I payed a fortune for it.. but upgraded my tellurian recruit apprentice III to adept III. Life seems so much safer now. I'm 17th level. If you can find yourself the rare resource to get your adept III, set your teeth in it Good spot to waste all the money you made Dunno how strong adept I's are though Cheers. Just sharing my happy thoughts.
I have Adept III's in Tellurian Recruit, Aggitation, and Invisibility. (10th - 19th) The Adept III pet seems to be extremely strong. I've had it since 10th though, so I never compared it to the beetle. Adept III aggitation seems to yield one butch pet that holds aggro very well. I can't tell any difference between App3 and Adept III invisibility.
Yeah the Adept3 pet is pretty good, too bad it becomes obsolete at lvl 24 though. I would much rather have the Adept3 pet buff.
