Joining a friends table for a short guest appearance Need Ideas for a level character 2014 edition

Next week I'm joining my friends table for a couple sessions

The group is at level 9.

They consist of a Druid, Bard, Barbarian, Artificer and Warlock.

I can play what ever I want. I can even Multiclass. Just have to use the 2014 rules.

Help build a character with your ideas.

Thanks!
