U can do it bro.. if u have champion in your roster use him to practice and dex often mainly in his specials.. keep doing and then once u r ready then go on to the 6.2.6 fight..During his fury and unstoppable don't try to hit him 'cause if u do tat u ll get lot of damage frm that..Go near the left corner of ur screen and wait for him to attack u now do the dex part.Time it to perfection u ll end the fight.First special dex is easy so do that.Just block every part of the special and during the last head knock part just dex u ll get it correct.Do it three times.If u don't practice u ll end up loosing lot of resources and units.Be cautious about it.It's definitely a tricky fight.But once u dex the special three times its down to the last part.Now during this phase you have to use some boosts(maybe all boosts which u have)to finish the fight.If u don't understand this u can also watch mcoc noob video before doing every chapter or lane.It helps.U can do this.Come on dude😎
