T5 Set Bonuses?

Last I read, there are T5 set bonuses. I’m not referring to the necklace + weapon bonus, I mean just for armor pieces. Supposedly you start getting them after 3 pieces, yet I don’t notice anything new after equipping 3 pieces. No buff, not seeing new procs in combat. Anyone know what exactly the bonuses are, specifically for HoX?

They were removed from the gear. There is now a Rune to buy that gives the bonus

Oh, ok. Thanks.

You need the achievements for killing all T5 bosses, and 90 T5 relics plus some gold.
