I beat mammoth second try, Use poision till hes at 9 damage, he'll take 10k damage every turn pluse the other damage you deal. I used the sol spear for matt and fire attacks for lance and nat
@skyspanner I was to, make sure you don't use the limit breaks on tiny enimies, use when you find the rock, also have revive and group heal for natt(You really need this) Lancecs limit break is 50% bomb so it's super effective
