Reduce

Time: Slow Action Target: Self or a creature or object in Swinging Distance
Test: Mage Stat Save: Focus
Effect: Buff

If the target is willing or Fails a Focus Save, the target halves in size and its weight decreases by a factor of eight. This reduces the target's Size down by one category.

If the target is an object being worn or carried by a creature, the creature instead makes the Focus Save.

If the target is a creature:

• Everything the creature is wearing and carrying changes size with it. Any item dropped by the creature returns to normal size instantly.
• The creature has an Advantage on Edge Saves and on any Skill Test that would benefit from being smaller and more dexterous.
• The creature has a Disadvantage on Grit Saves and on any Skill Test that would be hurt by being smaller and physically weaker.
• The creature has a Disadvantage on all Abilities that require an Attack Test, but can always deal an extra 1 Damage if they get a Failing Score on the Attack Test.

Based on your Mage Stat Score:

• [..6] The target can make their Focus Save with an Advantage.
• [7..9] No Effect.
• [10..] The target must make their Focus Save with a Disadvantage.
