Heat climbs by 1 per second within three blocks of lava and by 0.5 below y 40. Higher up and away from lava it drops by 1, in water by 2. Past 50 you get hungry, past 75 your pickaxe drags, at 100 you burn. Each piece of the Thermal set cuts the gain by 12.5%, Cooling Water takes 50 off, Ice Bread slows it for five minutes.
