I want to add two new spells to my game. Probably more eventually, but for now I just want to add two.
Conjure Gargoyle and Conjure Shadow.
Now, for the most part, I figure I'm just going to be cribbing from Conjure Elemental, but I'm not sure what level to set these at. I mean, if I was absolutely sure my PCs would never get a hold of them, it wouldn't matter, but in case I am overwhelmed by generosity, I was wondering what folks thought a good method of gauging the level would be. I was thinking of calculating the XP value of the elementals, and adjusting the levels of my new spells based on that. But, Conjure Elemental is fifth available at ninth? I'm not so where Shadow and Gargoyle should fall before that... Certainly no sooner than third, right?
I'm rambling; I guess I'm just wondering who else has created new Conjure [monster] spells based on the Conjure Elemental spell, and wondering about your method and how successful they were.
