I'd give it the creator's BAB, if only because it would be pretty useless at high levels otherwise. If you need to justify this in-game, say that the coglayer's increasing understanding of combat allows him to fine-tune the targeting servos for better accuracy, or some such technobabble. This does mean that a fighter/coglayer or a steamborg can make more accurate autoweapons than a coglayer of equivalent level; if this bothers you, say that it just uses half the character level (round down) as the BAB, regardless of class(es).Reese wrote:(from this thread) when you make a combination of steam powers that performs automatic attacks, what attack bonus, if any, does it use? for instance, if i used the repeating crossbow + automator + targetor + discriminator + voice command example from the book...is it using a straight +0 or the attack bonus of the creator/owner?
I've got a question, also: does that auto-crossbow require an animator, or not? The descriptions of Animator and Targeter say yes, the power list for the "Cover Fire" gadget says no. Personally, I'd say no: it sounds like a targeter includes the servos necessary to aim the weapon and does so by itself, so the automator's task list becomes "pull trigger, turn reloading crank, repeat."
I'd also say that you could leave out the voice command and control the weapon with a switch. This would make it a move action instead of a free action, which has some definite drawbacks.
