Guild Wars 2

are stackable? i mean, if i infuse all my ascended pieces with +20% gold or magic find, will i end up with 40%-60%-80% bonus?

If magic find stacks multiplicatively like sigils, this is how much MF twelve +20%MF infusions would net you to your base loot chance:

1*+20%MF – 8 of 10 drops won’t be affected = 20% additional chance
2*+20%MF – 64 of 10^2 drops won’t be affected = 36% additional chance
3*+20%MF – 512 of 10^3 drops won’t be affected = 48.8% additional chance
4*+20%MF – 4,096 of 10^4 drops won’t be affected = 59.04% additional chance
5*+20%MF – 32,768 of 10^5 drops won’t be affected = 67.23% additional chance
6*+20%MF – 262,144 of 10^6 drops won’t be affected = 73.78% additional chance
7*+20%MF – 2,097,152 of 10^7 drops won’t be affected = 79.02% additional chance
8*+20%MF – 16,777,216 of 10^8 drops won’t be affected = 83.22% additional chance
9*+20%MF – 134,217,728 of 10^9 drops won’t be affected = 86.57% additional chance
10*+20%MF – 1,073,741,824 of 10^10 drops won’t be affected = 89.26% additional chance
11*+20%MF – 8,589,934,592 of 10^11 drops won’t be affected = 91.41% additional chance
12*+20%MF – 68,719,476,736 of 10^12 drops won’t be affected = 93.12% additional chance

Magic find isn’t a % chance of doing something. It directly increases rare look rates. Multiplicative increases just go 1.2, 1.44, 1.728, etc.
I doesn’t matter though, since it just adds up. You can actually see it as a stat on your hero panel now too, so it’s easy to verify.

The only gear piece where you can put +20% mf is amulet. Only certain amulets have utility slot!

You can? Where? It’s not under attributes.

Ah sorry, I was wrong. Magic find isn’t one of them :/
