Rusty casket

The Rusty casket is a quest item found by the player during the Horror from the Deep quest after killing the Dagannoth Mother.

After completing the aforementioned quest, players can take this to Jossik on the 1st floor of the lighthouse (2nd floor for America) and he will tell them something is written on it. Depending on which answer they give, he will give them a damaged prayer book in one of three colours, which correspond to the three major gods of Gielinor. The pages for these books can be received from all three levels of Treasure Trails.

Should you lose this book Jossik will give you the old book back. Please note: All pages previosuly put in these books will still be there.

If you do not like the book you chose or want more than one you can buy any of the other two off Jossik for 5k. You can then fill up the other two books with pages. Below is some stats to help you make you choice.

Zamarok: Very exspensife to fill compared to the others (over 1 mil). Gives +8 in all attack stats

Saradomin: The 2nd most exspensife to fill but much cheeper than Zamorak (about 200k). Gives +8 in all stats and +5 prayer bonus.

Guthix: Cheepest to fill (around 100k). It gives +4 in all defence and attackk bonuses.
