Elasticity

You endow your body with rubber like properties allowing enhanced flexibility fueled by magic. Until the spell ends, you can’t cast spells, and you gain the following benefits:

• You have advantage on acrobatics and sleight of hand checks.
• When you attack a target with a melee attack, your reach increases by 10ft.
• You have resistance against bludgeoning damage, and vulnerability to cold damage.
• You have proficiency in Dexterity and Constitution saving throws.
• You can attack twice, instead of once, when you take the Attack action on your turn. You ignore this benefit if you already have a feature, like Extra Attack, that gives you extra attacks.
• You count as one size larger when grappling, and one size smaller when entering other creatures spaces.

Immediately after the spell ends, you must succeed on a DC 15 Constitution saving throw or suffer one level of exhaustion.
