Yeah only one of the eldritch blasts will be 2d10, so 3d10+10 for most locks at level 8ish. But you can add in hex or similar effect as form of dread does not require concentration. So 3d10+2d6+10. Not massively above baseline but solidly enough. In context heavy weapon master is one of the big guns of DPR it grants +10 dmg at a -5 to hit +1d10+1d6 is about 8dmg and at no - to hit. And you don't have to choose first which eldritch blast is necrotic so you can make sure its on the one that hits, if both are hitting on the one that crits if one crits. And its level 10&14 powers aren't bad either.
And as a point with frightened given that you can add in a push effect to your eldritch blasts, you get dudes shoved out of melee who can't approach you. And if you are behind a line of friendlies that means it can't approach your friends either. Undead is fantastic. Fathomless with its tentacle also offers some interesting control. Genie gets a small damage boost on one eldritch blast, but its other features are pretty solid. If you go Dao, or maybe not as you have a druid but dao with crusher feat can and push/pull effects on their eldritch blast can get pretty nasty with spike growth spells.
I'd say stick warlock. A moon druid should be enough on the front lines on their own for a party of 4 and you have a forge cleric to back them up you don't need a 3rd there, but you already have the valor bard if you need a 3rd. So 3 people comfortable on the front lines out of a party of 4. You don't need to step in there. What your party probably needs is DPR as none of those are great there stick warlock and support from the back with spells/eldritch blast. If the DM is letting you change a bunch of things, maybe the pact and some invocations. Fathomless, Genie, and the undead can add some extra DPR on their basic attacks fairly well, hexblade as well. Or at least the invocations, old one is fun even if it isn't the best mechanically.
I have to agree here... Undead Warlock is a beast! At your level, you'd already have the class features below:
Form of Dread
1st-level Undead feature
You manifest an aspect of your patron’s dreadful power. As a bonus action, you transform for 1 minute. You gain the following benefits while transformed:
You gain temporary hit points equal to 1d10 + your warlock level.
Once during each of your turns, when you hit a creature with an attack roll, you can force it to make a Wisdom saving throw, and if the saving throw fails, the target is frightened of you until the end of your next turn.
You can transform a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
The appearance of your Form of Dread reflects some aspect of your patron. For example, your form could be a shroud of shadows forming the crown and robes of your lich patron, or your body might glow with glyphs from ancient funerary rites and be surrounded by desert winds, suggesting your mummy patron.
Grave Touched
6th-level Undead feature
Your patron’s powers have a profound effect on your body and magic. You don’t need to eat, drink, or breathe.
In addition, once during each of your turns, when you hit a creature with an attack roll and roll damage against the creature, you can replace the damage type with necrotic damage. While you are using your Form of Dread, you can roll one additional damage die when determining the necrotic damage the target takes.
Which means that when you're in Form of Dread, your Eldritch Blasts are doing 2d10 + (depending on Invocations) of Necrotic Damage x2 Blasts. That's 4d10 + as a Cantrip... plus Fear as a Control mechanism. And you're only a few levels away from 3 blasts per round. That's crazy single target damage, and amazing crowd control against minions...
It also works great with Hexblade, if you want to get into melee again... although based on your party, I'd probably stay in the back.
My ONLY issue with playing a blaster is that it can get a bit repetitive, but the RP and out of combat support it brings to the table makes it all worth while.
Couple of mistakes here my friend. Firstly, Grave Touched lets you add additional damage to ONE attack so only ONE Eldritch Blast beam will get boosted because each beam counts as a separate attack.
Second point concerns the "It also works great with Hexblade" part. Undead and Hexblade are two DIFFERENT subclasses so you cannot combine their features.
Nitpick over have a nice day.
Correct on both fronts - good catch on the Grave Touched (I had missed that), and I meant Pact of the Blade, not Hexblade.
And as a point with frightened given that you can add in a push effect to your eldritch blasts, you get dudes shoved out of melee who can't approach you. And if you are behind a line of friendlies that means it can't approach your friends either. Undead is fantastic.

You all may have just sold me on Undead Warlock, that sounds bad ass.
This.
My Lizardfolk Barbarian / Undead Warlock certainly thinks so...
Lol nice
