Adjust the XP Total by Number of Monsters and Party Size

Source: R/xp_cost.R
xp_cost.Rd

In the 2014 version of fifth edition Dungeons and Dragons, encounters are more difficult than the total of the monsters' experience points (XP). Both the number of monsters making attacks and the number of players attacking those creatures can affect the difficulty of an encounter. The 2014 Dungeon Master's Guide (DMG) accounts for this by providing an XP multiplier for given party sizes and numbers of monsters. This function accepts the unmodified total of the monsters' XP and adjusts this as specified in the DMG without the pain of the tables in that book. For the 2024 version, the XP cost is exactly equal to the total monster XP so this function will return a warning and whatever value is passed to the `monster_xp` argument if the 2024 version is specified.

Usage

xp_cost(
  monster_xp = NULL,
  monster_count = NULL,
  party_size = NULL,
  ver = "2014"
)
