Reddit reviews Pathfinder Society Face Cards Deck (Pathfinder Cards)

• A box with 5x5 cards containing all my notes
  
• Dice. Soooo many dice
  
• Minis, if needed
  
• A pen
  
• The book I currently need to use, either the MM, DMG or a campaing book
  
• A tablet with a reference app
  
• A paper block to write down
  
• A stack of small tents with numbers on them, to display initiative
  
• A bunch of character cards, such as this

If you can find them some like this might help with inspiration. You don't have to show these to the player just draw a card and use what you see to guide your description.
