I wanted to have a char that is good with magic and weapons.
After some reading I decided for a hexblade warlock with pact of the blade.
You use charisma for weapons and magic, have some spells and you can curse enemies.
Its not in the PHB, so lets see if this is possible.
Race depends on how stats will be generated, half elf or variant human probably.
I know the level cap is 10, but in order to drive the role playing fans into despair I thought of a level 20 char.
Hexblade12/paladin of devotion8 tunnel fighter.
You stand there, all enemies take damage when they want to walk past you, you add necrotic damage to each attack, with divine weapon you add charisma to hit chance again, you can curse and smite enemies and you use eldritch blast against distant enemies.
I have not played 5E so far so I do not know which char is most powerful. But if nothing else I have have given some people another reason to demand the return of alignment restrictions ;-)
