Warlock Pure Summoner - 5th Skill to Max: Summon Defiler? Summon Goatman? Blood Oath? Other?

Hi

I'm at L78, playing Warlock "Pure Summoner"
----
I mainly only use buffs/debuffs (

Sigil Lethargy,

Death Mark and

Engorge), while my Act 2 Merc and Minions (

Summon Goatman,

Summon Defiler and

Bind Demon) do all the killing.
----
I like the playstyle, and I have no serious offensive or defensive issues
(I haven't died yet and only get closer to die once - mostly because of slow down... - and can clear areas and kill bosses satisfactorily )

That said, I've already maxed:
-

Bind Demon
-

Demonic Mastery
-

Death Mark
-

Sigil Lethargy

And I'm thinking about the next skill to max.

I want to maintain my current playstyle/build, so I don't want to invest in a direct attack spell (

Blood Boil,

Echoing Strike,

Apocalypse, etc...), not to mention they wouldn't be very effective without the points in their synergies...

I don't think it's worth spending points on:

-

Engorge
Current L22 (35 ias) is already the max ias possible

So I think my options are:

-

Summon Defiler
Shared damage is 54% (L23) and it increases up to 58% (L38) which represents a 7.4% increase in all my AoE damage

-

Summon Goatman
When maxed I will have a 35.5% increase in damage
-- Current damage (L23)

Damage: 2585–3008
Attack Rate: 28 frames (0.89 hits per second)
Damage per Second: 2491

-- Maxed damage (L42)

Damage: 3537–4045
Attack Rate: 28 frames (0.89 hits per second)
Damage per Second: 3376

-

Blood Oath
Since people are saying that the tooltip is wrong and only hard points affect the redirect % bonus, I can go from 5% redirect to 43% redirect !!!

- Another skill?
(At some point I thought about

Hex Bane/

Hex Purge/

Hex Siphon. but they don't help my Minions damage ...)

OBS: numbers from https://maxroll.gg/d2/d2planner

Personally would go for

Blood Oath max (or as high as possible).
It boosts your demons and buffs yourself aswell in the process.

Consume?

@ lvl 20 lasts 440 sec, and (apparently) you gain the attributes of the consumed demon.

can the defiler or

Goatman spawn with an aura?

1 - As a "Pure Summoner" I don't attack
so I keep the 3 demons alive.
as

Consume bonus only apply to myself not to my minions...
(ex:

Consume my Summon

Goatman will not increase my other minions' physical damage and

Consume my

Summon Tainted or

Summon Defiler will not increase my other minions' fire/magic damage)

2 -

Summon Defiler or Summon

Goatman cannot spawn with auras (and neither have any random properties/abilities, they always spawn with the same properties/abilities)
