Adverse weather does not bother you. Regardless of your clothing or lack thereof, you’re essentially immune to the effects of exposure to harsh climates, as described in Mage 20, p. 435. You still need to eat, drink, and breathe – this Merit won’t save you from starvation or suffocation – and climate-based obsta­ cles (fog, high winds, snowdrifts, ice, etc.) hinder you as badly as they’ll hinder anybody else. Aside from outright attacks by the elements, however, you remain untouched by extremes of temperature and climate. You might not always be comfortable, but you’ll survive.
