Anti-CC potion. Is this a viable option to prevent chain-cc or similar? I've not seen anyone mention this at all.

It'll break your frozen/cc status, yes... but in the chain-cc scenario, you'll be back frozen again after that 1 second of unstoppable has expired.

Still, better than nothing. My barbarian pre-season had two cc-break skills and still couldn't fight multiple cold-enchanted elites without being constantly frozen. Maybe a third in elixir form may have given me the edge I needed to kill them?
