Re: Making dragons slightly tougher
Given that some snakes have it, Infravision makes sense for dragons, if you include Protected Sense so they don't blind themselves with their own fire.

Re: Making dragons slightly tougher
Pit vipers have very weak "heat vision" out to no more than 6'.
But it certainly fits dragons, thematically.

Re: Making dragons slightly tougher
Well, it doesn't have a range limit per se. It just has cruddy resolution (observed accuracy is about 5 degrees, which is about 1/300 the resolution of human vision).

Re: Making dragons slightly tougher
From the studies I read, they were incapable of recognizing prey right in front of them past that distance.
Even then they're using rather advanced processing to make out even that with all the inherent limitations of their method of heat vision.

Re: Making dragons slightly tougher
Of course, SM -1 snakes have ~1/22 to 1/100 the surface area, and thus most likely the light-gathering power, of SM +3 to +5 dragons. That corresponds to an effective range multiplier between ~4.6× and 10×, so even if snakes can recognize prey at only 2 yards, dragons should be able to manage 10 to 20 yards (equivalent to a Vision bonus equal to SM difference: +4 to +6).
Dragons also have better processing: Per 14-18 vs. a snake's Per 10 (equivalent to a further +4 to +8), for a range multiplier between ×5 and ×20. All in, between hardware and processing, I'd expect dragons with Infravision to be recognizing prey out at 50 to 400 yards even if they work exactly like big snakes, which is unlikely for fantasy monsters. However, dragons already get Night Vision 9. Read as light-gathering power, that's well beyond the +3 to +5 you'd expect relative to a SM 0 human, based on size alone. Depending on how you argue, you can justify another +3 to +6 with a suitably-constructed eye, so on average there's around +5 from that. The same construction may well benefit near-infrared vision and give another ~7×, justifying more like 70 to 150 yards with hardware alone – or around 300 to 3,000 yards with good processing. Average Per 10 humans with the +10 for "in plain sight" and no darkness modifiers have the same odds of seeing things at 100 yards, so I'd have no problem saying that draconic Infravision is simply Infravision without any weird limitations.

Re: Making dragons slightly tougher
Techniques and perks don't exist per se in the DFRPG. Some are hidden within the pricing of professional abilities, but in general they're not part of the game. That sort of finely sliced complexity is what GURPS is for.
