Greetings DDB

I am confused on how to make magical items. The process is not intuitive enough, because I can't see what happens to a character when they get the item equipped, and it takes a lot of clicks to add a single modifier.

Core suggestion:
Give me a dummy character with ability stats all 10, equipped with the weapon, and show me:

• New ability skills
• Additional skills
• Saving throws
• Actions
• HP
• Initiative

When I create something, highlight what is affected.

Further suggestion:
Give me a fancy editor, and a JSON-editor.

• When I create something in the fancy editor, let me see it be highlighted in the dummy at once (no window refresh, but prompt for leaving without saving changes, of cause).
• Tooltip me to see what should happen to make some standard property of different kinds, such as:
  • Extra damage of a specific type
  • Damage with duration (like poisoning)
  • Saving throws
• Allow me to switch into JSON-mode. As example: Dagger of Venom with its current settings:

{
	"Name": "Dagger of Venom",
	"Version": "1",
	"Rarity": "Rare",
	"Base Item Type": "Weapon",
	"Base Weapon": "Dagger",
	"Require attunement": "true",
	"Description": "You gain a  bonus to attack and damage rolls made with this magic weapon. <br/>You can use an action to cause thick, black poison to coat the blade. The poison remains for 1 minute or until an attack using this weapon hits a creature. That creature must succeed on a DC 15 Constitution saving throw or take poison damage and become [condition]poisoned[/condition] for 1 minute. The dagger can't be used this way again until the next dawn.",
	"Additional Information": {
		"Has Charges": "true",
		"Number of Charges": 2,
		"Charge Reset Condition": "Short Rest",
		"Charge Reset Description": "You must perform a short rests to regain your charges",
		"Weight": 1,
		"Magic Item Tags": [
			"Combat", "Damage", "Debuff"
		],
	},
	"Modifiers": [
		{
			"Modifier Type": "Damage",
			"Modifier Subtype": "Poison",
			"Dice Count": 2,
			"Die Type": "",
			"Details": "DCV 15 onstitution Save Negates",
			"Duration Interval": 1,
			"Duration Type": "Round"
		},
		{
			"Modifier Type": "Bonus",
			"Modifier Subtype": "Magic",
			"Fixed Value": 1
		}
	],
	"Conditions": [
		{
			"Condition": "Poisoned",
			"Condition Duration": 1,
			"Duration Unit": "Minute"
		}
	]
}

When I change something, let the Text Editor window validate the input, highlight the errors, update the dummy-view, and highlight what has changed.
