Weapon Bonus, goes it stack ?

Hi guys.

I noticed in Vasburg Armory, that you can buy for example:

a Fire wand, with the following bonuses:

Halves casting time of fire magic spells (20%)
Halves skill recharge of fire magic spells (20%)

and a Flame Artifact with the exact same bonuses.

my question is then, does those bonuses stack, so it becomes 40% insted of 20% ?

Won't stack like that, but the two 20% faster recharges (for example) do work together as separate checks. Essentially it has a 20% chance of faster recharge and then another 20% chance after that, which would have a small possibility of the already halved recharge getting halved second time for even faster recharge.
Like rolling a die twice instead of just one time.

okey so eighter way, it's better to have 20/20 than just a single 20% ^^

Well thanks for that guys, helped me alot. ^^

And here's Savio's picture on the subject:

As long as one person understands it, I don't mind ^^

Now, as far as the incorrect posts go, I'm sick of seeing it so I deleted them. There's no good reason to leave wrong posts around to mislead more people.

i see so you deleted my post which was correct, and not misleading. well thanks a bunch.

Your post assumed that when both chances occured it was still only half cast/recharge, which is incorrect. When both mods trigger, the half recharge is halved again, meaning it only takes a quarter of the time to recharge. You don't get a 36% chance of halved spell recharge with 2 20% mods, you get 32% chance of half recharge, 4% of quarter.

The correct percentages are:

but okey.. no matter how you turn and flip it inside out, theres still better chances for faster recharge and cast with 2x20%.

thats all i wanted to know. ^ ^
