RuneScape players who are in the pincers unlock crewman Oxhead and Horseface when they travel to the shambling lair.
The shambling lair voyage requires 10,000 morale, combat, and seafaring to do. RuneScape players who are just entering the pincers can usually get over 70% on it using judges of dice and ship boosts. If failed, it can be attempted again. If partial, the island should be unlocked but no oxhead and horseface shows up on the next crew roll.
Oxhead and horseface starts out with a base of 600 morale, combat, and seafaring. With one pincers run, it levels to three, with 780 in each stat. After a few more trips it is a formidable level five at 900 in each stat, a stat a judge of dice needs to be level 10 to achieve.
Also the oxhead and horseface counts as a different type of crew. When using with a judge of dice, this gives it an additional 100 in each stat compared to using a second judge of dice.
Oxhead and horseface amounts to half the stats of a pincers crew on single trait missions, is equal on two trait missions, and is 150% of a pincers crew on three trait missions. Also, on two trait missions it allows for balancing the two traits if necessary plus an additional 100 in each trait when stacked with a judge of dice, as it is a different type of crew.
RuneScape players will want to reduce the amount of judges of dice as they hire oxhead and horsefaces, although it is good to get rid of sea witches first as their base stats are lower. Ultimately, for every four ship run, one to four judges of dice will be used. Therefore, three is an ideal number to have. The reason three instead of two is, should a single trait mission roll up and there only be four crew of that trait, the judge of dice stat as well as its 100 boost will be better than having no crew in that slot.
Ideally there will be between three and five oxhead and horsefaces alongside the judges of dice. The number of single trait and hybrid trait crew should be taken into account while planning on a voyage which crew to use.
