Leveling Up

Use these guidelines to raise an existing monster by one or more levels.

  1. Raise its attack bonuses and defenses by 1 per added level.
  2. For damage, hp, and related special abilities (like healing), multiply the monster’s stats accordingly:
Levels Added Damage Multiplier
+1 level x 1.25
+2 levels x 1.6
+3 levels x 2.0
+4 levels x 2.5
+5 levels x 3.2
+6 levels x 4.0

Monster Creation

Initiative

Establish a monster’s initiative bonus by adding its level to a modifier between –1 and +9.

Modifier Speed Example
–1 Super-slow and utterly clumsy oozes, zombies
+0 Slow and clumsy animated statues
+1 Awkward or small city guards, dire rats
+2 Average hellhound, human thug
+3 Just above average derro sage
+4 Quick owlbear
+5 Fast wyvern
+6 Really fast gnoll ranger
+7 Fast like a fast PC ogre mage
+8 Blindingly fast rakshasa
+9 Competing with the rogue  

Attack Bonus

Add or subtract 1 to adjust how accurate a monster is.

Strike Damage

Orient yourself around the average damage for a monster’s attack at any given level. When it comes to large (or double-strength) or huge (or triple-strength) monsters, you don’t have to put all their damage into one strike. Split damage up into smaller attacks or use conditional follow-up attacks.

HP & AC

Use the defense numbers as the top-end rather than the baseline unless you want the difficulty to scale up.

Better Defense/Lesser Defense

Make either PD or MD better than the other, in general.

Fear Threshold

If the monster has a fear ability, it’s the number of hit points where creatures are dazed (–4 attack) while engaged with the monster and can’t use the escalation die. It’s based on level, so that higher-level monsters are more fearsome.

Stat Adjustments

Ad hoc adjustments work fine when limited to adjustments of 1 or 2 points. If you raise a couple scores, drop a couple others.

If you want to add a full level to a monster

  • and you only want to boost its attack: Give the monster a +6 attack boost.
  • and you only want to boost AC: Give the monster a +6 AC boost.
  • and you only want to increase the monster’s hit points: Double the monster’s hit points.
  • and you only want to increase the damage the monster deals: Add a second attack or ongoing damage.
  • and you only want to increase every stat: Add +1 to attack, +1 to all defenses, multiply its damage output by 1.25, and multiply its hit points by 1.25.

Powers to Avoid

Avoid defensive powers that make it harder for the monsters to be killed unless there’s an offense to unlock the defense.
