No bro, he doesn't. He has 11 base atk and 10 base AS. He fails to double Mercs/Myrms unless he gets like 2-3 spd procs. Brigands have anywhere between 20-22 hp and 0-1 res, so he'll only ORKO like half of that. He'll usually get archers and soldiers, though. Cavaliers he might need a level up.
But regardless of all that, this isn't worth of a high number relative to other units, since it really isn't hard to beat this levle of offense.
But how do you train a guy like this efficiently when Kent/Sain will absorb 90% of the kills on their way to the throne while Lucius is getting 2HKOed? And even if you do, what difference does it make for him? In Ch18 (the first chapter he reasonably gets any action), I don't see Lucius any higher than 8/0.
8/0 Lucius: 20.8 hp, 10 mag, 12 spd, 1.5 def, 9 res, 3 luk
Lightning: 14 atk, 12 AS, 27 avo
Steel Sword: Mercs: 28 hp, 17 atk, 2 res, 12 AS
Lucius 3RKOs
Merc 2RKOs (with 3% crt)
Steel Bow Archers: 24 hp, 16 atk, 2 res, lol AS
Lucius (barely) ORKOs
Archer 2RKOs
Nosferatu Shaman: 21 hp, 17 atk, 8 res, lol AS
Lucius does 2x7, so a 3HKO (2RKO) not even taking into account healing
Shaman (barely) 3HKOs
Steel Lance Peg: 21 hp, 17 atk, 6 res, lol AS
Lucius 2RKOs
Peg 2RKOs (with 1% crt)
Take HHM Sain now for example. Without even looking at the stats, I can tell you right now he ORKOs every single one of these enemies other than the Merc which he 2HKOs. He'll likely get 2HKO'd by the Shaman unless he uses a Pure Water, but with somthing like 25 hp/7 def he can take an extra hit from all of these, and with 26 hp/8 def (more likely...this is 10/0 Sain) he'll take two extra on some of these occasions.
And yes, you have Sain lower than Lucius on HHM.
Raven support takes forever on an efficient playthrough, and restricting Raven to Lucius' whereabouts isn't beneficial to begin with. Raven is the kind of guy you sometimes want to ferry to the other side of the map to saw into enemy faces. As for Goddess Icons, you do get two of those, but I'd rather sell them, never mind the fact there's some other 1% crit chances I might want to eliminate as well. Crit chances suck because it's instant end of the game if they do trigger.
