Summoner (Pact of the Arch Lich Warlock Subclass)

You have made a pact with a powerful undead archmage; a lich. Your patron whispers hidden knowledge from long dead civilizations, and your patron grants you some of their unholy magic, including the power to control an army of the undead.

Expanded Spell List

The lich lets you choose from an expanded list of spells when you learn a warlock spell. The following are added to the warlock spell list for you.

Spell Level	Spells
1	Ray of Sickness, Inflict Wounds
2	Melf’s Acid Arrow, Invisibility
3	Animate Dead, Summon Undead
4	Mordenkainen’s Faithful Hound , Leomund’s Secret Chest
5	Raise Dead, Cloudkill

Undead Servant

Starting at 1st level, you gain an additional spell slot. This spell slot can only be used to cast Animate Dead. This spell slot starts off at third level and will scale up with the rest of your warlock spell slots. You learn the Animate Dead spell if you don't already have it. This counts against the total number of spells you can know.

Master of Undeath

Starting at 6th level, your Animate Dead spell improves:

When rolling the undead's hit dice, use your charisma modifier instead of their constitution

You can command your undead telepathically 

Lord of the Dead

Starting at 10th level, your Animate Dead spell improves:

Newly raised Undead are raised with maximum Hit Points

In addition you can telepathically speak with any undead you can see within 30ft of you if you share a language that it knew in life and isn't described as mindless.

Undead Healing

Starting at 14th level , your Eldritch Blast cantrip now heals your undead instead of dealing damage to them. All effects of your Eldritch Blast can still occur. i.e. You can still add your charisma modifier to the healing if you have Agonizing Blast, or if you have Repelling Blast, you can push that creature 10ft away from you in a straight line.

Remember these simple Animate Dead tricks.

You can equip your undead with items. So that +1 Sword the Fighter is throwing away? Up for Grabs! ( X o X)¤=[]:::::>

(Unfortunately) Undead cannot cast spells. They are changed to the zombie or skeleton stat block as described in the Monster Manual, which does not include spell casting.

Ask your DM if you can raise improved Zombies or Skeletons, such as an Ogre Zombie. Would be cool if it got +3 t Strength or something similar.

Undead are Immune to Poison Damage.

Undead do not need food, water, air, shelter, or sleep.

Undead can be raised. They make great trap finders. In their own special way. (l|lº □ º) <----- Your Undead, being forced to go into the obviously trapped room.

If you can't choose between Zombies and Skeletons, their Pros and Cons are listed below

Zombies:

Pros. Have more Hit Points than Skeletons, also have a higher Strength modifier. Do not have a weakness to Bludgeoning.

Cons. mindless, useless unless commanded and can’t problem solve, If you say ¨get across that spike pit¨ they will jump in and die. Won’t pick up equipment unless you tell it otherwise.

Skeletons:

Pros. Can do basic problem solving, Has a decent Dexterity score.

Cons. Less Health Points than a zombie, has weakness to bludgeoning, not as high of strength stat as zombie.

So in general, I would use Zombies as tanks or melee damage. I would use Skeletons as ranged damage.
