If you want a hint to start the quest: In the Snowy Village there is an npc that is really unlucky.
I helped out a fishing NPC, but nothing came out of it. Nor could I find another NPC.
Yeah wolves ability is rather different. Once you have wolf form Rare Enemy encounters can spawn at night. Those enemies often are the best to get either exp or materials. If your fortunte is high enough those rare encounters even sparkle golden on the overworld making them easy to spot. But without that they look like every over enemy on teh overworld or else it wouldn't be a "rare" encounter.
It is then quite badly conveyed that you need to actually fight to trigger the rare encounters which do not sparkle.
It is related to the other hidden secret tf, you need to visit that place with the right form and the unique tf item "Golden Jade". You probaly refering to the Golden Jade. Looking near the abandoned lab might be a good start.
I did manage to find the item (though a "fragile" rock costing 200 TP isn't fragile. Maybe reframe it as "tough, but not tough enough". But I couldn't find anything looking around the desert and the salamander places. What is the next step?
One you probaly are missing is from the card collection quest. 15 cards will get you one. As for the other location I will need o look them up myself.
-Angel Tower
-Eastern Plains
-On the farm inside a building
-Distorted Dungeon in the northern plains
How do I start the card collection? The Angel NPC who wanted to explain it to me never appeared after the mission. Also are any of these chests accessible? The blue one in Distorted Dungeon could contain the ancient tablet.
The farm had still this chest:
And that chest:
Angel Tower has this chest:
Eastern Plains = Frozen Tundra?
Also, are the last two pieces from the shattered world fragment available?
