Re: Mods and Customizations.
On a tangent, I noticed some time ago that Pathfinder got rid of some of the 'problematic' mechanics associated with the old 3.5 spiked chain by making it short 4 foot weapon, thereby eliminating its reach. I understand the intent, as it does pretty completely eliminate the issues with it. However, I was wondering about a couple of variants that seem viable, but I think this would not open a serious game balance issue.
Chain, Double, Spiked 50 gp
1d6/1d6 2d4/2d4 x2 — 15 lbs.
P disarm, trip CRB
Is a slightly longer chain, which can be used as a double weapon such as quarterstaff. I am inclined to make it the same exotic proficiency of the shorter spiked chain but one could make it be different. One might make it require a 13 STR and 13 DEX perhaps as a prerequisite. (it could also require the short Spiked chain as a prerequisite proficiency as well)
Feat: Exotic Weapon Proficiency (Double Spiked Chain)
Prerequisite: 13 STR, 13 DEX, BAB +1, ?Exotic Weapon Proficiency (Spiked Chain)?
As I said, I might consider one proficient with a Spiked Chain proficient with a Double Spiked Chain as long as they meet all the prerequisites. If people can demonstrate that it is too 'unbalanced' an exotic weapon, I'd consider making the Double be a new weapon proficiency that required the normal spiked chain as a prerequisite.
Feat: Spiked Lunge
Prerequisite: Exotic Weapon Proficiency (Double Spiked Chain), 13 STR, 13 DEX, BAB +3?
As a swift or immediate action, extend the reach of a Double Spiked Chain by 5' for the purpose and resolution of a single attack. This effect only applies to a single attack, and does not apply to any additional attacks earned. It can be used to enable and resolve a single AoO with the extended reach as an immediate action, but as usual counts as their swift action for the next round. This does not extend the reach of any additional attacks earned in the first attack. I.e. It does not extend the reach of any multi-attacks such as cleave or whirlwind attacks, nor the extra attack after a trip, when granted.
Any thoughts on it. I had to admit that I saw some cinematic flavor to the spiked chain concept that was kind of fun, and I think this would be a slightly feat expensive option that would give some flavor to the weapon group, but not make it overpowering.
