I WILL concede that I haven't started doing technical dungeons or advanced special dungeons yet. I imagine I'll get into that after I clear the normal dungeons. i'm primarily thinking about clearing the normal dungeons.
This a joke post or troll post. No special or tech dungeons?? You have to beat the special daily to level up any monster all the way to 5*. You won't be getting gate keepers or huge sprites any other way. Tech dungeons give you pengdras. Once open never feed anything else to monster. Have to got colored dragons and dragon plant to evo those things to get max exp bonus. However, a maxed pengdras or penguin dragon still better than anything else. Feed slimes, golems, ogres carbuncles to them to get to max. Only getting 2-3 per tech floor. Also try and level 5 at a time. You need 4 million xp for some of theses monsters. Won't be getting that with carbuncles. If you not playing special you not playing. If you don't have Odin forget about getting too far with weaker team. Find several odins and get a healer as your leader.
