So bear with me, I'm trying to build a character around a specific, obscure racial feat. Thri-Kreen Shooter allows a Thri-Kreen character to wield a hand crossbow in their lower arms if they are wielding a melee weapon in their upper arms.
My character is a ranger, MC rogue to pick up the two-fisted shooter feat, which allows you to fire your hand crossbow when you make a critical hit. So let's say my thri-kreen is holding a superior crossbow in his upper arms, wearing some kind of weapon that leaves his hand free (spiked gauntlet, wrist-razors or some other free-hand weapon) as well- he can still load and fire his superior crossbow with the hand that has the melee weapon, correct?
Now, obviously, when holding his superior crossbow, the spiked gauntlet/wrist razor does not count as "wielded". However, in the course of one turn, let's say he fires that superior crossbow, gets a critical hit, then lets go of the crossbow with his other hand as a free action- that would make the gauntlet/wrist razor "wielded", right, allowing him to then fire his hand crossbow?
