coffer mobs are on the third map. Take the entrance to the Den of Rancor, follow the right wall and you will zone into the third map. Same area as the offering for the Carbuncle Mitts.
Nothing new posted in a long time so i will post something :D Yes the mob are on the third map,for someone who doesnt know the directions,if you enter from the main building structure outside from YHotoar Jungle you head towards K3 of first map.Even if you dont have a map,you can still head to K3 easily,and not ***** up.
For those that wonder about the drops and rate, i had no thief or sub thief.I got 2x RDM testimony real fast like 2/4 kills,but i did not see another for the next 2 hours.Got a couple spell scrolls,2x coffer key.I would say to expect 1 coffer key an hour,but it could possibly be and is probably MUCH quicker for a thief to steal one.
As far as the HOVER tank key drops go,i did not find them to drop other than spell scroll.I got both testimonies and the keys from temple bees.A 75 with healing help,probably even with just /dncr can handle 2x bees,so if you have a problem getting to them because of tonberry and finally do,might as well grab 2 while you have the chance.
Sam or /sam is nice because you probably want to zone all the tonberry you aggro or force aggro,so having Meditate to give some auto TP for dncr or /dncr is handy.However as a 75 there really is nothing to fear ,you wont take damage fast enough that you cant fight as /dncr with zero tp,just drain and heal as you get the TP.
I think the stories about the COFFERS are true,they seem to spawn more often in behind the doors that need a prelate or uggalepih key,so you will need to kill the tonberry,because like i said,the Hover Tanks do not drop them much at all,no one i asked when there got any key from the Hover an we killed amongst us maybe 50+.
Yes you better have some form of invisible if you are not a 75,everything map 1/2 is safe to a 75.
I forgot to mention for any new playerr that once you head to K3 of first map,you will go outside then do a sort of U shaped turn and head back into the Temple,as soon as you zone in you will head down a sort of short spiral stairs and the you will see the mobs right there,as i stated just zone the Tonberry out if you dont want to fight them.
