Anhur is missing storm domain. Surely an oversight back when the extra domains were put in since he is a mulhorandi deity or whatnot, as two of five portfolios are Thunder and Rain.
I suggest adding it :)
Actually I believe this is a bug, as this post (http://www.escapefromundeath.com/forums/showpost.php?p=238092&postcount=2) includes Anhur/Storm.
I have issued a proper bug report with the appropriate information here. (http://www.escapefromundeath.com/forums/showthread.php?p=335800#post335800)
