Why don't people with aura have limited cold residents?

[Spinoirr]

Climate protection: One's Aura can protect from cold weather, as shown by Team RWBY and others walking through a snowstorm in the mountains of Anima with thin clothing and showing no discomfort. As with combat damage, extreme weather will deplete one's Aura eventually, which required the group to seek shelter from the elements at Brunswick Farms. Weiss Schnee's aura had dropped to low levels and she was beginning to shiver from the cold as they entered the farmhouse.

That means as long as ones aura isnt low or down you have cold reiance with aura

Because no one has bothered to add it, they should have some heat resistance too seeing as they can take a dip in steam and lava and walk away no worse for wear

 

[Spinoirr]

Yeah

Bump

Also ruby probably should have limited residents to willpower manipulation

If there Aura protects them from the cold and heat then resistance to hot/cold temperatures is fine.

Why would Ruby have resistance to Willpower Manipulation?, Just asking.

When used on the apathy a single flash flash momently broke their power. She also shown some level of reissuance to the Grimms ability
