Champ

To cast this spell the caster must flap their arms up and down while jumping in front of the rock, paper, and the scissors, while chanting "champ" 3 times. After this, the caster CANNOT BE BEAT EVER in a 'rock, paper scissors' match so long as the spell is in effect. The caster may put out whatever they choose and anyone who is challenging them must throw out the losing option, regardless of their intent. 

This spell is completley undetectable by detection spells and cannot be disspelled until the effect ends. No creature regardless of immunities or resistances can lessen the effects that this spell grants. Additionally, if the caster uses either a rock, a sheet of paper, or scissors to perform an attack or an action, they are guaranteed to succeed provided the DM approves of the action.

If the caster wins 'rock, paper scissors' 10 times before the spell ends, the duration is reset. As well, while the spell is in effect, the caster cannot drop below 1 hp, due to the absolute victory they possess in 'rock, paper, scissors' matches.
