So I've been messing around gear set ups in mooglebox and I'm mulling over the Serpent's Sergeant's set pieces. Noticing that a couple of them seem to be fairly decent.

The problem is, to get the set effect, which would make them better than decent, I need 3 pieces. And I simply can't find a good set of 3. Which leads me to a dumb question. Does it take 3 pieces with set bonuses or just 3 pieces listed "Serpent Sergent's" to activate the effect? Wanting to know before I start dumping any hard earned seals into this.
