You may set the resizer to either enlarge or reduce the target's size. When shot at a creature or object (neither worn nor carried), they have the opportunity to make a CON saving throw (if they are unwilling). If they pass this saving throw, no effect takes place.   If a creature is targeted, everything they are wearing and carrying scales in size with the creature. Any item dropped by an affected creature is returned to normal size at once.   Enlarge. The target's size doubles in all dimensions, and its weight is multiplied by a factor of eight. Growth increases the size category by one (i.e. from medium to large). If there is not enough room in the location for growth to take place, the creature or object attains the largest possible size in that location. For the duration of the effect, the target has advantage on STR checks and saving throws. It also does an additional 1d4 damage with melee weapons.   Reduce. The target's size is halved in all dimensions, and weight reduced by a factor of eight. This reduction reduces the size category by one (i.e. medium to small). For the duration of the effect, the target has disadvantage on a STR checks and saving throws. The weapons are also shrinked, and deal 1d4 reduced damage (cannot be below 1).
