Well after having so many potions and books and hammer the only thing which I am missing is a "BOOK OF BASE or WAR BASE" which will allow our base to be maxed for a limited time. If its for regular war or league war it will activate when the enemy is attacks that particular base provided I used that potion or book on my village. It will also help everyone to gain experience to attack max base which helps to enhance skill set. Plz share your views and pardon my bad English.
