Hi,
We are about to start a campaign Vecna: Eve of Ruin and I'd like to play Undead Warlock with melee. No multiclass allowed. Starting at level 10.

We have a group of Fighter (probably Rune Knight), Hexblade Warlock, Bard (not sure about class) and Necromancer Wizard.

I know that Undead Warlock is not optimal, but I like the theme of going against one Lich because my patron (also Lich) said so. And now I am thinking whether to go PAM Undead Warlock with Glaive or if Greataxe with Heavy Armor will be better.

What are your thoughts about this?
