There are three main types of Brigands in the prologue:
Common ones: 36 hp, 5 def, 0 res.
Azel: ORKO
Alec: 2RKO
Noish: 3RKO
Lex: 2RKO
These are the most common. Azel can 1 round them, but there are only 2 or so near his range.
Alec deals 20 damage to them, noish 16. However, Noish is the only one of the two that has a chance to ORKO (7%lol) It doesn't really matter that Alec can 2RKO, because someone else will finish the brigand anyway.
Hand-Axe
These are the strongest. Not only do they have handax, but they have more hp.
45 Hp, 5 def, 0 res.
No one can ORKO them.
Alec 3RKO's them
Noish 3RKo's them
Azel 2RKO's them, but they kill him on second shot.
The third is the first with more hp.
