Level max is 5. For ex. Stick at LVL= 1 ATK. Stick at lvl 5 = 5ATK. For every level up, a x1 multiplier is added.

For stronger weapon's like Burnt pan, Gun, ect. Since their attack is high by default and therefore the attack going from 25 > 50. That isnt fair, so for Higher Damage weapon, Reduce the damage multiplier by half. the least multiplier you can get is 0.025.

Your weapon level up's For every monster you kill.

( Doesnt apply for PVP. )

Lvl 2 need's: 10 Kill's.

Lvl 3 Need's: 30 Kill's

Lvl 4 Need's: 70 Kill's

Lvl 5 Need's: 110 KILLS!

And I have another Idea: Weapon SKILLS.

SKILL'S change how the fight's happen.

Skill's can give buff's. Or Enemy debuff's.

Ill give 5 you could use.

1: Sharpness: Damage x0.25

2:Shiny...! : Gold drop x0.5

3: Enchanted: XP Drop x0.25

4: Bigger they are: +1 Rectile to add more damage.

5: Nimble: Defense x0.25.
