Forgotten Ruin Map?
When can i go to Forgotten Ruin?
When do i get the cordinates for it?
What lvl are the mobs there?
Level 95, you will need a ring from the Desert Scream grocer to enter it. (Similar entry like undead ground.) The entrance point is near the Lug Queens.
If I recall right, you get a quest for the map/warp code at level 95 as well, not sure anymore though.
The mobs are I assume between level 95 and 110 (the level which opens up Lakeside), but the bosses who walk around in Forgotten Ruins are a bit stronger and probably at a higher level.
Keep in mind though, this is the first map you will experience with war settings enabled. So it will be a bit like CH7
