Body Slam is a recurring skill in the Dragon Quest series. Upon use, it attempts to reduce both the user and target's HP by around 80%, and utilizes an foe's resistance to whack to calculate accuracy. Be wary of using this skill, as the player will still take damage even if they miss their target.
Body Slam is learned by several monster companions:
Body slam can only be learned by Ruff at level 6, possibly due to fan criticism of the skill and the removal of the Merchant vocation. In the 3DS version, Body Slam can be learned by the Sailor vocation at the second rank.
This ability is learned with 48 skill points invested into Courage skill. It is very useful for Quests that require a character to be at low health, giving it some added functionality.
