Beatstickery:
Let's be honest, any solo character wants to avoid getting into fights as much as possible. You will almost always be outnumbered and action economy is not your friend. That said if you get caught in a combat scenario and cannot talk or flee you aren't a pushover. Your standard attack would be Green Flame Blade in conjunction with a sword or shillelagh'd stick, getting +Cha Fire damage on top of the weapon and cantrip damage due to Radiant Soul as well as potentially +1d6 from Hex and/or Sneak attack if using something like Darkness for advantage. That's if you're caught in melee though, you'd much prefer to cunning action to get some distance and pepper the opposition at range with EB
Tidbits of note:
- Elven trance means you don't have to worry about watches while resting
- Dex based AC means you don't need to make yourself vulnerable to rest or socialise
- Rituals help counteract Str and Int tasks that you might otherwise suffer performing (carrying and learning/knowing things)
