lunar has 3 pathways.. 1st) .. kill only the tomb stone on the left side when you get to it.. (don't kill the one on the right.. )2st) .. do the same .. but only kill the right tomb this time.. and the 3rd path.. requires you to kill both tombs.. each path has one card boss summoner i believe.. :S by tombs i'm referring to the the physical immune ones you have to kill before killing the first tower boss... idk if this made any sense to you couldn't write it in much more details. can't think of the exact terminologies off the top of my head at this moment :S .. pm me ingame.. . i can run you through the lunar runs .. real quick.. if u need help.
1st card boss is always after Genesis Blink, no matter what you kill. Summonbot is right before the teleporter, boss spawns in the water.2nd card boss is in the 2nd Valley after you kill the left tombstone only, then Genesis Blink. Teleport to the next Valley, kill the first group of mobs and the Summonbot will appear behind you.3rd card boss is in the 2nd Valley after you kill the right tombstone only, then Genesis Blink. Teleport to the next Valley, kill the first group of mobs and the Summonbot should appear right in front of you, boss is in the water.
