I will post house rules here.

Master crafted weapons reroll rolls of one on attacks

Master crafted armour will half the weight of the armour and increase the max dex modifier by 1 for medium and heavy armour.

Master crafted shields: if you aren't incapacitated, you can add your shield's AC bonus to any Dexterity saving throw you make against a spell or other harmful effect that targets only you.

INSPIRATION
When you have Inspiration, you can expend it to give yourself Advantage on a d20 Test. You must decide to do so before rolling the die.

GAINING INSPIRATION
The main way a character gains Inspiration is by rolling a 1 for a d20 Test, or suffering a critical hit against them.  The DM can also award Inspiration to a character who’s done something that is particularly heroic or amusing.

ONLY ONE AT A TIME
You can never have more than one instance of Inspiration. If something gives you Inspiration
and you already have it, you can give Inspiration to a player character in your group
who lacks it.

LOSING INSPIRATION
If you still have Inspiration when you start a Long Rest, you lose that Inspiration.
