Siege Devourers can be ridden 'twixt zones.

Just thought I'd pass this little bit along; I picked one up in the Highlands and rode it around the Valley doing Fire and Pain and just generally laying waste to things with siege attacks.

You can also go back to the original zone and there'll be a new one there. I have high hopes for setting up a guild force some time and roam around causing utter havoc. Think three or four would do the job, with healers and maybe a MM for backup? 
They don't go underground however, unfortunately.
How'd you deal with the Burning Spirits, by the way? I tried going in with the siege devourer and my heroes on interrupt duty and still got wiped by Mr. Burny and his four pals. I'm thinking that maybe I should have had the heroes set more for anti-spamming like Diversion rather than straight interrupts, but since you've done it I figured I'd pick your brains to see if you have any suggestions that could let me do it without having to wait for the guild to catch up

THAT set caused me no end of sadness; the regular groups of 3 go down pretty fast with a siege attack + henches to mop up (Pyre's on Barrage duty, Vekk used some AOE water attacks, etc). The boss group wound up being attrition; manage to take down one, die, manage to take down 2 the second time, die, finished off him and the last 1-2 on the third run. -.-I'm sure there's a slicker way of dealing with it, but I probably don't have the skills unlocked for it.
