Which of the following movement speed enhancements are stackable (if any):
- Monk speed
- Barbarian speed
- Dash feat
- Those boots of speed
- Haste (spell, potion, or sword)

I think that's all the speed-ups in the game. Just want to make sure I don't waste any that aren't stackable.

Doesn't the panther get a bonus to speed?
Anyway I don't know what stacks but you could test it by making 2 chars and giving them the same abilities to start and add one ability at a time to one. Then use the single file tight formation and have them run across a map and see if there is a difference. If it works I'd guess a Druid15/monk15 with dash,boots of speed, and golden heart would make a great scout/item collector. since stunning blow is a special ability can you use it shifted?

They stack, thankfully. It's what I use on my Mage, cast improved haste and wearin' those you practically fly! lol JK JK. But yeah unlike BG2 speed buffs do stack

You can't make a Barbarian/Monk (alignement Chaotic/Lawful)...

My monk is using monk speed + dash + haste to brutal effect. She's my scout and things are going very nicely so far. She's only level 6, and I can't wait to see what she does at higher levels.
