[3.5] Stacking Haste

[Vegan Zombie]

Hey guys, just wondering if anyone can tell me:

Does haste stack with Rapid Shot? Also, with Flurry of Blows? AKA one extra attack on a full attack, in addition to the extra attack granted by these abilities.

Thanks guys!

As far as I am aware, yes.

Haste stacks with everything that doesn't say "this doesn't stack with haste".

Level five monk throws shuriken. She can throw one normally. Flurry gets that to two. If she has TWF he can throw an extra with her off hand (three). If she has PBS and rapid shot he can throw another one (four). If haste has been cast on her she gets one more attack at her full attack bonus (five).

This comes at a great penalty. The attack bonus will be 3 BAB + 1 Haste - 2 Flurry - 2 TWF - 2 Rapid Shot + Dex or Dex minus 2.

Generally speaking, any "extra attack" ability that doesn't stack with Haste says so specifically:

When making a full attack action, the wielder of a speed weapon may make one extra attack with it. The attack uses the wielder’s full base attack bonus, plus any modifiers appropriate to the situation. (This benefit is not cumulative with similar effects, such as a haste spell.)

Pff, Monk. A Whirling Frenzy Barbarian gets the same extra attack, plus another attack next level, for a total of six attacks at level 6!
