Chromatic Storm

Cold, fire, electricity, and poison culminate in your grasp and create a storm of elements on a creature within a range of 30 feet. The caster rolls 1d4 to determine the effect of the spell. 

1. Cold - The target creature must make a Strength saving throw. If the target passes there is no effect. On a fail, they take 8d6 cold damage, and are restrained by the ice. At the end of the targets turn, it may choose to break free of the ice. If they fail they lose their turn and remain in the ice enduring the restrained condition. Once this condition has been applied to this creature for the duration of the spell, it may no longer apply until recasted. 

2. Fire - The target must make a Dexterity saving throw. If a target passes there is no effect. If a target fails they take 8d6 fire damage and are caught on fire. A creature must spend a full turn dousing the flame, or taking 4d6 fire damage at the start of their turn. Once this condition has been applied to this creature for the duration of the spell, it may no longer apply until recasted. 

3. Electricity - The target must make a Wisdom saving throw. If the target passes there is no effect. If a target fails, they take 8d6 lightning damage, and are deafened for 1 minute. A target may remake this saving throw at the end of their turn every round. Once this condition has been applied to this creature for the duration of the spell, it may no longer apply until recasted. 

4. Poison - The target must make a Constitution. If the target passes nothing happens. If a target fails, they take 8d6 poison damage, and are under the effects of the poisoned condition for one minute. A target may remake their saving throw at the end of their turn. Once this condition has been applied to this creature for the duration of the spell, it may no longer apply until recasted. 

If a creature passes 3 consecutive saving throws, the spell immediately ends. After an effect is triggered, it may no longer be triggered again until the spell is recast. If you roll a d4 and have gotten the same number more than once, it will have no effect if it has already taken effect on a target. You may re roll the d4 again on the beginning of the targets turn.
