These are 20 Conan Tiles (in English and French versions) as well as Pawns for Leaders, Monsters, and Minions from the game The Others: 7 Sins. The art from that game was also by Adrian Smith, the same artist as Conan. These are useful for creating custom Conan scenarios featuring Demonic forces for the Overlord.
Some ideas for special rules for the demon minions (in addition to their ability icons)...
Children of Ajujo -- Stench: Heroes in the same space regain 1 fewer gem from fatigue to reserve at the start of their turn.
Hags of Hell -- Distraction: Heroes in the same space cannot make any ranged attacks.
Horrors -- Terror: Heroes must use 1 extra movement point to enter their space.
Crawlers -- Pounce: When attacking webbed Heroes, add 1 extra yellow die with reroll to their attack.
Sons of Nergal -- Acid Blood: When killed, cause area attack of 1 orange and 1 yellow die against any Heroes in their space.
Screamers -- Shriek: Heroes in the same space must pay 1 extra gem to cast each spell.
Rippers -- Shred: When attacking Heroes wearing armor (passive defense), reduce Heroes' passive defense by 1.
