Monkey Paw

You've had incredible luck since childhood, but those lucks didn't bring you happiness. You have traits that seem to take luck from others, making everyone around you misfortune.

• When a creature is within 25 feet of you, that creature gains a -1 penalty on its ability checks, attack rolls and saving throws against you. If the targeted creature is an ally,  that creature also gains a -1 penalty on its ability checks, attack rolls and saving throws against their enemy. A targeted creature carrying a Stone of Good Luck (Luckstone) or Luck Blade is unaffected by this feature.
• For every creature that isn’t carrying Stone of Good Luck (Luckstone) or Luck Blade within 10 feet of you, you gain a +1 bonus on ability checks, attack rolls, and saving throws to a maximum of +3.
• When an ally within 60 feet of you (including yourself) rolls a 1 on a d20 dice, that creature takes 1d4 damage (the damage type depends on the action that the creature trying to do. For example, a creature takes bludgeoning damage while doing an Acrobatics check, or your Faerie Fire explodes while rolling a 1 on a Constitution saving throw and take fire damage.) If the target creature is within your sight, you must succeed a Wisdom saving throw of DC 17 or you will have disadvantage on your ability checks, attack rolls, and saving throws in the next 18 seconds (3 turns).

If you are carrying a Stone of Ill Luck, this ability and the item will cease to function until you take it off.
