Thanks fot sharing your video. According to this post:
Ninja heores charge mana at this rate (without troops)
x1 charge - 5 tiles
x2 charge - 10 tiles
x3 charge - 15 tiles
But according to your video, you sent 3 tiles, then 5 more (8 in total, first charge), and then 4 more (12 in total but no second charge!).
Does this mean that ninja mana speed is set to very fast, so every charge requieres 6.5 tiles?
That would mean:
x1 charge - 6.5 tiles
x2 charge - 13 tiles
x3 charge - 19.5 tiles
Is this correct?
