As of patch 1.10, polar ray can score a critical on a 20 threat roll.
With at least 3 levels in Arcane Scholar of Candlekeep this spell can be empowered (treating it as a level 9 spell), causing it to do 38d6 points of damage. On a critical hit, it does a whopping 76d6 points of damage. Against a Red Dragon with 50% cold weakness, this would do a whopping 114d6 points of damage! Since that does an average of 399 points of damage and a red dragon has 361 HP, this is the only spell in the entire game that has a possibility of instantly killing a red dragon out of sheer damage.
