Easy achievements , ALMIGHTY!!!!!!! BASE!!!!
Almighty allows you to use all abilties on your weapon without having to use charge attacks. Regular and charge attacks enable the Almighty abilty. To unlock the Almighty abilty for your weapon all you have to do is acquire all ingredients (treasures). In order to add Almighty to your weapon you must sacrifice a weapon that has ice 2, flame 2, slay 2, flash 2, bolt 2, might 2, brave 2, and absorb 2. After you have these abilities on a weapon you're willing to sacrifice go to upgrade skills in the customize weapon screen and select Almighty and choose the warrior that has the required weapona bilities. Then, sacrifice the weapon. After you've done that go to weapon upgrade and choose any warrior you wish to have this ability. Add it to their best weapon. After adding the ability to that weapon, start adding elements and other abilities to it. For example, you can have Ice 10, Bolt 10, Flash 10, Slay 10, Brave 10, Range 10, Agility 10, and might 10 on a weapon. there's no point in putting absorb on a weapon that has Almighty because it just continues to give you musou that you don't need. If you use your musou in any way you will not be able to use the Almighty ability until your musou gauge is full again.
