Sinatuki Quest/Spoiler

Requirements

 * Access to Nibelor (complete the Barbarian Test Quest and The Ice Islands Quest, up to Nibelor 5: Cure the Dogs).

Method
You will need to give a combined total of 99 Green Perches and Rainbow Trouts to Sinatuki and after that give her one more Green Perch or Rainbow Trout (100 fishes in total). There are multiple ways to obtain the fish:
 * Ice Fishing in and around Svargrond.
 * Loot them from Chakoyas or other creatures.
 * Buy from other players.

After obtaining the required amount of fish, go to Sinatuki and talk to him/her. After delivering all fish you will get your reward of 5 Shards and the achievement Jamjam.

Transcripts

 * Sinatuki will take the first stack of fishes the player have (green perches or rainbow trouts)


 * Sinatuki will take the last stack of those fishes (green perches or rainbow trouts) from player's inventory. If you have 100 fishes, you must take one away from your inventory, or else you will have to deliver another fish, because the NPC eats the entire stack.
