All-Or-Nothing Coin

Once per day, Instead of rolling a D20, You may flip a coin (1d2, 1 = Heads, 2= Tails). Heads = Critical success (20), Tail = Critical fail (1)

Curse Of Sore Loss: If a Critical fail is flipped on an attack roll, The attack is diverted to a random friendly target within range, If no friendly targets are present, You become the target, If a Critical fail is flipped on a Saving throw, Take double damage on the effect, If the effect is non-damaging, Double the duration of the effect.
