Two-Weapon Fighting

[Spatula]

Improved Multi-Weapon Fighting, Greater Multi-Weapon Fighting, and Perfect Multi-Weapon Fighting are all in published WotC products. (D&Dg, ELH, MotW, I belive.)

I don't have Dieties & Demigods or the ELH so I can't speak for those, but none of those feats are in MOTW. MOTW has Greater Two-Weapon Fighting (*not* Greater Multi-Weapon Fighting), and that's it.

I just checked, the're in the ELH. (As non-epic feats.)

Out of curiosity, what are the prerequisites? +9 BAB for Improved and +15 for greater (like the non-multi versions) or something else?

OK, apparently Delverbash uses a different formula to calculate the cost of stacked powers. In this case, though, you really should be using the boots of striding and springing cost from the DMG erratta. They're now a base of 5 or 6kgp.

He uses his own system to balance out his specific contest.

DMG calls them 6k
2k for Expeditious Retreat
4k for Jump +10( 10^2 * 20 *2 for secondary)
You could even say they're underpowered at that cost, because the Jump spell gives a +30 bonus for the same cost.

In any event, unlimited access to DMG power stacking rules or no, I would not expect Striding and Springing powers to be ubiquitous in a party of 12th to 14th level adventurers. There are too many other useful things for such characters to spend their money on. (And in neither the 9th level, the 12th level, nor the 14th level campaign I played in did more than one character have such boots--and often not even that many. Other peoples' experience obviously may differ).

Every campaign I've been in, they are Very High on all players wish lists.

Boots of Springing and Striding are wayy freaking overpowered, at 2k, at 6k, and even at 10k. I charge 20k in my campaign, but its mostly because I dont want people to have them. Double your speed is a little too sick imo. Rationally, I guess they are OK at about 10k, but they irk me. Ive played in too many games where they arent even eratted to 6k, so the whole party gets them for 2k. Bleh.

My final version:

Note: As usual, the normal entries over-ride the core rules, for my purposes.

Ambidexterity [Fighter]
You are skilled at using your off-hand(s).
Prerequisites: Dex 15+
Benefit: You suffer no penalty on attack rolls with your off-hand(s).
Normal: You suffer a -6 penalty on attack rolls with your off-hand(s).

Multi-weapon Fighting [Fighter]
You wield multiple weapons effectively.
Prerequisites: Dex 13+, base attack bonus +4
Benefit: You can make an additional attack with an off-hand weapon, at your full attack bonus. With a +9 BAB and Dex 15+, you can make a second additional attack with your off-hand weapon at a -5 penalty. With a +14 BAB and Dex 17+, you can make a third additional attack with your off-hand weapon at a -10 penalty. With a +19 BAB and Dex 19+, you can make a fourth additional attack with your off-hand weapon at a -15 penalty. You take a -4 penalty on attack rolls when using this feat, or a -2 penalty if all off-hand weapons used are light.
Normal: You cannot use off-hand weapons to make additional attacks.
Special: If you are wielding more than two weapons, the number of additional off-hand attacks you can make increases. With every additional off-hand weapon, you can make a number of additional attacks equal to the number of attacks you can make with your first off-hand weapon, at the same attack bonuses. For example, a 20th level fighter with three weapons could make 12 attacks.
Epic Attack Bonus is not counted as BAB for the purposes of gaining additional off-hand attacks with this feat.

...{snip}.....
Normal: You cannot use off-hand weapons to make additional attacks.
...{snip}.....
Epic Attack Bonus is not counted as BAB for the purposes of gaining additional off-hand attacks with this feat.

It's already in the ELHB that Epic bonuses don't increase attacks per round...I'm not sure that's necessary to include in the feat, unless you have forgetful players.....

Could you explain your "normal" part above? You don't allow someone with two weapons to strike with the second weapon without this feat? Isn't that at-odds with your Multidexterity feat?

 

[Kraedin]

The quasi-errata for the ELH indicates that EAB counts as BAB for all purposes with feats, so I added that line so people wouldn't end up with 3 main-hand attacks and 4 off-hand attacks.

You could make an attack with an off-hand weapon, but it would have to be part of a normal attack sequence. Like a 20th level fighter attacking twice with his longsword and twice with his shortsword.
