Still working on Pelacor Conjurer for the time being. @half-fast
I really don't like these "pick one" questions, as limiting a generalist to a specific creates a quandary I think most of the summoners bring something new and needed to their respective splinters. The only one I'd exclude as my favorite is Thaddius Brood as his abilities are still far overshadowed by Owster. That said, he may come in to his own after:
- they add modern
- dice falls off the modern list
Until that time though I find Owster as a better choice.
