Weaponry: Aeterna is quite skilled with a sword. She's taken up gladiator training years ago, but unlike most gladiators, she discarded the shield and took the time to learn how to dual wield properly. Unless in a fight where she has to show this, she will not show that she knows this, preferring to keep it hidden and use it as a secret weapon against someone rather than go all in at once. She keeps a larger sheathe on her, that looks intended for one large sword, and keeps two swords in it for emergencies.
Speed: Due to being a petite person, she is very fast. She can make strikes before people realize it if they let their guard down for even a moment. She can keep someone on their toes and wear them out if given the upper edge quite easily, and is a hard to take on opponent due to this. From extensive training, she can also dodge quite easily, though someone who is skilled can manage to pin her and catch her off guard if they time attacks right.
Intellect: Craziness aside, she's a smart person. She learns to adapt to situations and try to make them to her favor, even if it might seem impossible at the time. She often will manage to turn something around, even if it might look like she's going to lose. Due to her attentiveness, every place she might end up fighting in, more often than not, is used to her advantage because she finds something she can use. She isn't dumb enough to charge an opponent, unless severely provoked by something that might make her panic.
