Cryptic Command

When you cast this spell, choose two of the following effects:

• Counter - You attempt to interrupt a creature in the process of casting a spell. If the creature is casting a spell is of 4th level or lower, its spell fails and it has no effect. If it is of 5th level or higher, make an ability check using your spellcasting ability. The DC equals 10 + the spell’s level. On a success, the creature’s spell fails and has no effect.
• Rebuke - You attempt to blast an attacking foe away. One creature within 10 feet of you must make a Strength saving throw. On a failed save, the target is pushed 30 feet away from you and falls prone. On a success, the target is pushed 15 feet away from you. This movement does not result in opportunity attacks.
• Fatigue -  You cast the spell sleep at 3rd level as a part of this spell, without needing to expend an additional spell slot. This does not count as you casting an extra spell.
• Prepare - Choose one spell that you know, but do not already have prepared. You may add it to your list of currently prepared spells for one minute, or swap it with one of your currently prepared spells.

This spell must be learned in game.
