  Errata: Dungeon Master’s Guide
  This document updates parts of the Dungeon Master’s Guide (5th 
  edition) of Dungeons & Dragons. All the updates here appear 
  in the 10th printing of the book and in the 2018 core rulebook 
  gift sets.
   When updates are added to this document, its version num-
  ber increases, and the word “New” appears before the latest 
  changes.
  Chapter 1
   The Calendar of Harptos (p. 33). Shieldmeet takes place after 
  Midsummer, not Midwinter.
  Chapter 3
   Evaluating Encounter Difficulty (p. 82). In the “Compare XP” 
  step, the second sentence has been replaced with the following: 
  “The threshold that equals the adjusted XP value determines the 
  encounter’s difficulty. If there’s no match, use the closest thresh-
  old that is lower than the adjusted XP value.”
  Chapter 6
   Crafting a Magic Item (p. 129). The first sentence under the 
  Crafting Magic Items table now reads, “An item has a creation 
  cost specified in the Crafting Magic Items table (half that cost for 
  a consumable, such as a potion or scroll).”
  Chapter 7
   Attunement (p. 136). The first paragraph ends with a new sen-
  tence: “If the prerequisite is to be a spellcaster, a creature quali-
  fies if it can cast at least one spell using its traits or features, not 
  using a magic item or the like.”
   Treasure Hoard: Challenge 11–16 (p. 138). In the table, “11–
  12” is now “10–12.”
   [New] Scrolls (p. 139). In the second paragraph, “requires us-
  ing an action” is now “requires the user.”
   Magic Weapons (p. 140). The section ends with a new para-
  graph: “If a magic weapon has the ammunition property, am-
  munition fired from it is considered magical for the purpose of 
  overcoming resistance and immunity to nonmagical attacks and 
  damage.”
   [New] Spells (p. 141). In the second sentence, “lowest possible 
  spell level” is now “lowest possible spell and caster level.”
   Amulet of Health (p. 150). The last sentence now reads as fol-
  lows: “It has no effect on you if your Constitution is 19 or higher 
  without it.”
   Bag of Tricks (p. 154). The second paragraph ends with a new 
  sentence: “The creature vanishes at the next dawn or when it is 
  reduced to 0 hit points.”
   Belt of Giant Strength (p. 155). The last sentence of the first 
  paragraph now reads as follows: “The item has no effect on you 
  if your Strength without the belt is equal to or greater than the 
  belt’s score.”
   Gauntlets of Ogre Power (p. 171). The last sentence now reads 
  as follows: “They have no effect on you if your Strength is 19 or 
  higher without them.”
   Headband of Intellect (p. 173). The last sentence now reads as 
  follows: “It has no effect on you if your Intelligence is 19 or higher 
  without it.”
   [New] Instrument of the Bards (p. 176). The final paragraph is 
  replaced with the following: “You can play the instrument while 
  casting a spell that causes any of its targets to be charmed on a 
  failed saving throw, thereby imposing disadvantage on the save. 
  This effect applies only if the spell has a somatic or a material 
  component.”
   Pearl of Power (p. 184). The first sentence is now two sen-
  tences: “While this pearl is on your person, you can use an action 
  to speak its command word and regain one expended spell slot. 
  If the expended slot was of 4th level or higher, the new slot is 
  3rd level.”
   [New] Rod of Lordly Might (p. 196). The following text is 
  appended to the sentence on button 1: “(you choose the type of 
  sword).”
   Spell Scroll (p. 200). Starting with its second sentence, the 
  first paragraph now reads as follows:
  If the spell is on your class’s spell list, you can read the scroll 
  and cast its spell without providing any material components. 
  Otherwise, the scroll is unintelligible. Casting the spell by 
  reading the scroll requires the spell’s normal casting time. 
  Once the spell is cast, the words on the scroll fade, and it 
  crumbles to dust. If the casting is interrupted, the scroll 
  is not lost.
   Wand of Paralysis (p. 211). The third and fourth sentences 
  now read as follows: “The target must succeed on a DC 15 Con-
  stitution saving throw or be paralyzed for 1 minute.”
  Chapter 8
   Combining Game Effects (p. 252). This is a new subsection at 
  the end of the “Combat” section:
  Different game features can affect a target at the same time. 
  But when two or more game features have the same name, 
  only the effects of one of them—the most potent one—apply 
  while the durations of the effects overlap. For example, if 
  a target is ignited by a fire elemental’s Fire Form trait, the 
  ongoing fire damage doesn’t increase if the burning target is 
  subjected to that trait again. Game features include spells, 
  class features, feats, racial traits, monster abilities, and magic 
  items. See the related rule in the “Combining Magical Effects” 
  section of chapter 10 in the Player’s Handbook.
   Poison (p. 257). The description of ingested poison has a new 
  sentence after the first: “The dose can be delivered in food or a 
  liquid.”
   The other three poison types have new descriptions:
  Contact. Contact poison can be smeared on an object and re-
  mains potent until it is touched or washed off. A creature that 
  touches contact poison with exposed skin suffers its effects.
  Inhaled. These poisons are powders or gases that take effect 
  when inhaled. Blowing the powder or releasing the gas sub-
  jects creatures in a 5-foot cube to its effect. The resulting cloud 
  dissipates immediately afterward. Holding one’s breath is 
  ineffective against inhaled poisons, as they affect nasal mem-
  branes, tear ducts, and other parts of the body.
  Injury. Injury poison can be applied to weapons, ammunition, 
  trap components, and other objects that deal piercing or 
  slashing damage and remains potent until delivered through a 
  wound or washed off. A creature that takes piercing or slashing 
  damage from an object coated with the poison is exposed to 
  its effects.
   Monster Features (p. 280). In the table, “Dive Attack” is now 
  “Dive,” and in the Damage Transfer example, “darkmantle” is 
  now “cloaker.”
  Appendix A

  a sexton.
