Max of death magic?

I playing a N/M mm and i obviously want to have the higest death magic possible. But i keep seeing the max is ethier 20 or if the higest u can get is 16/17, i dont know which one is right. If it is 20 how do you get it that high?

Blessings from shrines.
Golden Eggs.
Lucky chances on your +1 (20%) items (if you have them).

Well teh max attribute points are +12,
The Max Rune is +3
The Max inherit boost (helms) is +1
The Max from Golden Eggs is + 1
The Max from shrine Blessings is +1
The Max from a lucky 20% chance mod is +1 (i beleive, unless u can get +1 on wands)

so that adds up to 19

on a side note due to Awaken the Blood Blood and Curse can go up another 2 to 21 max just as Eles can go up to 23 with the Glpyh and Elemental Lord spell.

Isn't the max for an attribute always 20? And yes the highest level of death magic is 19 so that would make a lvl 29 Flesh Golem if i'm correct^^.

We can only go upto +19 as PC's. the lvl 20 is put in there because Monsters can get to a higher lvl then we can Upto I belive lvl 30. They are the ones that can get the 20 in an attribute. So the skill description has to takeinto account their abilities also so you know what u could be facing.

I don't know why there's a cap, but there is supposed to be a max player cap of 20 on attribute levels. The +1 attribute 20% of the time is not counted for that, so you can get to 21 occasionally.

I think Necros can only get to 20 in Blood and Curses using Awaken the Blood.

16 from max attrib. + hat + sup rune
1 golden egg
1 from blessing from avatar
1 from lunar blessing
2 from Awaken the blood (for Blood/Curses)

So max Death is 19 and Blood/Curses is 20 (cap) and if you have a +1 weapon, you should be able to hit 20/21 respectively 20% of the time.
