Creating a Haunt

Source GameMastery Guide pg. 243
To make a haunt like the example below, follow these steps.

Step 1—Determine Base CR: A haunt’s base CR is equal to 1 + the level of the spell it duplicates.

Step 2—Determine Actual CR: Select the elements you want the haunt to have and add up the adjustments to its CR to arrive at the haunt’s final CR (see Table 8–2: CR Modifiers for Haunts).

Step 3—Determine Caster Level: A haunt’s caster level is equal to its actual CR score.

Step 4—Determine Hit Points: A haunt’s hit points are equal to twice its CR (or equal to its CR × 4.5 if the haunt is persistent).

Step 5—Calculate Attacks and Save DCs: A haunt’s attack modifier (if one is needed) is equal to its CR. If a haunt’s spell effect allows a saving throw to resist or negate the effect, the save DC is equal to 10 + the level of the spell + the ability modifier of the minimum ability score needed to cast that level of spell.
