A 1st level slot allows the caster to change his direction once, and a 2nd level slot allows him to jump over medium or smaller obstacles. Additionally, the spending of spell slots and a material component (Pinch of salt, handful of rice, snow,...) to leave a trail of ice that causes units that move over it to take a dexterity saving throw (DC 5+Caster level times the level of the spell slot), becoming prone on a fail or having disadvantage on attack throws on a success.
