Sun Paraelemental
A sun paraelemental resembles a miniature sun with glowing red eyes and mouth. Their diameter is equal to their hit dice in feet. Sun paraelementals enjoy absorbing sunlight during the hottest parts of the day and burning things that block sunlight.

In combat, the sun paraelemental uses its heat rays to burn opponents with super heated air. These rays have a range equal to the sun paraelementals hit dice in feet. However, the paraelemental usually prefers to attack by emitting rays of light. It can release six different beams, each with its own effect:
Dark Red beam: inflicts 3d8 points of heat damage.
Red beam: inflicts 3d8 points of acid damage.
Red-Orange beam: inflicts 3d8 points of electrical damage.
Orange beam: inflicts 3d8 points of bludgeoning damage.
Orange-Yellow beam: inflicts 3d8 points of piercing damage.
Yellow beam: inflicts 3d8 points of cold damage.
Each beam is 1 foot wide and has a range equal to the Hit Dice of the paraelemental in tens of yards. The creature can emit only one beam each round, but it can otherwise use the rays as often as it likes. The beams don’t automatically hit their target; the paraelemental must make an attack roll.Sun paraelementals may forgo their attack and instead flare brightly and attempt to blind their foes. Foes looking at the sun paraelemental when is flares must succeed at a saving throw vs death magic or be blinded for 1d10 days. Sun paraelementals can be struck only by +2 or better weapons, and they’re immune to the effects of heat and flame.
