Lesser Paraelemental of Rain

Second edition AD&D failed to make paraelementals for Dark Sun, so I will be creating some. I've decided to start with the lesser paraelementals and eventually get to the greater paraelementals.
I'm continuing with the lesser paraelemental of rain. Feedback is welcome.

Lesser Rain Paraelemental
A lesser rain paraelemental resembles rain drops in a vaguely humanoid shape with lighting running through it. Lesser rain paraelementals enjoy watering plants and electrocuting those who harm plants.
Combat
In combat, the lesser rain paraelemental uses its lightning bolts to harm its enemies. These rays have a range equal to the lesser rain paraelementals hit dice in yards. These lightning bolts may jump between targets that are using metal weapons or wearing metal armor. A target within a number of feet equal to the hit dice of the lesser rain paraelemental, using metal weapons or wearing metal armor, must make a saving throw vs breath weapon or take the same amount of damage as the primary target.
Lesser rain paraelementals can be struck only by +1 or better weapons, and they’re immune to the effects of cold and lightning. If wounded in some way, a lesser rain paraelemental finds succor in rainy environments. When in contact with natural rain, it automatically heals 1d4 hit points per round, up to its normal maximum.
All damage against water or air based creatures is automatically halved. In addition, lesser rain paraelementals take 2 points of damage for each round they are in direct sunlight.
