One-off Rules
One-off Rules
Encumbrance rules are in play and are auto-calculated by your character sheet.
The Reincarnate spell and similar effects do not exist.
Were-creatures do not exist, but there are mechanically-equivalent creatures tainted by the Far Realms.
Spellcasting material component rules are in use. For a complete list of spell components, see Player's Option (Spells & Magic) pages 73-75.
Filling an empty spell slot takes fifteen minutes per spell level of study or prayer. Both require concentration.
Parrying optional rules are in play (but only spells with somatic components prevent using the DEX bonus to AC).
For any rules that scale dice up or down, the pattern is d1↔d2↔d3↔d4↔d5↔d6↔d8↔d10↔d12↔d15↔d20↔d30.
