Have your pet deal the finishing blow against 150 Wyvern-type creatures during Earth Weather or on Earth's day.
- Note: Each kill on Earthsday = 1 kill. Each kill with Earth weather on any day present = 5 kills.
- Earth weather and Earthday = 6 points
If you wish to rely on weather for this trial, The only area option is Gustav Tunnel, hunting Typhoon Wyverns, which spawn in several locations on the second map. However the spawns are rather spread out, with many undead monsters roaming around. The mobs are pretty easily handled solo, although dropping into yellow HP in a bad spot can get you swarmed, and the amount of mobs attacking may overwhelm you.
