# Charm of the Slayer One weapon in your possession becomes a [Dragon Slayer](3-Mechanics/CLI/items/dragon-slayer-xdmg.md) or [Giant Slayer](3-Mechanics/CLI/items/giant-slayer-xdmg.md) (DM's choice) for the next 9 days. The Charm then vanishes from you, and the weapon returns to normal. *Source: Dungeon Master's Guide (2024) p. 99*
