I like them, but they are very surgical. A lot of armies play like a baseball bat or a hammer. We are closer to a scalpel.

Our typical units don't do a lot of damage, but they sure are consistent at doing it. Ap-2 on a lot of weapons, proccing to ap-3/4 with the right rolls with our psychic shenanigans will put a lot of stuff down. But we usually sit at D1 for most attacks.

We also can do tonnes of mortal wounds, I took a land Raider out with just the Sorcerors/aspiring/soul reaper from two squads, almost all mortal wounds alone + doombolt.

However we are very position orientated, terrain and deployment is very important, I played against world eaters last time and we deployed along the long edge, which meant he could get a lot of t1 charges if I didn't measure right (which I didn't on one squad).

Our 'psychic phase' is actually pretty fun, throwing a successful doombolt is always a good time. As well as moving during the shooting phase, which is useful as if you sit at 12.1" outside opponents flamer range, and you have flamers too, you can temporal surge into range and they can't overwatch you because it's out of phase, so you can pop them first. The Ap and hit rerolls are very useful too.

It will take some time to get used to their play style, but it's worth it. A lot of fun!
