Haste Spell ?

[Amiculum_Nocturnus]

The Haste Spell increases Attack speed by 15%.

Does this stack with Enhancement Hastes (ie. Fighter Haste Boost I - 15% Haste)?

If Yes, are they an additive stack, 15%+15%= 30% haste during that time or a exponential stack, 15% applied then 15% applied?

[Visty]

they stack, yes

and i think eladron once said they stack multiplicative for a total of 32%

My math is rusty, please help. How would we get a 32% haste from two 15% haste boosts?

1.15 * 1.15 = 1.322

It's not as simple as 15 +15 = 30

You apply the first +15% to your normal attack speed. Then you apply the second +15% to your already increased attack speed. Thus, according to the previous poster, gets you around +32% total attack speed.

100 + 30% = 130
100 + 15% = 115 + 15% = 132

32/100 = .32 or 32%
