if i'm hasted...can i 5' step back, cast a spell, and then as my partial action cast another spell (with casting time one action) and move another 5 feet? i do get a 5' step with my partial action right? that way i'd be 10 feet away from the fighter again so he couldn't full attack me and i'd still get two spells. i'm a noob. so pardon me if this has been asked 20 times before.
