Getting / Using the Round Keys - see the video at at: http://youtu.be/u0dBmaVaYiE which shows the obtaining of the final 2 Round Keys and using themThe first 4 Round Keys (as seen in the previous video http://youtu.be/fb92aatbj9Y and previous article) were all obtained in or around the Abominations Swamp - lair of Medusa and her Twin SisterThe Abominations Swamp is accessed off The Lagoons.The fifth Round Key is also found in The Abominations Swamp but on a previously inaccessable island. You need to Teleport there but where is the Teleporter? And why did you need a fifth Round Key when only 2 Round Keys are needed to start the Round Mission?Two Round Keys unlock the wooden gate on Deep Dungeons that allow you to enter the major amphitheatre mission. You face ledges of Skeleton Crusadors and their dogs in such numbers that seem an impossible fight.This video shows how it can be done but when it is done your reward is four brand new 'tomb keys' and soon after gaining these you discover a new mission, this time ... three Round Locks not two! If you don't have the three Round Keys there and then it could be a problem ever getting back to this location!So best have all five from the get go! It can be done and the teleporter leading to the Fifth Round key is situated in "Dark Woods" which is pretty hard to find, it's not obvious!The Woods themeselves are hidden behind a secret door in Prison Fortress.After picking up the four cube keys in Prison Fortress you come to a Portcullis that has an operating button that jammed long ago, the gate is just jammed SO KICK IT IN!!The door breaks and you find a FOOD STASH! enjoy the feast but beyond that (if you already opened up Blue Stones II)  is a secret door that leads to "Dark Woods"A little down the passsageway is an incessed Statue - you can place any item onto the statue's plinth, as soon as you do, several Secret Doors are triggered, one opposite the statue but ALSO the secret door back down opposite the FOOD STASHGo back and find it, enter "Dark Woods" locate a Round Lock on the ground level, look up 2 levels, you see a second portcullis immediately above, any Round Key inserted now would open both that Portcullis and the one immediately below itYou must work out how to go to the Portculis on the next level up. Once there (pull the lever) move sideways, you drop down one level into a Teleporter that sends you to Abominations Swamp and the 5th key With all 5 keys now go to the first two Round Locks that you saw in "Deep Dungeons" they are near to the Up Ladders that get you to Blue Stones I (via Castle Grounds) Once inside the amphitheatre a nearby sign tells you to 'count 90 enemies' but before that occurs (within 5 minutes) you will see the fencing around the up ladder slide upAs soon as possible climb the up ladder, turn right and move forward to access the upper ledges using whatever potions/ bombs/ protection that you can muster NOTE at this point the entry door has probably closed - meaning you are locked in but it could re-open later, always worth checking this!Move up all the ledges and aim for the final Torch Holder that is furthest from you, remove the Torch, an exit route opens for you, move along the empty passageway - this leads to Blue Stones IIn Blue Stones I restore your Team, make your way to Bluestones II where new passageways have now opened up, explore them and find the new Three Round Locks, you have the 3 Round Keys so use them to enter the next amphitheatre, basically the same all over againThis time on the top ledge there are Four Valuable keys, 1 Round Key (that you need for Dark Woods) 2 Gear Keys and an Iron Key!
