Advanced spell customization
Advanced spell customizations provide unique or otherwise different messaging when a character CASTs a spell. This includes when using INCANT to both PREPARE and CAST a spell with a single command. Similar to custom spell preps, advanced spell customizations provide different effects depending on the spell cast. Certain merchants can give you advanced spell messaging customized to your character. Pre-written advanced spell customizations are also available at various festivals, pay events, and at Bayview Villa on Mist Harbor. An advanced spell customization is a delayed service when the player is writing their own.
For bolt spells, advanced spell customizations provided different bolt messaging when the spell is cast at a target. For other spells, the advanced spell customization changes what the magical effect created by the spell looks like, such as with a new plant summoned when using Tangle Weed (610), or different food with its own flavor messaging when using Manna (203), or a unique portal appearance with its own open/close messaging when using Familiar Gate (930).
Some spells, such as Fire Spirit (111), may have different types of spell customizations applied. For this spell, its attack bolt messaging when casting the spell at a target is one type of advanced spell customization. The other type is the description of a firework made when the spell is cast without a target. Having a custom firework will only impact the spell when the end result is a firework. A custom firework will not impact the bolt attack form of the spell.
Many advanced spell customizations are part of the Player Customization System, which is managed via the CUSTOM verb. Not all spells are compatible with the Player Customization System. Those spells that are not managed via CUSTOM can only have one set of messaging at any given time. Applying new custom messaging to spells not part of the Player Customization System will overwrite the previous messaging available, whether it was default or another advanced spell customization.
Each type of advanced spell customization has its own set of rules when creating fully custom messaging.
Examples of pre-written advanced spell customizations can be viewed in the character customizations category.
Note: Advanced spell customizations encompasses only the messaging associated with the results of casting a spell; it does not change how the spell looks when it is prepared. Custom spell preps impact how messaging apperas when a spell is prepared and before it is cast, including if the spell is just prepared and never cast.
