Note4: The information given above represent my own experience with dragons over all Town hall Levels.Note3: Depending on the opponent's base, for TH7 and TH8 you may remove one dragon and exchange it for more 4 balloons.If there is an air defence missing or they are not well upgraded for the specific TH level, then the percentages may expand and you may aim for more than the Note2: The percentages shown in the table above assume the opponent have a decent arrangements and level of the air defence units.My only suggestion for dark spells is to use the Poison Spell for the CC. They can easily change target and move from their original spot, therefore I do not suggest using Haste Spells for them.
