So I'm a little confused about how they work.
So the first one, Crane Style:
"Benefit: You take only a –2 penalty on attack rolls for fighting defensively. While using this style and fighting defensively or using the total defense action, you gain an additional +1 dodge bonus to your Armor Class."
Explained (is this right): When fighting defensively with this stance active I take a -2 penalty on attack rolls and gain a +3 dodge bonus to AC (+2 for typical fighting defensively and an additional +1 as noted in the feat).
Now the second feat, Crane Wing:
"Benefit: Once per round, when fighting defensively with at least one hand free, you can designate a single opponent you can see. You receive a +2 dodge bonus to AC against that opponent for one round. If you using the total defense action instead, you can deflect one melee attack that would normally hit you. An attack so deflected deals no damage and has no other effect (instead treat it as a miss). You do not expend an action when using this feat, but you must be aware of the attack and not flat-footed."
Explained (is this right): When fighting defensively with this stance active I take a -2 penalty on attack rolls and gain a +5 (do these stance feats stack?) dodge bonus to AC against one designated opponent. Against opponents not designated I gain a +3 dodge bonus.
Is this right, do the feats stack like that?
Would I need to be a master of many styles monk to use "Crane Style" and "Crane Wing" at the same time. Or if I am this style of monk can I use both of those (because they stack?) and another style at the same time?
Thanks for your help!
You only need Master of Many styles if you are mixing combat styles. You are not as Crane Style, Crane Wing, and Crane Riposte are all part of Crane; each additional feat just adds an extra bonus while using the original style feat.
So yes, if you have those two feats and have Crane style active, when you fight defensively you take -2 hit for +3 AC +2 additional AC versus one target. Dodge bonuses always stack btw and also if you have 3 ranks in acrobatics the AC bonus for fighting defensively also increases by 1, so you would have a +4 AC not including the AC against the one enemy.
