For this achievement, enter the Gyel Fortress dungeon, normal mode. You will need 2 or more people to kill the bosses, and you will have to have a pet spec to get to Infernos that are stuck in the landscape. Don't kill bosses until you've cleared all the Verderbendes Inferno before the boss, or they will despawn. Here's a list of coordinates of the Infernos in the order of finding them: 1. 1x (956, 1503) 2. 1x (969, 1523) 3. 1x (886, 1507) 4. 3x (897, 1462) 5. 4x (784, 1406) (To get to these, follow the wall, and climb up the diagonal ledge sticking out of the floor, jump onto the wall, and follow the top of the wall. Jump over the barrier near the end, and you can kill the 1 up there, enter the hole in the wall, and kill the 3 in there. Click the Orb of Transformation in there to get out) 6. 2x (772, 1362) 7. 2x (883, 1310) 8. 2x (1012, 1346) 9. 1x (1211, 1121) 10. 1x (1172, 1150) 11. 1x (1146, 1136) 12. 1x (1239, 1142) 13. 1x (1067, 1152) 14. 1x (1067, 1132) 15. 1x (1005, 1119) 16. 1x (1005, 1163) 17. 3x (838, 1139) 18. 1x (773, 1149) 19. 1x (770, 1179) 20. 1x (770, 1099)
