Snow Rat is an Enemy in Dark Souls.
Snow Rat Information
A special type of Sewer Rat found exclusively in the Painted World of Aramis.Similar to the small sewer rats, with one huge difference: Snow Rats can inflict Toxin effect with its attacks whether or not they're blocked. About as aggressive as its more common cousin - that is to say, not very - but its attacks inflict toxic damage when aggravated (more lethal than the Sewer Rats' poison), so if you meet any kill them quickly.
- Since the area they appear in is infested by Engorged Zombie, you should be bringing poison protection - Spider Shield recommended. Most problematic when they appear in groups - use wide attacks to kill multiple rats at once, as they are easily staggered.
- Spear and shield or magic work best. They usually ignore you until you attack so just make sure to kill it quickly or just take 1-2 hits, block, rinse and repeat.
