Topic Summoning Stone
The ones next to the older dungeons are still good for summoning guildies who want to complete dungeon achievements... Or for summoning people to do FTA/FTH. They're still good for something. =)
I made a quick video on how to use these stone, I made it after a guildie asked how to use them, he said he couldn't find much help on how they work online.
hope thid helps : )
