Sharing it here in case any one else need this feature in their game.
Features:
[1] A chance of double exp/gold based on a sum up total of actor's luck/dex that stacks with the game default double gold/exp.
[2] The more actors with the tags in the battle the higher the chance of getting double gold/exp
[3] Max success rate % per actor can get is 9.99% (999 luck/dex) unless you have scripts that exceed that.
How to Use:
[1] Plug & Play + tags, place the script above Material and below Main
[2] Add <EXTRAEXP> or <extra exp> in the actor's note tag for extra exp based on luck
[3] Add <EXTRAGOLD> or <extra gold> in the actor's note tag for extra gold based on dex
Compatibility:
Part of this script is using the overwrite method, so it will conflict witch scripts that tries to overwrite how the exp/gold is being displayed/earned at the end of a battle.
