There's no point to an ice Gal Rod since a Nep or Evil Rod with Ult Buster will do nearly identical damage in the only place you mob with ice, and those will of course, do more with Barantsion and be completely hassle-free.
Personally I wouldn't deal with it for Dark either unless you already had one grinded/affixed before Ares stones became a thing. Better off feeding it to Austere and doing the relatively painless Ares grind if you want a good dark rod but can't manage Austere.
