Thought up a monster one night- the Toralusk. Its basically a large boar with magical scaly golden skin that snares weapons. All those weapons in its hide are testament to the hunters and warriors that have attempted to kill the beast and failed. The beast is very intelligent and can breathe smoke when enraged, but its greatest ability is to magically grow in size the more it is attacked. Every arrow that doesn't kill, and every spear that gets stuck in its hide makes the beast larger and larger, much to the dismay of the creature's opponents.
