Holds encounter templates — parametric generators that describe how to build a random encounter rather than a fixed one. A template specifies how often it fires, where it applies, and what monsters, NPCs, traps, items, and treasure may appear, along with the dice that decide how many of each show up.

Data in this file includes

• Identity — The template's name, a prose description, and a free-form terrain description.
• Selection Criteria — The filters that decide when the template applies: its frequency (from exempt through very rare, rare, uncommon, to common), a hit-dice band matching the power level of the party, and a monster-type filter.
• Encounter Mode — A three-way exclusive setting marking the template as lair-only, wandering-only, or both.
• Climate & Terrain — Yes/no flags for the climates (arctic through tropical) and the many terrain environments (aerial, forest, desert, ocean, swamp, subterranean, and so on) in which the encounter can occur.
• Treasure Amounts — The amount granted for each standard treasure type (A–Z).
• Monster Properties — One or more rows describing groups of monsters that may appear. Each row carries selection dice and additional-monster dice (number, sides, multiplier, and adds), dependency and and/or selector flags, a percentage chance, for-every / beyond thresholds, the fixed and picker- chosen monster names, an alternate "defined as a monster-type" reference with its display bitmaps, and an inline list of the monsters that appear.
• NPC Properties — One or more rows describing groups of NPCs, structured like the monster rows: selection and and/or dice, dependency flags, percentage and threshold values, and a dependent-monster/type reference. Each row also embeds a primary NPC and an alternate and/or NPC — each given by name, race, and a five-slot multi-class with per-slot levels — plus an inline list of additional NPCs in the same form.
• Item Properties — One or more rows describing items that may appear. Each row carries a percentage chance, number-of-items dice, a currency type (platinum / gold / silver / copper) with its own amount dice, dependency and for-every / beyond settings, embedded references to a dependent monster, monster-type, and the actual item, a list of monsters whose count is doubled, and inline lists of escorting monsters and per-item monsters (each with number-appearing dice and an embedded monster).
• Traps — The traps that may be part of the generated encounter.
