Typically I've played characters that are very flamboyant and confident/full-of-themselves. Very extroverted.
Recently I tried playing a fighter who had low intelligence and charisma, but actually it wasn't very fun. I feel like couldn't fully participate in decision-making or conversation if I honestly rped him as envisioned. He was a combat monster, but very one-dimensional. He could only swing a sword or shoot an arrow. He was really good at that, but that's all he can do. It made me realize I love characters with lots of options. Well-rounder is much superior than min/max in my opinion... plus it's no fun to play with other people either. Go underdogs!
Autumn has an abysmal CHA, and her human-adopted-by-elves background will reflect that. In one of the last adventures here there was a ranger who had no self-confidence but was actually really talented otherwise. I am 'borrowing' much of that theme. As she adventures more and more, I think she will come to realize how powerful she actually is. That's how I envision her overall 'plot arc'. Plus, I never really played a hard caster before, so that will be new and intriguing. Especially a druid, where I can roleplay how she deals with how the nature magic gradually increases in power. Some issues will be how she copes and comes to terms with how it manifests itself, and maybe how she ultimately harnesses that power.
Plus she will be a druid that casts fireballs. Maybe she starts a forest fire. Lot's of inner character turmoil there! Maybe I will handle it like spiderman.... "with great power comes great responsibility." Well, Ben Parker.....
