I've been wondering if there are spells in Pathfinder similar to the 3.5 spell Luminous Assassin, hopefully that do not suck (the original spell was the start of a grand idea, but the stats were horrible).
If there are not any spells like Luminous Assassin what would be a good starting point, should it be list based like summon monster I-IX?
I was thinking of using stats of the NPC in the NPC Codex. Perhaps using spell lvl x 2 as the CR of the creature summoned. No equipment can be transferred from the summoned creature. Obviously I'd need to come up with specific wording. I'm thinking the full spell casters summoned would be spell lvl x 2 - 2 as the CR for them. That means that they don't appear on the I list of "creatures."
So... are there any spells already done?
