Yes, it's a reward from the cooks assistance quest, check the quest log for cooks assistance. "As a reward he now let's me use his high quality range which let's me burn things less whenever I wish to cook there"
I have had a lot of randoms too last days. Mostly while doing "waiting" tasks like fishing though. Not much while fighting. But I'm happy with it. Got my first mime ever yesterday.
Hmm... I remember having seen a topic about this clue... let me see if I can find it. Edit -> I found it http://forum.tip.it/viewtopic.php?t=573 ... ight=swamp
When you go through that cave again anyway you'd better also make a ninja monkey greegree and a zombie monkey greegree. As you need those for RFD. (You need a guard greegree for RFD too, but you already have that one).
I'm lvl 5 defender now. And on 7 runs to the queen as defender I think i've only used the western trap for 2 kills. Almost all runners go past the eastern trap. And by just camping there. You can kill all the runners really fast.
I think the only thing wrong with the defender is that the traps have only 2 uses. And for finding a team. It's pretty easy when you get at a higher lvl. I'm only 89 combat. Yet I can get in 90% of the lvl 100+ teams because I'm a lvl 5 defender.
