I know many secrets...
Henzell says...
  1. Attack delay is 10 time units for a melee weapon with base speed 100%. Every 2 levels of weapon skill lower the delay by 1 unit.
  2. A weapon's minimum delay is half of its base delay (rounded down) but no more than 7 (5 for short blades). For example, a club (base delay 13) has minimum delay 6, while an executioner's axe (base delay 19) has minimum delay 7.
  3. see {min_delay}
  4. In 0.26-, monster attack delay with a weapon is the monster's normal attack delay multiplied by 0.5*(1+weapon's base delay). For example, a monster with a scimitar (base delay 1.4) has 1.2x its normal attack delay.
