Does weight advantage Medium Cluster Jewel Notable stack?

The notable reads
+20 to Strength
Mace, Sceptre or Staff Attacks deal 30% increased Damage with Hits and Ailments
4% chance to deal Double Damage while wielding a Mace, Sceptre or Staff

Can the double damage portion of this node stack by having multiple of these jewels?

It does stack.

As the infamous Herald-stacker builds taught us, Cluster notables will stack if multiple copies of them are allocated. This is a different behavior from ordinary Notables and Keystones.

So yes, allocating 2 copies of that notable will yield a total of +40 STR, +60% incDamage with maces, scepters and staves, and a 8% chance to deal double damage with ANY skill (even spells) as long as you wield a mace, sceptre or staff

Small correction, it would be 2 seperate 4% chances to deal douple damage.

Atleaasst thats how i have understood the "stacking" of various % chance effects to work.

No Maxtrux was right. 8% chance to double damage if you stack 2.

And you can stack anything and everything cluster jewels give. Except the keystones like Hollow Palm or Secrets of Suffering.

Well i guess there is the elemental exposure debuff notables that wouldn't stack.
