Does a sundering string stack on hornbows?

my moderator friend said it doesnt and has been discussed alot, but i didnt find any threads except this one http://www.guildwarsguru.com/forum/s...+stack+hornbow which isnt helpful.

if they dont stack, that seems pretty unfair to the hornbow. :-P anyone got evidence for either way?

They stack. Who's your "moderator friend"?

Indeed, they stack. I can confirm it from recent testing on the Isle of the Nameless. Nevertheless, remember that a 20/20 string, for example, only gives you 20% additional armor penetration every 5th shot.

Now, Pentrating SHOT and the Hornbow Armor Pen do not stack. Are you sure that's not what he was talking about?

ty for the link Sav.... naw, it was about a sundering string on a hornbow.
