User blog comment:BannedLagiacrus/Monster Hunter Frontier: New World 6.0's Flagship Monster, Chramine!/@comment-6050823-20140724171609

To let you guys know, both of them use their Slime in different ways from each other. Chramine(New World) uses it in both an offensive and aggressive way while Mephitic Gypceros uses in a sort of defensive way but also in a combo happy attack way.

When Mephitic Gypceros spits its Slime on the ground or a wall and it explodes, it will leave a foul gas behind that can give hunters the Soiled but in Rage Mode it leaves behind a puddle of poison. Unlike Gypceros, a Shock Trap can be used on but its risky because it will drool Slime from its mouth and it will also emit a foul gas, much like Congalala in a Pitfall Trap. It does have one special thing that set it apart from the other Gypceros Species but that what is your guess.

Chramine has changed quite a lot but I won't say how lol!
