With winter break arriving Im going to be doing alot more time to D&D, and im looking for a new class idea or setup and since it has been months since i have played I figured maybe the community can help me out.

Ive always loved the different elements of this game and I know certain skills allow you to change the element on your weapons, Is there a class/multiclass outhere that will let me change the element of my weapon, self heal (Spell buffs are a +), and possibly do traps?

Prefer to do multiple weapons as well not just sticking to 1 maybe 2 weapons so I can get some variety like maybe all the Great Weapons, or Different Swords and Sickles with Mauls etc.

Maybe a Rogue Ranger? AA lets me change the Ammo I fire and I get two weapon fighting with whatever I want?
Or warlock with a greataxe while the bursts do there thing?
A Arti with a Bastard sword?
Eldritch Knight WF?
Or any combination of them?

Thank you for all the help!
I am fairly new with the game...
