Level 30 Flesh Golum possible?

I have a minion master with a death+1 set...

There is a blessing called: necromancer of Grenth
For 20 minutes, all your necromancer attributes are raised by 1

I tested a bit with this combination (just for fun). My bone horrors and fiends can reach level 20 using this. But i never saw a flesh golum with level 30 (or just higher than level 28), and i think i have tested it a lot...

Is it even possible? Or would it be capped at level 28?

It is possible to get a lvl 29 since with +1 (20%) you can get a lvl 28 and with blessing it goes up to 29 but no lvl 30 is impossible.

28's the highest for me too!

Well in theory you might be able to get level 30 minions with a wand +1 (20%) and and off hand +1 (20%) and the blessing - but if it can be done it would only happen 4% of the time.

Well there is no wand with +1 Death so you can't have lvl 30 minions...

And here's a pic of my lvl 29 Golem

Well, the reason why i said "level 30" is because a death+1 focus or staff can give a level 28 flesh golum, while level 26 is "normal". That is a difference of 2...
