Re: 7: Hole In the Wall Pub (OOCs)
I suspect Endure Elements' temperature range was meant to cover the range found on Earth, which are all natural temperatures. Hottest temperature recorded on Earth was 134 degrees in Death Valley in 1931, so Endure Elements covers that. But, we're talking about a fantasy world where magic is real, so there can be places where the temperature might exceed the 140 mark.
What Endure Elements is meant to do is to protect you from the collateral issues of high heat or extreme cold--thirst, dehydration, searing your lungs from the hot air, etc. Once you enter an area where the temperature would be higher than that, the protect doesn't end but it's not going to be all encompassing any more.
Lava flows can get as hot as 1,600 degrees while magma can reach 2,100 degrees.
So, yes, getting within 30 feet of the magma will cause damage. How much depends on other factors: angle of exposure, air flow, the reflectiveness of what you are wearing, toxic fumes, and the actual temperature. The damage rises exponentially as you get closer. Within 30 feet, 4 points of fire damage per round; within 20 feet, 16 points of damage per round and 2nd degree burns on exposed skin; within 10 feet, 64 points of damage per round; within 5 feet, 250 points of fire damage per round.
