guide for insane dungeun two
You don't need Mino but it really helps to have Santa Boom or Spirit Mage, as those two can clear buildings on the other side of the map.
The hardest hurdle that most F2P player will have to over come are 1-5 and 1-8.
For 1-5: Do NOT place snowstorm ahead of time. Place your troops on the left with GA and Frenzy, all the enemies heroes nearby will come toward you. Then place Snowstorm.
Now you have a bunch of heroes gather in one spot for easy PD stacking.
For 1-8: The best drop is at the bottom, not the left.
1) Meteor the Drac and 2 DK on the left along with some buildings.
2) Use Frenzy
3) Use Snow Storm on the magic towers (4) bottom
4) Drop your troops (tank first) 5) wait ~3s 6) Drop Guardian Angle
