But before the upgrading process completes, 2 lightning spells were being cooked in the spell factory which were level 1 (total cost 30000 elixirs). So when the Lab finishes the upgrading, My spells (which were being cooked in the spell factory) also become Level 2 spells! But Level 2 spell costs 16500 Elixirs (Means 33000 elixirs for 2 spells)!
That means, If now i cancel the spell cooking in the factory, I will get 33000 elixirs back in my storage, but I spent only 30000 elixirs at first!
3000 Elixirs come from nowhere!
So think, how much can u get for free when the Dragon upgardes to level 5 from level 4, or Rage spell from level 3 to level 4!
