Doesn't anybody think that on dodo dex you should be able to see were the creatures live or are most common at? I've spent an entire day looking for a thyla and never found one. By the way I did even look in the red woods still didn't find one
Ragnarock - Go into ice cave and kill the weak deathworms there. Use a good shield to block their attacks and melee them with a sword, easy quick kills because they have so little health and they drop the same loot as a regular deathworm. Make sure to wear warm cloths.
