I often wonder what it is like to play a tech-priest, So i've been looking into it. It seems to be as confusing as a psyker with all the extra things you have to take into consideration. Now, Tech-Priest obviously have a very important role in a group, repairing and dismantling nouns, but what do they do for combat? I know that they have their las-pistol arm and they get a desent bit of weapon training in las. This is all good, but can tech-priest hold their own in heavy combat or do they have more of a support role using servo skulls and other mechanized things to fight for them.
On top of that, the 1d10 extra tools? what extra bits and tools can they be? Last but not least, can anyone who has played with or as a tech-priest please give me some advise? (for those keeping up iam play 3 differn't campaigns with 3 different groups and character)
