Ray Tian Zhi Shen

I've been in Ryan's sci-fi campaign for 3 years now. Most systems in his campaign are homebrew, and Ryan allows great flexibility in how players can use their spells. I played as a mythical knight who specializes in mind reading, water magic, and sword magic (like Gilgamesh from the Fate series).  With sound reasoning and right conditions, Ryan will allow you to do some insane stunts. For example, I could create a flood (almost like Bible-style) and clear out waves of enemies in an instant. However, the reason that I was allowed to do that was because I had absorbed a large amount of magic power from the planet in the prior expedition before the assault on the enemy's base. Because of his game designer background, you can expect plenty of balancing tweaks and changes to the system that will make your adventure a lot easier. I highly recommend Ryan as the DM to new players.
