Help Applying AppliesRandomModifier to only some GameModifier Effects?

Making a lot of progress with this spell, SO close to figuring it out!

from Elemental Forums

I'm trying to create a Strategic spell that (1) randomly transforms a friendly shard into either a Fire Shard or a Death Shard AND (2) cannot be used more than once on the same shard.

I've gotten (1) to work as an independent spell, by using <AppliesRandomModifier> to choose between two separate <GameModifier> tags.  

I've gotten (2) to work as an independent spell, thanks to Heavenfall's really clever solution, bless his heart:  Make the spell also change the terrain type beneath the shard, and restrict the spell from being cast on that terrain type.  This, too, works perfectly---the spell can change the terrain type while changing the shard, and doing so prevents the spell from working again on the same shard.

Problem: Getting (1) and (2) to work together in the same spell.  

If I simply add the terrain-changing effect from (2) into (1) as a third <GameModifier>, it becomes affected by <AppliesRandomModifier> along with the two Shard-change options.   (So, instead of a 50/50 chance to create a Fire/Death shard, with a 100% chance to change the terrain, I get a 33/33/33 split between creating a fire shard, creating a death shard, or changing the terrain.)

So, I'm looking for a way to restrict the scope of <AppliesRandomModifier> to the two shard-changing effects, and ensure the spell always applies the terrain-change effect.

Right now, I'm trying to solve this by breaking (1) and (2) into two independent "Sub-Spells", then having the main spell cast both of them via the UseSpell attribute.  Unfortunately, this doesn't work:  When I cast the spell, nothing happens but for the particle effect.

Here are the three spells:

Main Spell:

Code: xml
  3. &lt;SpellDef InternalName="PromiseOfAsshai"&gt;
  4.     &lt;DisplayName&gt;Promise of Asshai&lt;/DisplayName&gt;
  5.     &lt;Description&gt;Channel the essence of Asshai into the land of Elemental, randomly transforming a shard in your empire into a Fire shard or a Death shard.&lt;/Description&gt;
  6.     &lt;Image&gt;S_PromiseOfAsshai_Painting.png&lt;/Image&gt;
  7.     &lt;IconFG&gt;S_PromiseOfAsshai_Icon.png&lt;/IconFG&gt;
  8.     &lt;AutoUnlock&gt;1&lt;/AutoUnlock&gt;
  9.     &lt;SpellType&gt;Strategic&lt;/SpellType&gt;
  10.     &lt;SpellClass&gt;Other&lt;/SpellClass&gt;
  11.     &lt;SpellSubClass&gt;Other&lt;/SpellSubClass&gt;
  12.     &lt;SpellTargetType&gt;RegularShard&lt;/SpellTargetType&gt;
  13.     &lt;SpellBookSortCategory&gt;World&lt;/SpellBookSortCategory&gt;
  14.     &lt;SpellBookSortSubCategory&gt;Other&lt;/SpellBookSortSubCategory&gt;
  15.     &lt;SpellTargetZOCType&gt;Friendly&lt;/SpellTargetZOCType&gt;
  16.     &lt;Prereq&gt;

  23.         &lt;Attribute&gt;UseSpell&lt;/Attribute&gt;
  24.         &lt;StrVal&gt;PromiseOfAsshai_ShardChange&lt;/StrVal&gt;
  25.         &lt;Provides&gt;Channel the essence of Asshai into the land of Elemental, randomly transforming a shard in your empire into a Fire shard or a Death shard.&lt;/Provides&gt;
  26.     &lt;/GameModifier&gt;

  28.         &lt;ModType&gt;Unit&lt;/ModType&gt;
  29.         &lt;Attribute&gt;UseSpell&lt;/Attribute&gt;
  30.         &lt;StrVal&gt;PromiseOfAsshai_AshenLand&lt;/StrVal&gt;
  31.         &lt;Provides&gt;Channel the essence of Asshai into the land of Elemental, randomly transforming a shard in your empire into a Fire shard or a Death shard.&lt;/Provides&gt;
  32.     &lt;/GameModifier&gt;

  34.         &lt;Resource&gt;Mana&lt;/Resource&gt;
  35.         &lt;Amount&gt;50&lt;/Amount&gt;
  36.     &lt;/SpellResourceCost&gt;
  37.         &lt;!-- Not sure if "BarredTerrain" works here, but I&#39;d already done it this way when I saw that tag even existed, so... yeah. --&gt;

  33.         &lt;SnapToTerrain&gt;1&lt;/SnapToTerrain&gt;
  34.     &lt;/SpellDefEffect&gt;
  35. &lt;/SpellDef&gt;

I suspect this has something to do with "UseSpell" not being intended for use in this manner (it only appeared on consumable items).  But I couldn't find any other attributes that could call another spell outside of tactical combat.

Anyone know how I could pull this off?  It's the final piece of the puzzle!

Hi Eunomiac. Welcome to the Modding forum!

Thank you!  I just discovered this forum today, after wandering around the FE Modding forum and wondering why it was so quiet in there ;)

Your solution works far better than anything I've tried, but it introduces a new hiccup:  The goodie hut it places needs to be walked over before it becomes the Death/Fire shard.  Is there any way to make a Goodie Hut automatically "pop" on generation?

(And it's gotta be said, your solution---as have many of the solutions to my various problems presented by the fine folk 'round these parts---blew my mind a bit, not gonna lie.  Goodie Huts!  Never would have thought of that :) )

Thanks again, and if you've got an idea for auto-popping that goodie hut, you'll be my hero of the week!

Works PERFECTLY!  Even better than I'd hoped---the <TileDesign> tag for the Goodie Hut lasts a turn or so, which is just enough time to create a nifty temporary effect to represent the shard waffling between light and shadow before "choosing" when the Goodie Hut auto-pops.
