Simple question here.

Do Talismans such as Penetrating Talisman stack? So for Penetrating the bonus for having a set of 2 is a “45% chance to gain magic penetration on perfect basic attack attacks”. Does equipping 2 sets increase the chance to 90% or does it not?
I’m trying to equip some older talismans to free up space in my inventory and I wanted to try this out if it stacks. If not I may just sell them. Thanks in advance!
