D&D 5E Help With Picking a Pact Boon

[TrueBagelMan]

So I’m having trouble choosing a Pact Boon for my Sorlock. I’m having trouble choosing my Pact Boon because each come with there unique perks.
Pact of The Blade
With Improved Pact Weapon I can cast spells using my conjured weapon and have no use for +1 melee weapons.
Pact of The Tome
With EI: Book of Ancient Secrets I gain access to spells such as Find Familiar and Floating Disc. I also gain three cantrips that don’t benefit me much.
Pact of The Chain
This pact basically gives you a better version of Mage Hand since the familiar can be invisible and can carry about 20 pounds. Also can be an amazing messenger and scouter.

My character is going to a mix of Divine Soul Sorcerer 17/ Hexblade Warlock 3
With the Feats Elven Accuracy, Warcaster, and Sentinel.

Tomelock can get access to all ritual spells. Bladelocks can have their own +1/+2/+3 weapons but those may require UA invocations.

Infact there are two UA invocation that can enhance your Chain Familiar.

But....depends on what's allowed.

 

[TrueBagelMan]

What UA invocations?

 

[Weiley31]

Class Variant UA has the chain pact upgrades two of em

+3 pact weapon invocation is in Wizards and Warlock UA.

 

[TrueBagelMan]

Pact of The Blade has improved, superior, and Ultimate pact weapon. Also you can attack twice with your weapon and Life Drinker. As a Sorlock I don’t gain access to any except improved pact weapon.

 

[TrueBagelMan]

All being in PHB and xanathars guide to everything.

 

[TrueBagelMan]

Pact of the chain has Gift of The Everliving Ones and Voice of The Chainmaster.

Then The Pact of The Tome gets Book of Ancient Secrets. The one that makes it where you don’t have to sleep has no use for me.
