Weapon, armor, and shield conditions

I want to try out weapon conditions for this campaign. Here is how they will work.
There are six categories of weapon and armor condition. There are four categories for shield condition. These conditions apply to both mundane and magical equipment. The conditions, the effects of those conditions, and the time and cost to upgrade to the next condition appear in the charts below. All upgrades require a master amorer (smith or leather worker as appropriate) using a master-crafter work area and tools. Note that mending or similar spells will not change the condition of your weapon, armor, or shield.

For Weapons:

Weapon condition	Modifier	Cost to Upgrade by one level	Typical Time to Upgrade
Pristine	Damage rolled at advantage and double your weapon attack modifier (STR/DEX/etc.) on a crit.	Not upgradable	Not upgradable
Reliable	Damage rolled at advantage	Mundane: 4 times the base price of the weapon. Magical: get quote, expect insanity.	Mundane: twice the number of hours of 1/10th the weapon base price in jinx. Magical: twice the number of days of 1/10th the mundane weapon base price in jinx.
Standard	None, rules as written	Mundane: 2 times the base price of the weapon. Magical: 2000 jinx	Mundane number of hours of 1/10th the weapon base price in jinx. Magical: the number of days of 1/10th the mundane weapon base price in jinx.
Faulty	Weapon damage rolled at disadvantage	Mundane: half of the base price of the weapon. Magical: 500 jinx	Mundane: number of hours of 1/10th the weapon base price in jinx. Magical: number of days of 1/10th the weapon base price in jinx.
Ruined	Weapon damage rolled at disadvantage and subtract 2 (min. damage = 1).	Mundane: the base price of the weapon. Magical: 250 jinx	Mundane: twice the number of hours of 1/10th the weapon base price in jinx. Magical: twice the number of days of 1/10th the weapon base price in jinx.

The condition of armor, shield or weapon can fall in a variety of ways at DM discretion, but the most common way is for you to "sacrifice" the condition by absorbing a critical hit.  When the DM tells you that you were critically hit, and before he tells you the damage, you can negate the critical nature of the hit (it still hits, but not critically) by interceding your weapon, armor, or shield against the brutal hit.  This choice will cause your amor, shield or weapon to decrease in condition by one tier on its chart.
