Even though I AFK farm, if you're looking to burn through stamina in a hurry (like before leaving for work), time is a factor. 12-3 is great for this (I have a dedicated speed team for farming 12-3 with 1137 Speed for this). I put that massive speed team on the upper left camp, so they skip the left and bottom sides and go straight to the right side (where the flag is), while the rest pile on the middle node to pick up all chests (4 chances at 50/50 is still pretty good). The 4 others get 1-2 fights in, while the speed team burns through to the flag in like 3 minutes on auto-run (literally about a minute if I'm click-spamming). This is also good for if all you're interested in is SGs and a low chancy of ampy.
Reviving this thread for my question, trying to get Lv.100 dragons for evolution, is there a good map level for this? BTW I'm on DMM, but I assume it's the same (more or less...?). Don't really care if stamina draining or whatever just hit me with some ideas, I'm been frustrated all day trying to get some, only got 1 so far
Just do the 80 stamina one, and pray to RNGesus.
You started only recently, didn't you? Then other than that, there's not much more you can do. Maybe hope that next event will be a card flip one.
