lvl 6 spell factory for new spell means 6 of these spells - lvl 5 spell means it multiplies the troop number by 6!
Therefore if you have 9 pekkas and one in cc, then 10 pekkas in the spell means 70 pekkas, then 70 pekkas in the next spell drop makes 490, at this rate
490 x 7 = 3430
3430 x 7 = 24010
24010 x 7 = 168070
168070 x 7 =
1176490 PEKKAS WHOLY ♥♥♥♥ LET'S ADD THIS TO THE GAME SO I CAN ATTACK SOMEONE WITH OVER 1 MILLION PEKKAS, THEN DEFEND AGAINST IT WHICH IS EVEN BETTER!!
Correct me if my logic is wrong, but that's what I picked up from that.
:P Couldn't wait to do barch raids with these spells
