Paths of Prestige is on PFSRD.com so I was having a look through at all the PrCs. I quite liked a few of them (Lantern Bearer, Hellknight Signifier) but I've been really looking forward to the Winter Witch.
However, I noticed that

Hyperboreal Patronage
A winter witch's patron reveals an icy aspect, granting her the following spells as patron spells at the following class levels:
1st—ice spears, 3rd—wall of ice, 5th—icy prison, 7th—freezing sphere, 9th—fire storm (deals cold damage instead of fire).
Firestorm, dealing cold damage but it doesn't have the cold descriptor and it still has the fire descriptor. Ice Magic blocks Winter Witches from learning and casting fire spells. So not only does it not get a buff but you can't use it? (This is the same line of reasoning behind Crossblooded Sorcerers) Or is this a copy error from PFSRD? I don't have the book so I wasn't sure.
tl;dr Can't use Firestorm with Ice Magic?
