I have (6 bases):
145 TG 5/9
147 Druid 5/9
141 SZ 5/9
100 Cupid 4/9
120 Champ or 80 Pally
I also use level 3 ornitopthers.
Spells i use:
- Ares frenzy
- Guardian Angel
31 shards: drop heroes at top army camp (slighty to the right) after the troops are killed SM targets my heroes, i take one hit then drop GA. After SM dies i drop ornithopters at the most right arrow towers. Use restauration when needed.
36 shards: Drop heroes at bottom army camp, when SM targets drop GA, heroes go to the corner and champ and succ target my heroes so i drop restauration, after champ and succ are killed my take care of the towers and TG's thunderstorm kills ninja and pally (hopefully). Use ornicopthers to clear arrow towers or to draw aggro if needed.
37 shards: https://www.youtube.com/watch?v=-kTOCldFTws
39 shards: Tried this out recently (not tested many times), i drop my heroes at the most right arrow tower, when SM targets heroes drop GA. After SM dies i drop ornicopters at the bottom left towers. Watch and use restauration when needed.
So basically i do dungeons were i can take out SM at the start and where my heroes are protected with GA. I started doing this when my heroes still were 7*. I know i have cupid but you have GR who seems awesome for dungeons. Hope it helps.
If anyone has better suggestions/tips i love to hear it.
