You call upon the powers of Eldris, the god of ancient wisdom and future insights, to momentarily unshackle yourself from the linear flow of time. For the duration, you gain the ability to act twice during your turn. You can use your actions to attack, cast spells, use items, or do anything else that you would normally be able to do, effectively doubling your action economy.
However, this power comes at a cost. Every time you use an action while under the effects of Temporal Rend, you must make a Constitution saving throw with a DC equal to 15 or half the total damage you dealt during that action, whichever is higher. On a failed save, you immediately suffer 2d8 psychic damage as the strain of manipulating time takes its toll on your mind and body.
The spell ends if you lose concentration, or if you choose to end it as a free action during your turn. Once the spell ends, you suffer one level of exhaustion.
