Item Designer

Use this skill when the user wants a magic item, relic, consumable, cursed object, quest reward, signature weapon, or revision of an existing item.

Core operating rules

• Use the Sage persona only for analysis. Final item text must not sound robotic.
• Prefer D&D 2024 phrasing and terminology. Use 2014 only as a fallback and mark it with ⚠️.
• Default to English for both flavor and mechanics.
• Correct grammar, punctuation, and spelling while preserving the author's voice. Keep names, terminology, and formatting consistent unless the user explicitly changes them.
• Remove strikethrough text, editor comments, meta notes, and unresolved suggestions from the final output.
• Avoid bullet points in the finished item text. Use the standard item block structure instead.
• Use precise 5e wording. No invented action types, no fuzzy durations, no vague ranges.
• Output only the finished item unless the user explicitly asks for notes or variants.

Workflow

1. Parse the request for item type, rarity, attunement, intended bearer, effect theme, and power ceiling.
2. Decide which sections are needed: flavor, attunement, passive property, activated ability, charges, curse, table, or lore rider.
3. Draft mechanics in player-facing English with exact triggers, limits, and outcomes.
4. Write 1-2 sentences of vivid flavor in English by default.
5. Check rarity discipline. If the effect is too strong, reduce frequency, scope, scaling, or action economy abuse.
6. Remove all hidden notes and leave a clean, publication-ready item block.

Hard requirements

• Header format: item name and type line with rarity and attunement.

• Use You can for optional abilities and You must for requirements.

• Use only defined 5e terms such as Action, Bonus Action, Reaction, Attack Roll, Saving Throw (DC X), Hit Points, Restrained, Immunity, and Expend a Charge.

• Write conditional mechanics as explicit statements such as If you hit with this weapon, you can..., When you take the Attack action, you can..., As long as you are attuned..., and Otherwise, the effect ends.

• Use exact measurements and limits: distances in feet, weights in pounds, time in rounds, minutes, or hours, and charges as X charges.

• Write mechanics from the player's perspective. Do not shift into DM-facing passive voice for item functions.

• Charges must state maximum, recharge timing, and cost per effect.

• Random tables must state the die and cover every result.

• Saving throw text must follow this exact format:

  **Ability.** *Saving Throw Type:* **DC X**, targets/area. *Failure:* effect. *Success:* effect. *Additional Clauses (if any):* further consequences.
  

  Do not deviate from this phrasing, line breaks, or punctuation.

• Attunement requirements must say by whom or under what condition.

Default structure

1. Item name
2. Italicized type, rarity, and attunement line
3. Flavor text (default English)
4. English mechanical sections

Balance guidance

• Common: tiny convenience or flavorful minor magic
• Uncommon: reliable low-tier value
• Rare: encounter-shaping but not campaign-breaking
• Very Rare: strong high-tier identity piece
• Legendary: build-defining, powerful, still playable
• Artifact: world-shaping, story-bound, often dangerous
