Spell factory +1 No. It's meant to only have one. You want ten spells dropped on your DE? Also that means shorter spell train time, so I think you just want to half your 4 spells train time.(4 was an example and 10 was for a max lv factory TH10)
dark elixir storage+1 Really? No the storage is enough. You just wanna save elixer upgrading the level 1 to level 2 instead of the level 3 to level 4.
