Hmm. Why even bother with crossbows and bows if daggers deal so much damage?
This is "just" a guy with a sword who attacks his opponent head-on.
-- Let me describe to you in detail how I see it. Approaching him in melee combat is equivalent to death. Attacking him in melee combat and receiving a counterattack is also equivalent to death. If the esteemed Miss Kalina then gathers us back together piece by piece, -- a nod towards the doctor. -- then it won't be pleasant for everyone to continue living like this, and I don't want anyone here to suffer so many irreversible injuries.
-- Due to our foolish history and the strange property of the artifact blade of our opponent, he has an additional advantage over us. We will have to expend twice as much effort if we want to paralyze or stun him. We cannot slow him down or immobilize him. His daggers can even decapitate us from a distance. Literally. Our advantage in range is not significant, given his speed. If we can ambush him somewhere on higher ground or on buildings, that would be ideal, but we shouldn't rely too much on that.
He throws a vial of poison to Garrett.
-- Our advantages: numbers, will, and luck. Thank you for agreeing to help us here, Miss Aiyano, I don't know how to thank you... In the end, our weapon will be the poison on Mr. Garrett's crossbow bolts, your ability to completely incapacitate the criminal, and Miss Keliandra... Your task is, please, learn "Earthquake," you mentioned before that you have the potential for it. I will study "Fireball." This is all assuming that the criminal is already inside the walls. Miss Aiyano, may I borrow your compass for a moment to confirm this one way or another?
-- I really have a feeling that this still might not be enough. Miss Aiyano, if you are not retracting your words, what other talents do you possess?
