Endure Heat

Even though Sorcerers might be serving the fire, it is still very deadly to them, especially lava is a huge threat.

With Endure Heat, the Sorcerer creates a blue fiels that protects its caster from the heat effects of the lava, meaning that the Sorcerer can walk over the solid, orange lave without any ill-effects for 2-3 minutes, opening up interesting shortcuts. However, this only counts for solid lava. The liquid yellow lava is still deadly and will swallow up the sorcerer without mercy!

Also this only works against lava. For protection against magical fire attacks, see Armor of Flames.
