In ADOM versions prior to 1.2.0 Prerelease 8[1], traps are generated in a certain sequence, progressing from left to right and top to bottom. So traps found by moving diagonally towards right upper corner would be on the same line, while moving on right down line will cause jumps per two numbers. 1. * Teleportation 2. * Water 3. * Fireball 4. * Pit 5. * Light 6. * Corruption 7. * Stone block 8. * Alarm 9. * Arrow 10. * Acid 11. * Pit with vipers 12. * Spears The latest versions [after pre8] randomize traps, making this table useless.
