Challenge

You choose a creature that is visible to you within a range of 35ft by pointing at it. Yourself and the chosen creature are then trapped in a 35ft. dome that no magic,creature or item can enter/exit. Any other creatures except from the chosen one are pushed 5ft. away from the dome. If the selected creature is larger than 35ft. then the spell has no effect on it. The dome remains active until one of the two creatures inside the dome dies. 

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher the chosen creature has disadvantage on all of its attacks while in the dome
