I just reread the DH Book, and it states that the Ballistic Mechandrites are shoulder mounted. So question is how do you play that ? 2 Gun Mechandrites only, or up to the techpriests toughness bonus?

Up to the Toughness Bonus. If you were to follow that other logic, no Tech-Priest could have more than three mechadendrites. (2 on the shoulder, one on the sternum) I tend to follow the mounting guidelines more loosely, seeing the ones in the book as suggestions. (I had an NPC once who had mechadendrites mounted to her pelvis that could be concealed in her bionic legs.)

It really doesn't matter as you can only fire one. Firing one uses your reaction.

After the Errata you can fire one Mechandrite for an half action during your turn, or as a reaction. Also you have different weapons to choose from then, like a Flamer, Melter or Bolter.

im sorry curiosity is getting the best of me what mechandrites did she have in there?

I usualy take it as up the the TB although if i have if they pay for a best quality model they can carry two more than their TB

She was a Magos Biologis, so they were both medicae mechadendrites. It serves no real game purpose to have two, but she was a big fan of excess.

Ah, a Tech-adept wallowing in excess. Slaanesh will take her gladly... *CouGH* I mean, HERESY!

That same talent is available to Explorator characters in Rogue Trader. It's called the Machinator Array.

Ah sorry, i forgot to mention it. Of course im talking about a Secutor, no point in packing that firepower to a normal Techpriest.

I played him to Myrmidon rank ( Techpriest ), and i was allowed to use it, when we switched to Rouge Trader. Its just that our GM ruled out that Ballistic Mechandrites need to be shoulder mounted now

In RT I think you get Machinator Array the same rank or the next.
