Quick question:

What are the 5e options to resist, endure, protect yourself against or plain ignore conditions like snowstorms, baking sun, avalanches, lava pools, icy water, extreme altitudes, and other environmental extremes?

I would like to build a handy "complete index" that covers all possible equipment, class features, spells, magic items etc that a DM should be aware of before trying to build an adventure where the environment itself is supposed to be a challenge?

I'm especially interested in low level options.

Any comparisons to d20/3E would also be welcome. For instance, 3e offered a spell called Endure Elements which pretty much trivialized any desert or winter challenge all by itself.

Thanks :)
