Hi,
I checked rapidly and did not see this issue raised yet.
Just to warn all the users of this necklace to basically never switch it out for some other necklace, as this will cause you to lose action boosts (I know, up to now this sounds like it is what should happen, but read on)
I reported the bug as such:
1)equip Verik Necklace and shrine. Note the number of action boosts.
2)unequip Verik Necklace, this does lower all the action boosts by 2.
3)re-equip Verik Necklace. Nothing happens, as it should.
4)unequip Verik Necklace again, this does again lower all the action boosts by 2. This is wrong. You can repeat this and eventually bring your number of actions boosts to zero.
