So, as we all know flying things suck when you're fighting them. Among other things, they get to ignore all the lovely ground-effect things that create difficult terrain - however I *think* that the feat Difficult Swings might be able to get around this.
Since it's a weapon mastery feat, you have to either have that class feature or take the Martial Focus feat to qualify for it, but
Quote:
Difficult Swings (Weapon Mastery)
You can force foes to move cautiously when near you.
Prerequisites: Base attack bonus +5, weapon training
class feature with a melee weapon.
Benefit: When you make a full attack with an appropriate
melee weapon, you can force creatures to treat squares
adjacent to you as difficult terrain until the beginning of
your next turn. You can choose to allow any creature you
are aware of to ignore the difficult terrain you effectively
create with this feat.
Now, there are instances where there CAN be difficult terrain in the air - rooms filled with chains come to mind - and this would seem to be doing the same idea. The creature isn't stuck in something, they just have to be super caution when moving, hence "difficult terrain"
Am I reading this right? I don't want to be all gung-ho at a table with it and not have some more peoples opinions/etc to back me up.
