[@MelonHead] Thank you, and thanks for taking time to read/help me out.

3 turns sounds good on the stimulant. For the sword... would shortening it help? I hadn't considered the issue of having difficulty drawing it, since I don't think she'll have cause to put it away mid-fight once it's out. She'd use her free hand for her knives and stuff. I feel like she's kinda vulnerable to ranged stuff regardless of what weapon she uses, I figured that would be more of an armor thing. Could you elaborate? Thought about adding something for her to wear over her torso, but I'm not really familiar with what kind of armor would be able to stop or reduce damage from arrows or similar without slowing her down much.

Again though, thank you reading and giving me feedback, I appreciate it :)

Shortening your sword would be the simplest solution, or lightening it. The longsword is predominantly a Knight's weapon, designed to be used with decent armour. I confess I use them quite often with shit armour, but I compensate with a shield and usually above average strength combatants. If you wanted a weapon of significant length that can still be realistically handled quickly, a rapier or smallsword or other renaissance dueling sword is the way forward. If you're going for the medieval feel a simple one handed sword would be fine, or even a short sword. Essentially, you want anything you can use in one hand so you're not stuck facing an opponent with both your hands occupying a sword and no protection from ranged threats. 

You've obviously decided upon a lightweight combatant, so going for heavy armour is not the answer to your problems. Having a one handed weapon that you can use up-close while your free hand can be used to throw out distracting agents like throwing knives and the like should be perfectly suitable. You'll have to use cover effectively and approach sensibly, but you should still be a lot more flexible than if you were carrying a two handed sword.

The sheath thing is completely up to you, but I believe to draw a weapon that long off your back you'd either have to pull it half-way out and then remove it by the blade (cumbersome, if you're taken by surprise you're dead) or remove the sheath and draw it from it separately which is doable, but slow. Running around with a sword out isn't very convenient for acrobatics or anything agile people like to do, so a quick draw system from the hip or lower back is usually preferable. I think ninjas used some sort of back sheath that swung round over their shoulder and allowed them to draw a blade, but they used shorter swords than longswords.

However, in terms of armour there are pretty simple gambesons and the like that can stop some arrows, and certainly things like thrown knives.
