Level up without stressing yourself

Getting your PvP team together in Adventure mode can be complicated. I.e., using termis in PvE is a hellish experience, because they have too little damage. Going through levels is very slow paced. A termi team is bound to stick to Ruins 5 until he's finally ready to take on Ruins 15. Yep, you can see the gap here. A classic termi team has to be around level 20 just to take on Ruins 15.

So the first piece of advice I have to give you is: just stick to Ruins 5 for a while. Regardless of what team you're using, trying and failing to go through the highest ruins level you've unlocked soon becomes a major pain. But you can move on to Ruins 9 once you can complete it quickly enough.

Ruins 15 is great, because it's much easier than Ruins 13, 14 and 16, yet it still awards a lot of SLP . You can complete all 50 SLP from adventure using as few as 7 energies. That means you can finally start getting rewarded for winning in the arena. It might take a week or so to get there, but it's certainly worth it.

Eventually, your Axies can manage Ruins 20 with very low effort, since enemies in that area kill themselves. If your Axies have high enough health, you can let them get blown up, because they'll still enter Last Stand mode. Suicide attacks on Last Stand Axies don't instantly kill them. It acts like a regular attack, only removing two Last Stand bars.

If your team takes a really long time to reach this point, worry not! It'll eventually get there, because Axies can level up beyond level 25.
