Notes

I would suggest NOT freezing values in the editor.
Changing inventory and currency values should be done in CAMPS and follow instructions!

Easy Retribution:
When you get a perfect block, likely the enemy will immediately go into retribution.  This makes it easier to get a retribution to engage.

Unlimited Use Items:
When you use items like grenades, potions, or coins the value will not decrease.

More Loot Drops:
May help crates and enemies drop more things.

G:
Press ESC and the value will show.  However, it is not PERMANENT until you SAVE the game then LOAD.  So you should only edit this at a REST.  Edit the value, REST, then EXIT to MAIN MENU, then CONTINUE and the value will be permanent.  The value shown here may NOT BE CORRECT if you are ANYWHERE ELSE than the FIRST SCREEN that pops up that shows your G when you press ESC.

Amount:
Press ESC then BAG, then select a TYPE on the left (like USABLE ITEMS) then click on one of the items to the RIGHT in the list and the value will show.  However, it is not PERMANENT until you SAVE the game then LOAD.  So you should only edit this at a REST.  Edit the value, REST, then EXIT to MAIN MENU, then CONTINUE and the value will be permanent.  Probably best not to edit the amount of IMPORTANT or MISSION items, as those values may be in scripts.  Note that the CURRENCY group in the editor may show same values at times as the values here.
