Tanky Seeker Tomelock Warlock

[Talionis]

I think we are looking at a Seeker Tomelock. Looking for a dip to make it more survivable and Tanky, in the sense of taking a beating not holding aggro.

You have a few options.

You can get Life Cleric for things like bless, shield of faith and healing spells and when you finally get Vampiric Touch you are healing way more with it and will be sitting on 20 AC with full plate and a shield.

You could go Fighter 1 to get constitution saves for concentration saves and 21 AC with defensive fighting style. <- This is probably your best bet

Can't really run Barbarian because you are a tomelock and not a pact of the blade; if you rage you can't cast spells.

If you run paladin you have to get 2 levels for spells and AC boost but you'll have access to smiting.
