After back at Oldak's laboratory, you will enter a dialog about ways to grow your new Dramen Tree. I don't understand how we're supposed to grow a tree underground. Not to worry, the tree grew underground also, you understand. We only need a fertile and bewitching patch. How do we get this? Well, I am no gardner, however I had a conversation with RS gold somebody...
Hmmm, possibly a 5 to 10 ratio, with 5 parts excretory compound enhanced together with the energies native of fairies, and 10 parts common advanced fertilization product improved with a pure form of fundamental magic. WHAT?! Hm? Oh, if you want a less scientific description, 10 buckets of super 5 and compost buckets of camel... waste. Oh, ok. Wait, that is not all. The super compost ought to be fortified with rune character, pure essence to be precise. The camel dung should be combined with pure character charged with energy that's linked to this Dramen Tree.
Ok, you need to get 10 buckets of super compost, and then use a hammer on 10 pure character, then grind each up with a pestle and mortar and add them to the super compost. Do the same with 5 cosmic runes, and insert them of camel dung. Take these to Oldak, and utilize these on the Farming patch next door. Plant the Dramen Seed. Talk to Oldak and he will suggest that while you wait, you gather as much information on whatever is holding Zanik. He could think of two places to find out about Bandos: the Goblin Temple, along with the ogres.
Catch some Goblin Transmogrification Potion (recall, produced from toadflax and pharmakos berries that you receive from the makeover mage), various dyes, and a few goblin mails, yes even the white one that is a pain to get. Input each room and search the Cheap RuneScape gold shelves for a publication. You can't get any of these books in a POH bookshelf, you need to return to the temple.
