Spawned this guy twice tonight without really trying, so I'm thinking that it's a pretty common spawn. The spawn location both times was around -680, 665, an octo-mech patrol is the ph. Dropped ring both times.
The multiple drops listed above go together like this:
Mechanoinstruction Scraps (. d . i . o r . . b . . k) Mechanoinstruction Scraps (a . v . s . . . . . . o .) Mechanoinstruction Scraps (. . . . . . . y . . o . .)
Mechanoinstruction Scraps (c o . . . g . . . . . . n) Mechanoinstruction Scraps (. . n . . . . . a . . . .) Mechanoinstruction Scraps (. . . f i . . . . . i o .) Mechanoinstruction Scraps (. . . . . . u r . t . . .)
Mechanoinstruction Scraps (M . . h . n o t a . i . t) Mechanoinstruction Scraps (. e . . . . . . . . . e .) Mechanoinstruction Scraps (. . c . a . . . . b . . .)
I believe that they have changed the Speckled Mushroom Band to be the Common Drop. As the octo-bot dropped it everytime, but no Forlorn Blade dropped.
I joined a group that was camping the Octo-bot. The PH, an Octo-mech Patrol, spawned about every 15-20 minutes. Had the octo-bot spawn in the cycle once outta 4 PH's one day, and then not at all out of 4 PH's the next day.
Very easy camp for 3 of us, Warrior, Shammy and Druid all about lvl 60ish. This is considered an Outside zone as all druid buffs worked.
