Weapons dropped by Grenade are slightly stronger than most weapons (they have a Damage Constant of 18, while any otherwise-identical weapon has a Damage Constant of 16); a trait shared with Bomb and Puroboros, but not found in Bomb King or any enemy outside the Bomb species.
When fighting a single Grenade, with two Grats, if the player uses any Blizzard spell with Lulu, the game will glitch, and the Grenade will not grow.
Grenades boast an exemplary magic defense stat, rendering almost all magic virtually useless at the time they are encountered despite a weakness to the ice element. Attempting to trounce it with this method will likely allow the Grenade to use Self-Destruct, as it always does after surviving three hits. Parties should engage a more foolproof method by tackling the menace with Icestrike weapons equipped to physically buff characters—Auron proves most valuable. If the party wishes to capture the Grenade for the Monster Arena, whittling down its health with this method should suffice. Only stronger characters such as Auron will ensure a kill in three hits during the time in which the party initially encounters Grenades on Mt. Gagazet.
