Sigilry operates as a comprehensive digital orrery for spellcasting characters, processing spell preparation rules, slot consumption, and concentration mechanics according to fantasy RPG systems. The app architecture separates spell data into filterable axes including school, level, components, casting time, range, duration, and ritual availability.
Every caster record maintains independent tracking of standard spell slots and pact magic pools, calculating available resources based on class level and rest cycles. The concentration system monitors active spell duration, counts combat rounds, and prompts for damage-triggered Constitution saving throws using your spellcaster's modifiers.
The compendium engine cross-references spell statistics against character preparation limits, distinguishing between prepared casters like Clerics and known-spell casters like Sorcerers. Custom spell authoring stores user-generated magical effects with identical stat tracking as core compendium entries, integrating seamlessly into search and filter operations.
Browse the full catalog of arcane and divine magic with detailed statistics for every incantation. Search across seven independent filtering axes to locate exactly the spell your character needs mid-session.
Manage standard spellcasting slots and pact magic independently within a single caster record. The app calculates available resources based on class levels and tracks consumption across short and long rest cycles.
Active concentration spells display with round counters and automatic damage save calculations. The system reminds you when concentration breaks and tracks multiple casters' focus simultaneously during combat encounters.
Build records for every spellcaster at your table including player characters, NPCs, and monster casters. Track initiative order, hit points, condition tags, and spell effects for the entire cohort from one interface.
Design homebrew spells and magical items with the same stat tracking as compendium entries. Your custom creations integrate into search filters and preparation lists, expanding your arcane library beyond core rules.
Maintain session notes with embedded photos and cross-linked spell references. Document magical discoveries, track recurring enchantments, and build a campaign grimoire that connects narrative moments to mechanical rules.
Sigilry emerges from direct experience running high-level spellcaster campaigns where manual spell management interrupted game flow. The development priority centered on reducing table friction while preserving the visual atmosphere of magical scholarship. The marble and lightning aesthetic reflects the fusion of ancient arcane tradition with contemporary mobile interface design, treating spell preparation as a ritual worthy of ornate presentation rather than clinical bookkeeping.
