Magic Bolt stands still while it fires, with no more jitter. Fireball gathers fire at the tip of the staff and leaves it right on the push, with a ring of heat bursting out. Frost Nova leaves glittering rime and patches of cracked ice that slowly melt. Meteor has its own motion for calling down the sky and leaves a burning crater with a rim of embers that slowly cool. Blink leaves a violet afterimage where you vanished. Mana Shield has its own motion for raising the shield.
