67. If your players start a business anyway, you are obligated to have the BBEG threaten it

66. Under no circumstances should you let your players start an in-game business unless your table is one of accountants

65. Esp if you're doing 64: give time for Downtime, and make it a currency to spend. Think of it like vacation days for adventuring

64. You should give your players magic items that they can't currently use (due to spellcasting restrictions or class) to provide potential opportunities for new development direction

63. literally just give your wizard some spells scrolls. wizards love spell scrolls

62. An NPC's potential for betrayal is an absolute value of how likable they are. Super friendly and helpful? Absolutely the BBEG in disguise. Awful and annoying? A constant threat. Bland and forgettable? probably safe

61. If you have a familiar or pet, it is safe until the moment you ask me "can my dog attack them?" and then it's Fair Game

60. Players will read the first half of the first 3 words of a 2-paragraph feature and then make up the rest. Just actually read how sneak attack works, I'm begging you

59. The reason why your casters are overpowered is because you run like 1 combat an in-game day. Try 5 and see how well that works.

58. (5e) just make the rule "1 non-cantrip spell per turn" or just let it ride the bonus action rule is so dumb and bad
