Here is how to convert from D&D to HeroQuest for quick snappy combat.
Movement is set to 10, which is standard for fodder enemies, and with a DEX of 15 is appropriate.
Attack is STR modifier, minimum 1. Since they get a -2 mod, their attack is 1, which is appropriate.
Defend is DEX mod or Armor (as appropriate. DEX mod is +2 so their defend dice pool is 2.
BP is CON mod, minimum 1, so 1.
MP is INT or WIS mod (whichever is higher) minimum 1.
Converted abilities below the stats.
