You probably know by now that the game is DISGUSTINGLY P2W in PVP and yet this mode is structured so that P2W players will just go past you without problems and this makes it quite balaned and ALSO a good way to earn Gold+Gem if played correctly

Rules state that they only allow you to go to the next Tier according to your level. They are Even levels 4,6,8, 10 etc.

Ok now comes that strategy. I will not discuss what heroes you will use sicne I cannot plan what startegy you like or like to use


1. DO NOT LEVEL UP TO ODD NUMBERS
If you are already nearing level 6 or 8 for example just STOP.

The idea is to make use of the Tiers to allow you to quickly finish your mine and just restart over

Your job now is to make sure to calculate your CLAN DONATIONS AND MONSTER UPGRADES.

2. START COLLECTING MONSTERS YOU PLAN TO USE IN ALL MODES
I am pretty sure everyone has their own style of play so the strategy is to SAVE as much and as quickly the monsters you like to use. Its a good idea to have them at least 2 levels above your current one.

3. ATTACKING can be planned DEFENDING on the other hand will be countered

Attacking gives you the options you need to succeed while DEFENDING is harder IF you did not plan properly. DEFENDING successrate is usually based on monster levels and luck.

4. RANKING UP WISELY

Now the actual game mode.

AT the start yoiu are suually rank 95+. Your Goal is to ONLY fight ranks that are 15+ levels ahead of you everytime.

So 99 target 79-85, 79 target 59 -65 etc. The thing to note here is you will have to watch how much Gold you can steal.

If Rank 79 only gives you 1000 Gold while rank 81 gives you 20000 ALWAYS pick the larger number

Once you reach rankes 20+ with 5-6 rumbles is the part where you will count and target the LARGEST Gold steals you can.

If you managed to get good results your total time normally should be around 4-6 hours completion while BEST steals will get you completion as soon as you end all 5 rumbles

MEANING

DUE TO YOUR LEVEL it ends and gives you your prize AND you can now Mine defense again not haviong to rank down OR wait 24 hours to finish

5. IF DEFENDING FOR A FEW HOURS
Hopefully you are in ranks 1-5. If you see that the Gold steals are not good I would suggest you try to at least reach those ranks AND KEEP 1 rumble for DEFENSE. Check back in an hour or 2 and if ranked down Go check how much Gold was stolen and ALWAYS target Gold STeals that give you more in return
