{
	"projectile": [
		{"minimumAngle": 0 ,"defName":"C20SPX4"},
		{"minimumAngle": 0.60 ,"defName":"C20SPX3"},
		{"minimumAngle": 0.90 ,"defName":"C20SPX2"},

	],
	"hit":["C20SPX"],
	"affect":[{"defName":"C03SPA0", "verticalPosition":"bottom"}, "C11SPA1"]
}
```

# Spell level base format

Json object with data common for all levels can be put here. These configuration parameters will be default for all levels. All mandatory level fields become optional if they equal "base" configuration.

## Example

This will make spell affect single target on all levels except expert, where it is massive spell.

``` javascript

"base":{

   "range": 0
},
"expert":{
"range": "X"
}
```

# Spell level format

``` javascript

{
	//Mandatory, localizable description
	//Use {xxx} for formatting
	"description": "",


	//Mandatory, number, 
	//cost in mana points
	"cost": 1,

	//Mandatory, number
	"power": 10,

	//Mandatory, number
	"aiValue": 20,

	//Mandatory, flags structure //TODO
	// modifiers make sense for creature target
	//
	//
	"targetModifier":
	{
		"smart": false,	//true: friendly/hostile based on positiveness; false: all targets
		"clearTarget": false,
		"clearAffected": false,
	}
	//Mandatory
	//spell range description in SRSL
	// range "X" + smart modifier = enchanter casting, expert massive spells
	// range "X" + no smart modifier = armageddon, death ripple, destroy undead

	"range": "X",

	//DEPRECATED, Optional, arbitrary name - bonus format map
	//timed effects, overriding by name
	"effects":
	{
		"firstEffect": {[bonus format]},
		"secondEffect": {[bonus format]}
		//...

	
	},
	//DEPRECATED, cumulative effects that stack while active
	"cumulativeEffects":
	{
		"firstCumulativeEffect": {[bonus format]}
		//...

	},
	"battleEffects":
	{
		"mod:firstEffect": {[effect format]},
		"mod:secondEffect": {[effect format]}
		//...

	}
}
```

# Configurable battle effects

**If spell have at least one special effect it become configurable spell and spell configuration processed different way**

## Configurable spell

Configurable spells ignore *offensive* flag, *effects* and *cumulativeEffects*. For backward compatibility *offensive* flag define Damage effect, *effects* and *cumulativeEffects* define Timed effect.

## Special effect common format

``` javascript

"mod:effectId":{

"type":"mod:effectType", //identifier of effect type
"indirect": false, // effect will be deferred (f.e. land mine damage) 
"optional": false // you can cast spell even if this effect in not applicable

//for unit target effects
"ignoreImmunity" : false,
"chainFactor" : 0.5,
"chainLength" : 4

//other fields depending on type
}
```

## catapult

``` javascript

"mod:effectId":{

"type": "core:catapult"
	"targetsToAttack": 1, //How many targets will be attacked by this
	"chanceToHitKeep" : 5, //If it is a targeted spell, chances to hit keep
	"chanceToHitGate" : 25, //If it is a targeted spell, chances to hit gate
	"chanceToHitTower" : 10, //If it is a targeted spell, chances to hit tower
	"chanceToHitWall" : 50, //If it is a targeted spell, chances to hit wall
	"chanceToNormalHit" : 60, //Chance to have 1 damage to wall, used for both targeted and massive
	"chanceToCrit" : 30 //Chance to have 2 damage to wall, used for both targeted and massive
}
```

## Clone

Configurable version of Clone spell.

``` javascript

"mod:effectId":{

"type": "core:clone"

"maxTier" : 3//unit tier
}
```

## Damage effect

If effect is automatic, spell behave like offensive spell (uses power, levelPower etc)

``` javascript

"mod:effectId":{

"type": "core:damage",
"killByCount": false, //if true works like Death Stare
"killByPercentage" : false, //if true works like DESTRUCTION ability

//TODO: options override

}
```

## Dispel

"firstBonus":{[bonus format]}
//...
}
}
```

# Additional documentation

## Targets, ranges, modifiers

- CREATURE target (only battle spells)
 - range 0: smart assumed single creature target
 - range "X" + smart modifier = enchanter casting, expert massive spells
 - range "X" + no smart modifier = armageddon, death ripple, destroy undead
 - any other range (including chain effect)
  - smart modifier: smth like cloud of confusion in H4 (if I remember correctly :) )
  - no smart modifier: like inferno, fireball etc. but target only creature

- NO_TARGET
 - no target selection,(abilities, most adventure spells)

- LOCATION
 - any tile on map/battlefield (inferno, fireball etc.), DD also here but with special handling
 - clearTarget - destination hex must be clear (unused so far)
 - clearAfffected - all affected hexes must be clear (forceField, fireWall)

- OBSTACLE target
 - range 0: any single obstacle
 - range X: all obstacles
