So I am starting a new character in an ongoing campaign and I was going to do a Chain Armor + Spiked Chains dual wield trip tank deal but I decided to see what other reach type weapons might be available (due to not liking the chain armor penalties and also for RP purposes I didn't like the look of the armor....) and I thought of a Snake Sword (think Ivy from Soul Calibur) and then I found the 3.5 variant Snake Sword and my DM approved it and I'm just curious how the AoO works for that.
I was reading a few different movement based threads and such online and it said on one that moving from a threatened square is of course an AoO so I am curious:
If I threaten 15ft in every direction, does that mean that them moving from say my 15' threat square to my 10' threat square trigger an AoO?
