I have been camping this named for about 10 days now (well ... ten, 8 hour camps). He does not spawn very often. My best was to spawn him 3 times in 8 hours. My worst was no spawns in 3 days.
His place holder only spawns every 30 mins. and is "a lost rotwood". He is a stationary mob at roughly -970 by 2734 (South West corner of Goru'ka on the plateau there).
I have gotten roughly 14 named to appear in those 10 days. I have only gotten the aug once so far. (was really hoping to get a couple for my friends :-(
I obviously am not paying too close attention, but the there are roughly 4 other roaming trees. None of them are the place holders. 4 roaming mobs and the place holder all at once is too much for a lvl 69 mage with a merc out to survive "unattended". :-)
Otherwise the mage has NO problem handling 4 or 5 mobs (with out the named) if you are paying attention.
Hope this information helps some one out :-) Thank god I am doing something else. This is a VERY boring camp :-(
Has ~45khp, Flurries, Lifetaps, casts Wind of Corruption, and has a damage aura like the other treant mobs in the blighted area of the zone, and does not run.
I didn't get close enough to get hit with his damage aura, but my experiences with the other treants indicate that it is a 200 damage per tick persistent effect that cannot be resisted or disspelled (although spell shielding does reduce the damage), it breaks Feign Death if the mob wanders over you while you're feigned, and you can clearly see the area of effect if you have your spell particles turned on. Looks like little puffs of black smoke.
Respawn rate for the trees is closer to 5 minutes than to the 20 minutes posted somewhere else, but Ternsmochin seems pretty rare.
And after four friggin' days of camping this pile of sawdust, all he drops is the damned shoulder piece. >.<
EDIT: Attempt two
I noticed in my combat spam "Ternsmochin goes on a WILD RAMPAGE!"
Dropped the shoulders again, but I noticed and confirmed a few more things. He was up when I logged in at roughly the same time I killed him, so he may be a daily spawn, but still no confirmation on it.
His damage aura is 200/tick, just like the other trees. He may also cast the spells Asystole and Drain Spirit, but I got an add when I pulled him, so I'm not 100% sure on that. I resisted both.
This time, in addition to the shoulder piece, he dropped Treant Bark, Treant Heart, Straight Treant Branch, and Bloodstone.
Try #3:
I can confirm that it is NOT a 24 hour spawn as I had thought earlier, as I killed him again within 4 hours, and he FINALLY dropped the augment.
