To find the Rageclaw the player must have spoken to the "Huntmaster" in Phon Coast and defeated Thalassinon, which will trigger the start of the Rare Game quest. To spawn the Rageclaw, once the player enters Piebald Path, they cannot kill any enemies nor let any enemies be Cannibalized. After sixty seconds, the Rageclaw will spawn near the exit opposite the one the player entered through.
Rageclaw is a particularly tough foe. It can be defeated easily, but if the player wants to test their strength Rageclaw is a great enemy to fight. It can be strengthened by luring it to other enemies to Cannibalize. Rageclaw is capable of using Cannibalize numerous times.
When it gets to a very high level it can damage a character for 9,999 HP with a single attack, though its Pulsar Wave does not do damage for 9,999 HP. The Rageclaw is very fast and a good idea is to cast Reverse on a character. Physical attacks (apart from damage inflicted by Guns) become useless if its level is high enough, then the party must rely on Magicks or Quickenings to defeat it.
