Ok so brick went to the new world today as a lvl 43 PLD/RDM to get dancer. here are some of my findings.
Rolanberry Fields [s] is where the cavernaus maw from batalia downs (see pic above) dropped me.
In Rolanberry Fields [s] at H-6 is drops you. heading up towards the bridge to Batalia I came accross 3 types of mobs.
Death Jacket - No agro registered Ep-DC to my 43 pld.
Death wasp - EP no agro (see pic below)
Lycopodium (a type of mandy) too weak - EP
Heading to Batalia through a gate (no access to jeuno)
This map i have edited. the red line shows the rampart that you have to go through to get to Jugner for Dancer quest. The area to the east of the rampart where you enter the mobs are registering too weak to DC to my 43 pld, it is quite safe there for a lvl 40+ character.
Mobs there are as follows
Ba - Bird - too weak - DC (no agro)
Lycopodium (mandy) too weak - EP (no agro)
Stalking Sapling too weak - EP (no agro)
Sadly too weak - DC (no agro)
To the west of the rampart are higher level mobs. I only saw the following.
Goblins 3 types, all IT++ to me Best cast invis.
Smilodon (see pic) Tiger need deoderise and invis and sneak (according to wiki) is a lvl 55 according to wiki, obviously registered as a IT++
Wight (skele) Nightime, need sneak was DC-IT+
I did;t see other mobs during the route to Jugner.
In Jugner I saw 7 mobs.
Wondering Sapling too weak - EP (no agro)
Lycopodium (mandy) too weak - EP (no agro)
Biddybug IT++ (see pic of bug with 2 75's fighting it) is apparently lvl 64+ according to wiki.
Stag Beetle IT+
Land Pugil Ep-EM
Sniper (crab) Ep-EM
Hawktrapper (flytrap) DC+
Snipers, hawktrapper and land pugil (ep one) did not agro me when sneak, deoderise and invis expired when i was at lake to get stone for dancer quest.
hope that helps, remember thats my sightings and experience as a lvl 43 PLD/RDM galka.
