Erratic Goliante is a Unique Monster in Xenoblade Chronicles that is a member of the Gogol family, and can be found at level 97 in front of the entrance to the Trader's Stopover at the Heavenly Window landmark in Tephra Cave. It can drop the Gogol Horns which are needed for the A Token of Friendship quest as well as the Colony 6 Reconstruction.
It has 2280 damage per hit of topple Spike Damage, therefore it is not a good idea to topple it unless the party has strong Spike Defence from gems and skill links.
