Whats the point of upgrading the earthquake spell.
It is going to damage walls and buildings. However It is intended to be used for breaking walls.
Level 1 earthquake spell takes 4 spells for the walls to be destroyed, on the other hand the Level 4 earthquake spell takes 4 spells to do the same.
Strictly speaking of task of breaking walls.
dark elixir spent in the research = 30,000 + 60,000 + 90,000 = 180,000 Dark elixir.
also considering the cost(Dark elixir) increase per spell is from 125 to 180 = 55 dark elixir.
You spend 180,000 + 55 times number of spells created of dark elixir more than you could have spent without upgrading it
So basically you are paying more amount of dark elixir for doing same amount of damage to walls.
Is there any point in upgrading the earthquake spell ?
