OK, there were some errors. Some questions and some other fixes to look at.
The whip would be a fire whip if I could get the crystal. That is not going to happen, so I was looking at other options. I was considering a 2 talent investment in Initiate of Vahl and Vahl's Flame, but that is a but much for a 6th level character. I was also looking at other whips: Shock whip (can Grab, but what about Pin???) and the mostly sub par Neuronic Whip (can't grab???). Making them do fire damage would likely require a template. Arkanian Manufacture comes to mind, but that is only for ranged weapons.
The rifle is nice to have for ranged combat, but I could probably go with something else.
I do like Weapon Finesse for this character, but I can't fit it I think. Not without dropping WP: Heavy or rebuilding the character. Pin is a must have for the whip I think, NO?
So, sure I want my fire whip. Just not sure how to get it...?
