Can a creature that gains several different types of increases to its speed (for example, an enhancement bonus and additional unnamed bonuses) benefit from all such speed increases if the speed increases come from different special abilities but each special ability is named fast movement? That is, is it the abilities' names or is it the abilities' effects—regardless of their names—that determines if the speed increases combine?
For example, consider a character possessing the following special abilities:
- The level 3 scout class feature fast movement (Complete Adventurer 12-13), an extraordinary ability that grants the character a +10 ft. enhancement bonus to his base land speed. The ability's obviated by medium or heavy armor or a medium or heavy load, and it increases at scout level 11.
- The level 2 jaunter class feature fast movement (Expedition to the Demonweb Pits 172), an extraordinary ability that grants the character a +10 ft. bonus (n.b. not an enhancement bonus) to his base land speed. The ability's obviated by heavy armor or a heavy load, and it doesn't increase with jaunter levels.
- The level 1 blade dancer class feature fast movement (Oriental Adventures 38), a supernatural ability that says a blade dancer "moves faster than normal," then has a table that strongly implies that the special ability doubles the creature's base speed. No armor or encumbrance obviates the ability, and it increases at blade dancer levels 4, 7, and 10.
Can the same character benefit from all three?
A Note on the Character: The plan was to have the character also take the feat Fleet of Foot (not from Complete Warrior 99 but from Player's Guide to Faerûn 38—like they couldn't've come up with a different name for these two entirely different feats… yeesh) and end up at level 12 as a fighter 1/ranger 1/scout 4/blade dancer 1/jaunter 2/shadowdancer 2/totemic demonslayer 1 (order's base then prestige classes and alphabetical not periodic) with a land speed somewhere between 100 and 120 ft. (By the way, it'd be great if an answer included how his speed should be determined.) It's a shame if the special ability fast movement from blade dancer overrides the scout's and jaunter's fast movement special abilities, reducing the character's land speed to a mere 80 ft. Also, I know the build's terribly unoptimized, but it's doing what I want at the optimization level I want, trying to use the feat Spring Attack (of all things) to decent effect. You can, I guess, critique the build as part of the answer to the above if you want, but that's not at all necessary.
A Note on the FAQ: The Main FAQ includes a ruling that the special ability AC bonus of the monk, ninja, and swordsage don't stack because a creature can't "benefit from multiple sources that have the same name more then [sic] once" (9). My faith in this ruling is shaken by its context: the ninja's AC bonus already says in its text that it's incompatible with the monk's AC bonus, and the swordsage's AC bonus is incompatible with both because the swordsage's AC bonus only applies when the swordsage is wearing light armor (the others mandating no armor). In other words, the FAQ creates (or restates?) a rule when it needn't do so. This is in addition to broader issues.
