Nagritch is selling a scroll for a 9th level spell, "Tide of Battle." The spell claims to be a sorcerer/wizard spell, but won't scribe into a wizard's spellbook. The message given is 'You can only learn arcane spells.'
I presume this scroll isn't what it says it is and should be removed from the bookstore? It was kinda pricy too >.>
It is what it says it is; it cannot be learnt because the spell was removed as a spell players can learn. The spell itself was added in HoTU, and can be used from a scroll or an item.
It is misleading for it to be sold in a shop though, and should probably be removed.
