Knights of Tezoth

Yeah, I'm thinking about one from the list, since the rest is filled with unique skills, sword, and stealth. Also forgot to mention heavy armor.

Writing makes sense, and it fits Alaria for RP reasons.
Leadership is also appropriate for a Knight, and I think it helps represent the tactical side of the character (given the lack of other options).
Bow because Alaria ran around with one for a long time in AA (without it, she would have been simply useless against Valis). And then there's the natural combo: stealth + bow + Path of Air. It will be possible to act as a kind of sniper who leaves no trace. Just like Ivor from Novaru. Though here, of course, I would prefer firearms.
Alaria wore plate armor too, but mostly in RI1. Back then they had serious penalties, and every second named opponent ignored the armor. Plus, cool Remian armor didn't require any such skills and was no worse in terms of stats. And here, on one hand, we have knighthood. After all, what is a knight without armor? And what is a knight without luck? Not the most interesting option, but thematic, not strongly contradicting the character's past, and effective enough, even if boring.

For now, I'm leaning towards giving Alaria writing, as it's the most interesting thing, and specifying throwing knives as backup weapons, wondering how Alaria turned from a classic melee fighter into an assassin.
