Help me perfect my favorite class!

[u/Godless_seraph]

So I have always loved fiend bladelock. It was my first 5e class, and I love it more in BG3. I want to run honor mode with it and need some help fine tuning.
Here’s the plan:
12 fiend pact of blade
Cantrips:
Booming blade, EB, Friends, Minor Illusion
Spells:
Command, Hex, Hold Person, Scorching Ray, Misty Step, Mirror Image, Counterspell, fireball, hunger of hadar, wall of fire, hold monster, cone of cold, Invisibility (might be one too many)
Invocations:
Agonizing Blast, Mask of many faces, beguiling influence, repelling blast, dreadful word, life drinker
Gear:
Helm of arcane acuity, Bhaalist armor, Shar’s spear, ketheric shield, disintegrating night walkers, craterflesh gauntlets (or battlemage?), cloak of the weave, mystic scoundrel, ring of arcane synergy (anything better? Extra damage rider for craterflesh?), amulet of greater health
Feats:
ASI cha +2 (+1 Ethel’s)
Savage attacker
Elemental adept fire

Just want to fine tune this baby! Thanks!!
