Bestiary & Conversions

Bestiary

The following Guidelines can help convert statblocks to your system.

d20 Rolls

In games where NPCs roll their Checks and Saves, add their Hit Dice (HD) count to their d20 roll if they are good with the Check. Save DCs: Use Normal Difficulties (12 to 13) for Save DCs forced by NPCs

Hit Points

Old School: Roll a number of d8s equal to its HD for Hit Points, or use the assumed HP in their statblocks. Contemporary: Use the assumed HP and add the HD number to it. For example, an HD: 4 (18 HP) Being would have 18 + 4 = 22 HP.

Attacks & Spells

Roll High: Result = d20 + HD THAC0: THAC0 = 20 - HD

Damage

Old School: No change. Contemporary: Damage + HD

Morale (MRL)

Enemies make Morale Checks at the following times during a Combat:

• The first death in their Group.

• Their HP is at half or less, or half their Group is Incapacitated.

To check Morale, roll 2d6 and consult the Group’s Leader’s statblock. If the 2d6 result is higher than its Morale, the Group fails and either retreats or surrenders.
