Attacking with Ray of Frost now creates a Frost surface and can instantly knock targets prone. If there is any blood in the area - and there almost always is if you're using melee attacks - it freezes a wide area of blood, which can also inadvertently cause creatures near the one targeted to also fall. Or worse yet, the targeted creature can make their Dex save and your ally can fail.
Acid Splash now inflicts -2 AC and creates puddles which also inflict -2 AC and also last forever. -2 AC is a +10% chance to be hit. Not being hit, but merely standing in an acid puddle inflicts a creature with the -2 AC, because apparently all attacks are targeting the bottom of your boots.
