Exclusive skill for pet Ritualist

I am planning to build a pet Ritualist around the Ghol’s set and wondering about which exclusive skill to pick. At 12/12 Primal Bond offers the character 15% damage absorption and less damage from beasts while giving pets flat bleed damage, 74% all damage and 33% increased crit damage. At 12/12 Master of Death gives the character OA, 75 DA, and 25% vitality resistance while giving pets 50% all damage, 60% acid/poison/vitality damage, phys damage converted to vitality, 12% OA, and 25% vitality resistance.

Using Ghol’s set the build will be focused on poison and acid damage which favors Master of Death. I feel the damage absorption is better from Primal Bond though. It seems to come down to the OA% from Master of Death vs the crit damage and bleed damage on Primal Bond.

Another factor to consider are the other level 50 skills. If you went for Primal Bond you could stop leveling Necromancer at 40 and potentially skip Reap Spirit. I like that skill though, so I might not do that. Even if you didn’t pick Primal Bond I feel Conjure Primal Spirit is too good to pass up.

Which do you think would be better? I will probably go for Mogdrogen, Murmur, Bysmiel’s Bonds, and Shepherd among other devotions as I prefer that route over Dying God, if that makes a difference. Thanks for any input!
