No decay Assemble Abomination

[Elikur]

Assemble Abomination has skill called "Age of Undeath". You can now only consume minions from the Summon Skeletons and Summon Skeletal Mages, bla bla bla, Abomination does not start to decay until you control 6 or more such minions at the same time.

We have 2 mages by default, +1 from necromacer class bonus, +1 from Necromancer skill tree and another +1 from Skeleton mage skill tree. It's 5.
So, how i can summon 6 skeleton mages? Or i can't? Then what a poin with this "Age of Undeath"?

Age of Undeath means it wont decay until you have summoned 6 skelis. Once the 6th skeli is summoned it starts decaying. The point of the skill is to have the abomination not decay, which works, until you have 6 skelis.

Now it's make sense for me, ty.
