Solar Sponge is a soak mutation which gives resistance against burn, radiation, and acid damage. It also lets you heal when on fire or very hot (healing is determined how hot you are/degree of fire), and gives a maximum bonus of +2 to Brawn/Brains while in the sun
Solar Sponge can be found at ground zero, in the Wasteland
This mutation grants:
+1-3 burn resistance +2-2 radiation resistance +2-3 laser resistance Healing effect when on fire or very hot +2 to Brawn/Brains when in the sun
The heal effect on fire is nice. You can go stand in the orphan furnace and live, as it will deal damage but then heal you by very high amounts, enough to offset the damage.
You get a total of 3-6 radiation resistance which is pretty nice.
Takes up a soak slot.
