Well I thought I'd have a go.. See what they are like - Heres my report!
Digging the chest
There is the map, It's called a 'Diabolically Drawn Map'.
I had no barding or a greater dragon so the potential monsters worried me alot! However this is what I got on digging it up.
Two Titans, A Poison Elemental and a Cold Drake (Blue Drake Artwork).
With Two EVs they took out the Poison Ele and one Titan, I dragged the second Titan away and killed that with another EV. I then went in to the alone Cold Drake expecting the worse, However.. It wasn't tough at all, Two EVs managed it without getting hurt at all.
No hardship lock picking the chest (compared to a Level 6.)
Loot:
35k Gold
1 Minor Artifact (Same as Level 6 Map)
Level 7 Map
15 Minutes Alacrity Scroll for Fishing
Tasty Treat
7 Essences
Recipe Scroll
Runed Sash of Warding
Master Skeleton Key
80 Magical Jewellery/Armour/Weapons etc
Didn't find anything special on any of the guardians.
Overall I'm interested in the new drake, Seeing what else there is and if they are harder. I suspect I was very lucky, As I've had tougher Level 6's than that! But very pleased.
