I tried different things but failed, till i realized something- if you concentrate making forces on one sport fast, leaving enough mana to click on them once, you'll make them crush enemy gate fast. If you don't succeed in first wave, use bombs to slow down enemies on other places, or make things easier for your army. Of course, keep summoning at the same place you first summoned them. Also, use all 3 types on one passage at first, till you kill that gate.
Instructions for getting hard badge the easy way:
Don't buy heroes, just use current ones, and focus on Trainee Kirana. Pick magic oriented perks at the very start.
Under skills invest only in energy.
For Kirana, pick only magic use.
Items on Kirana for magic use boost, on other 2 support heroes lives.
When upgrading units focus on dmg.
Finish all the blue storyline quests on the bottom of the map.
I had some difficulties on some quests, but proper unit mixing helps. On most quests you just need Kirana.
Time wasted 43m: 21s. Good luck!
Aha! I need 3 pieces of water here, 2 there and 5 here, gotcha! :D
Nice game, challenging at times. I'd like to see water falling faster, not like at near 0G though :D
