Playing the new beta on steam I have noticed a weird thing: playing as an high elf druid I used a Nether Bolt on a Wererat and I noticed that "The wererat is badly injured by the icy blast" (see attachment). I thought that only fire creatures has this kind of vulnerability, and anyway I can't see a reason why a wererat should be especially vulnerable to cold attacks.
Has anybody noticed a similar behaviour before? Should I file a bug report?
