This brief PDF has some really good ideas for spells, and for the price I can't help but recommend it. However, note that text is confusing in places, so this will need some interpretation from the GM. The first place this is apparent is in the class spell lists. The hunter class description says that the hunter chooses spells from a combination of the druid and ranger spell lists, using the lower spell level if a spell appears on both lists; but the hunter here is given its own spell list that does not adhere to this rule. The warpriest class description says that the warpriest uses the cleric spell list, but the warpriest here is given its own separate spell list. And while it's a nice touch that the elementalist wizard school spell is identified, it is odd that the spell level changes for the specialist. Additionally, a lot of the spell text seems incomplete. For example, on a successful hit, twisting shot continues to deal damage for 1 round/level of the spellcaster as the arrow or other ammunition continues to twist in the wound. It seems like the target should be able to end this damage by taking some kind of action to remove the arrow. With many little details like this, it seems like this document would have benefited from another round of editing with a rules expert before going to print.
