As far as I've seen in my many years of playing D&D, it's not possible to have feats taken away from you, unless the DM house-rules it. You get toughness from "Two-Blade style" for free, but just because you retrain your style, shouldn't mean you get that feat taken away from you. It would be permanently taking away at least 5 (number depends on level)
hit points away from your character, which isn't possible to do by retraining.

Except, you know, by taking the feat and then retraining it. Which is basically what you're doing here.

Nope. Once you get a feat, you get the feat. It specifically says, "You get toughness as a bonus feat" for taking two-blade style. Feats can't be taken away by retraining, unless the DM says so. Not to mention the fact that you can't retrain class features, so why does it matter?

Or unless the book says so. Which it does. Like Sithobi said.

Maybe not taken away, but even in 3,5 you could replace them. Retraining. It was in PHB2 if I recall correctly.



There was that of course.

Does mean that you have the option of retraining the feat you gain from your combat path? For example, could a character take the archery combat style and then retrain Defensive Mobility? This could be really useful if someone wanted to play a Battlefield Archer or Beast Stalker, but didn't really want Defensive Mobility. I'm pretty sure I prefer Toughness over Defensive Mobility even for an archer. So would it be possible to swap the feats at level 2 through retraining? (I wouldn't get any other benefit of the Two-weapon fighting style, but I'd have Toughness and access to Battlefield Archer or Beast Stalker).

Show me the exact page number and paragraph where it says you can lose feats, and I'll believe you. And when I say "lose", I mean actually lose it, not retrain and/or replace it.



Yes, you can retrain / replace them, but if it were ever possible to "retrain" a class feature, you technically wouldn't be "retraining" the bonus feat.




There's always been that. Like I said, most of this stuff is left up to the DM, except the things the PHB says you can actually retrain. But even then, the DM could house-rule and say "no retraining whatsoever," if and when he wanted.

As long as the PHB says you can retrain feats, then yes, you can technically retrain a feat you get from a class feature. Honestly, defensive mobility isn't one of the best, but definitely not the worst feat. So, in my opinion, I'd take the archer style, take the bonus Defensive Mobility, then just take Toughness as your first level feat. This way, you have both, so you can roam the battlefield more freely with higher AC against o.a. and more hit points.

EDIT:Sorry I completely told you wrong on the earlier paragraph. You can't retrain class feature feats, so your best bet is to stick with one ranger style or the other, then take the bonus feat you didn't get as your first level feat instead.

If you could retrain class features, there's no reason why retraining a class feature wouldn't retrain the feat that goes with it, because the feat is part of the class feature.

Like I told Core, show me page numbers and paragraphs or your words mean nothing. Not trying to be mean, but you are trying to argue a point that doesn't make sense.

There is no page number because it's part of a theoretical house rule. However, logically, losing a class feature causes you to lose the entire class feature, not just part of it.
