Treasure for New Characters
When your new campaign starts at a higher level, a new player joins an existing group, or a current player's character dies and they need a new one, your campaign will have one or more PCs who don't start at 1st level. In these cases, refer to the Character Wealth table (Table 10-10), which shows how many common permanent items of various levels the PC should have, in addition to currency. A single item on this table is always a baseline item. If the player wants armor or a weapon with property runes, they must buy the property runes separately, and for armor or a weapon made of a precious material, they must pay for the precious material separately as well.
These values are for a PC just starting out at the given level. If the PC is joining a party that has already made progress toward the next level, consider giving the new character an additional item of their current level. If your party has kept the treasure of dead or retired PCs and passed it on to new characters, you might need to give the new character less than the values on the table or reduce some of the treasure rewards of the next few adventures.
See the Character Wealth by Level reference table for the full breakdown by level.
