Aww, come on!
You guys...Camarath did so much work and thought on this, and you're criticizing his spelling. How rong of you!
Seriously though, thank you, Camarath, the monkey truly appreciates this. It'll help a lot.
While I'm writing here, I have two questions:
Can Tieflings see in the darkness they create? While he does have darkvision, I know he can't see in magical darkness. However, he argued that it wouldn't make sense that he couldn't see in his own darkness. Yet I can find no mention that he can, anywhere. Plus, sorcerors/wizards who cast darkness can't see in it. Obviously he loves to sneak attack foes within his darkness, but he doesn't do it that often because the rest of the group is at a disadvantage. And would he be able to dismiss the darkness? Any thoughts on this? I'm just in the dark about it...ooooh...sorry.
The other question is regarding the ranger's favored enemy. He made his favored enemy Devils, as he is "reformed," being neutral good, and making his arch-enemy his naaasty half-fiend father (who I am making one of the main enemies of the campaign - and I'm thinking of "grandpa" being one of the head honchos in Hell/Baator). Now, does having favored enemy as Devils mean that he can recognize any demon he comes across, as well as their powers? Like (in game here), "Ahhh, that's a Barbazu. It can attack with it's beard and possibly give you a disease called devil chills, it can cause bleeding wounds, etc etc etc..." How much can a Ranger/Rogue/Tiefling with a Fiendish Bloodline know about devils and demons (I think demons would be the next favored enemy). I can find no mention of this in the PHB or DMG, maybe somewhere else, like one of the builder books? I can see how he should be able to recognize them for who they are, since they are his favored enemy and "know thy enemy," but where's the limit?
Thanks everyone again for all your advice.
PS - The monkey's favored enemy is bad drivers.
