/*  Usage: /:DetectTraps title="<title>"" dice=<dice> adds=<adds> type=<type> adiv=<divisor> rsize=<rsize> attrib=<attribute> difmod=<difficulty> skill=<skill> detectwith=<detectWith> detectdif=<detectDif> tag=<trapTileTag>
   Title - name to display on dialog
   Dice - dice of damage per energy point; may be a fraction
   Adds - modifier to each die of damage, zero if none
   Type - Damage type (cr, cut, burn, etc...)
   Divisor / Radius - Reduce DR by (x) or spread to Radius hexes
   Attribute - DX, ST, DX, IQ, Will, etc
   Difficulty Modifier - Trap difficulty
   Skill - Skill name Precheck to evade, i.e. Acrobatics
   Detect With - Skill or Attribute to detect the trap, i.e. Perception
   Detect Difficulty - Difficulty to detect trap; default to trap difficulty
   Trap Tile Tag - Tagger tag name for the tile to trigger, default to SpikeTrap01
  
   DetectTraps lets you auto-detect a trap;
   Required Macros: DetectTraps, EvadeTrap, ResistEffect
   Optional Macros: PoisonSpray, YellowMoldSpores, AlchemistFire, SpikeTrap100x100px, SpikeTrap160x160px
   Add your own special effects to this recipe book.

 Example chat commands to use in MATT for various trap types (adjust to fit your own trap designs):

    /:EvadeTrap title="Pitfall Trap" dice=3 adds=3 type=pi++ rsize=2 attrib=DX difmod=-4 skill=Acrobatics detectwith=!PER! tag=PitfallTrap01
	/:EvadeTrap title="AlchemistFire" dice=4 adds=4 type=burn rsize=3 attrib=DX difmod=-5 skill=Jumping detectwith=!PER! detectdif=-8 tag=BuxlanTorrapStatue05

  Difficulty Examples:
	- Evade Crude "Spike Trap" DX+2
	- Evade Basic "Spike Trap" DX
	- Evade Devious "Spike Trap" DX-4
	- Evade Vicious "Spike Trap" DX-6
    - Evade Deadly "Spike Trap" DX-8
	- ["Evade Deadly Spike Trap DX-8"/DX-8 You Evade! /else [3d+3 (2) pi++]
