Ripscale is a level 39 rare crocolisk that can be found in Dustwallow Marsh. He spawns in six different locations and patrols within each one. He does not move between the patrol areas once spawned. I have indicated each location in red on the map below.
He is also desirable as a hunter pet for lower level hunters as he is the only tamable crocolisk in this color under level 82. The only other tamable crocolisks in game that share Ripscale's model and color are the level 82-83 Neferset Crocolisks in Uldum.
Ripscale can be found with NPCScan. You will need to add it, his NPCScan ID is 14233.
You can also use this macro to help find and tame him:
/cast Tame Beast
I'm not sure on his exact spawn timer, but before Cataclysm it was between 10 - 16 hours. I believe that it is significantly shorter than that now.
There are a total of five rare tamable hunter pets in Dustwallow Marsh. All of them are:
- Darkmist Widow, level 37 black & red spider
- Dart, level 37 orange raptor
- Hayoc, level 37 white wind serpent
- Oozeworm, level 38 yellow worm
- Ripscale, level 39 crocolisk
