Ratfolk : Scurrying Swarmer question :)

[Lematou]

Hello,

First, I apologize for my english. It isn't my native language :)

So, I'm working on a character idea, a ratfolk cavalier. I'm trying to build a cavalier4/rogueX. And I need help to understand how the Scurrying Swarmer feat may trigger.

Does the feat triggers when mounted (as both the cavalier and her mount share the same square) ?

Or does the little cavalier have to dismount (and "hide" between the legs of his mount) to trigger Scurrying Swarmer ?

I use it while mounted. Though you only flank the creature your mount attacks.

You could Use it mounted or unmounted. If your mount has multiple attacks, you can have it attack multiple targets to gain flanking on more than 1 target.

I thank you both for your answers :) Ratfolks cavalier/rogue rejoice !

Just in case (when the cavalier is attacking the same target as the mount, with same reach for both) : as long as the flanking triggers, teamwork feats like Outflank and Precise Strike should also work, shouldn't they ? So do the sneak attack damages ?
