• Transformation. The target makes a Wisdom saving throw, on a failure it is transformed into a Tiny harmless creature. You choose it's appearance, while in this form it cannot make attacks or cast spells. The creature reverts to its normal form if it takes any damage or when your Curse end on it, it also repeats the save at the end of each turn reverting to its normal form on a success.
• Weightlessness. The target makes a Constitution saving throw, on a failure it becomes weightless for the duration of your Curse. The target's jump distance is doubled, and if it is subject to forced movement it moves twice as far as normal. In addition, the target does not fall a the end of its jump/forced movement, but instead remains hovering in space. When your Curse ends the target floats down harmlessly to the ground. If the target has a fly speed it can fly normally while hovering weightlessly. 
• Sudden Aging. The target makes a Charisma saving throw, on a failure it appears to rapidly age. The target's movement speeds are reduced by half, and it has disadvantage on melee attack rolls, and Strength and Dexterity saving throws for the duration of your Curse. 

You can use this ability 3 times, regaining all uses when you finish a long rest. You can expend one of your Pact Magic spellslots to regain a use of this ability (no action required).

Level 14: Irresistible Hexes
