The combat levels of Nail beasts are based on the difficulty of the event chosen: they are level 69 on easy, level 98 on medium, and level 141 on hard. The number of Nail beasts that players encounter depends on the difficulty of the path being taken and can range from anywhere between two level 69 beasts (easy) and six level 141 beasts (hard). On an easy event, players will see between two and three Nail beasts, on a medium event they will see between three and four, and on a hard event anywhere between four and six will appear.
They are not very strong, but they hit very fast with melee (it hits 3 times every attack), and very accurately, even against high-defense armour. Players should keep an eye on their follower's life points, and on their own. One especially effective tactic is to run around, attacking each Nail beast once (targeting any that are attacking your follower first) to attract their attention, then moving to a location that makes them go to a single area. Once in this position, use area of effect abilities so the Nail Beasts will all suffer damage.
Nail beasts drop the tertiary ingredient for the Summoning familiarTalon beast, which yields the highest experience of all pouches. They also drop Nail beast nails, which are used as a secondary ingredient for making Sanfew serum, and possibly a long or curved bone. However, this event usually takes up a large number of inventory space (the charms and nails are unstackable), meaning if this event is not the last one, you'll want a Beast of Burden with good capacity. If one is fighting Nail beasts with the aim of receiving these drops, it is advised to use a high levelled follower (such as level 79 Zachory Bragg or level 80 Dean Vellio) to "scry" for the event. The followers predictions will always be the following for Nail beasts:
Easy event: "I can see strange dark shapes slinking around in the myre ahead. Tread carefully if we go that way."
Medium event: "Be careful if we go this way. I can see some things sneaking around."
Hard event: "Nail beasts! You don't see them much these days. We'll be in for a big fight if we choose to go this way!"
