Recaps & Roundups part 6: D&D Correction Sheet

The second printing of the original Dungeons & Dragons set - released in January of 1975 - included a sheet with some corrections to the rules. It was also present in the third printing, released in April 1975. Mostly it clears up some typos, but it also makes some rules changes and clarifications that I thought I'd note.

• In the first printing, the sleep spell affected 1d6 creatures of 4 Hit Dice. It's changed here so that it now only affects a single 4 HD creature.
• The Hit Dice for skeletons and zombies were unclear in the first printing. They were shown as having HD 1/2, which could have meant two things: either both creatures had half a Hit Die, or skeletons had 1 and zombies had 2. It's changed here so that skeletons get half a Hit Die and zombies get 1.
• Balrogs in the first printing did just 2d6 damage with their flaming bodies. It's corrected here so that they can now do 3d6 or 4d6 depending on size.
• It wasn't mentioned in the first printing that gargoyles can only be damaged by magic weapons, but that rule is added here.
• Similarly, a rule is added here so that lycanthropes can only be damaged by silver or magic weapons.
• Elementals are changed here so that only magic weapons can damage them as well.
• In the first printing, all spell scrolls are for magic-users. This sheet changes the rule so that a quarter of scrolls will feature clerical spells.
• In the first edition, the potion of heroism was quite literal, in that it transformed a normal man into a Hero (a 4th level fighter). This sheet adds some lines so that the potion is useful for characters of levels 5+.
• This sheet clarifies that a spell written on a scroll can only be used once before it disappears, something that wasn't mentioned in the first printing.

I usually try to rationalise these kinds of rule changes for this project, but in this case I'm going to treat them as exactly what they are: errata. These are all things that should have been in the rules in the first place, so I feel no need to explain them.
