them anyway. My problem is that fighting the hounds is like swimming upstream. After killing 20 hounds I had to back off. Every time I kill one hound, the mound seems to instantly spawn another. Does anyone know how the hound mound spawning works? Is it like spider dens, where once you kill all six spiders they only respawn one at a time slowly?
Are the mounds flammable? If they are I could do hit and runs with the fire wand. I could try to blow dart them, but I'd need about 30 darts to get them all.

Thats an intresting question. They haven't said anything on the wiki so I guess we really don't know that much about hound mounds.

From what I've seen, they only respawn one at a time, but the spawn period is fast. Like 10 seconds or so. I think the max they spawn is 4, but again, that's just my eperience, I haven't dug into the files (Hey! Maybe I should so I can update the Wiki!).

Since they're basically bone and rock, I don't believe they're flammable, but I haven't tried. Give the fire staff a whirl! Blow darts wouldn't be bad, if you can even take out 1-2 mounds, that will ease the burden.

Quickly tested it just now.

Hound Mounds have a maximum occupancy of three hounds per mound.
Each Hound Mound has it's own spawn timer.
Hound Mounds are not flammable.
One Hound spawns every 30~ seconds, although after the first hound dies another will instantly take it's place. I figure the respawn timer must be sitting there with a hound already locked and loaded but it can't fire due to the three hound limit. After that 4th hound pops out, it properly starts the 30 seconds until respawn rule.

That's good to know, thanks. I don't think I could take on 10 hound mounds in a straight fight. By the time I kill each wave it seems like the next would be ready to go. Probably need to lead a deerclops there or plant a bunch of spider dens on one side of the mounds then sneak in the back and destroy some of the dens.
