Restart your computer if neither Nexon or Steam is not working because there probably a leftover program preventing Maple Story from starting. (You may need to do a full shutdown to fully clear the memory by holding down shift when selecting the power off button in the start menu, https://www.howtogeek.com/349114/shutting-down-doesnt-fully-shut-down-windows-10-but-restarting-it-does/)

Probably cause you are one of the very few people to suggest it but did not get any traction.

When you go 1-hand, you'll never feel the regret of "If only I was a bit faster" when you are bossing.

The 5% damage boost in the long run has little impact due to the damage formula [... * (%damage + %damage vs bosses) * ...], when you will get 30/40% damage vs bosses on a lot of stuff (the 5% damage boost is just to entice people to use axe because everybody think axe animation is ugly).

Potential road map if you're not going to buy pre-scrolled/cubed equipment.
(May be more expensive than buying an equipment, but you get the satisfaction of making your own gear)

0.5.) Using occult cubes
-Get weapon, secondary, emblem to +3% attack
-everything else to +3% dex
-average cost for each equipment: 30 occult cube and 2 potential scroll

1.) Using occult cubes (with a lot of epic potential scroll to save hours of getting to epic with occult 1% tier up rate)
-Get weapon, secondary, emblem to +6% attack
-everything else to +6% dex
-average cost for each equipment: (2 epic potential scroll and 30 occult cube), (200 occult cube)
(note that the re-rolling cost can get pretty expensive when using that many occult cubes on lv 140+ equipment)

2.) Using occult cubes to get double lines at epic tier or getting to unique tier using master cube (drop from mysterious/legendary veins, bosses, crafting)
-Get weapon, secondary, emblem to +9% attack or +30% boss damage if it is at unique tier (emblem cannot get %boss)
-optional, get +30% ignore enemy defense on weapon, secondary, emblem for bosses with 300% defense (chaos vellum, Lotus, Damian, etc)
-optional, get decent sharp eye on glove if you don't have enough space (or buff freezer) on your 5th job matrix for it
-everything else to +9% dex
-average cost for each equipment: (200 occult cube), (80 master cube)

3.) Using meister cubes to get to legendary tier (main source come from crafting)
-Get weapon, secondary, emblem to +12% attack or +40% boss damage if it is at unique tier (emblem cannot get %boss)
-optional, get +30% ignore enemy defense on weapon, secondary, emblem for bosses with 300% defense (chaos vellum, Lotus, Damian, etc)
-optional, get decent sharp eye on glove if you don't have enough space (or buff freezer) on your 5th job matrix for it
-optional, get decent speed infusion on glove if you don't have enough space (or buff freezer) on your 5th job matrix for it
-everything else to +12% dex
-average cost for each equipment: (120 meister cubes)

Consider getting a Fafnir weapon to get that +30% boss damage set effect.
Consider putting any trash soul on the weapon if you need +20 att when training (not as suseful on bosses as dying reset it back to 0).
