The 2nd time you go in, from the save game circle, enter the area where the blast-ended skrewt was. Watch out for mosps! If you put one of the small rocks on the hole in the middle of the area the mosps will stop coming out. When you go up the stairs you should see a vine with Herbivicus flowers, put the big block on the top of the stairs and climb on top of it. Herbivicus all of the flowers and follow them to a small room and you will find a shield.
The 2nd time you go in, starting from the save game circle, enter the area where the skrewt used to be. There should be a big block that you can move using Wingardium Leviosa, behind it is a room. There is 1 shield in the middle of the lake. But, again, beware of the mosps!
The 2nd time you go in, starting from the save game circle, if you go into the area where the skrewt was and go all the way up the stairs you’ll come out on the top of the green houses. If you keep going strait you’ll find a drawbridge, pull it down and turn to the left. There should be another shield. There is another drawbridge, pull it down and there will be a series of bridges that are like a maze, and if you follow them they will lead to a finale drawbridge, after pulling it down you will have to go back through part of the maze and it will lead you to a shield.
The 2nd time you go in, starting from the save game circle, go up the stairs. Turn at your first right and from there go straight. Cast Herbivicus to grow the plants. Bust the statue with the cauldron and there is a shield. Pull the other fence and go down the stairs into a garden. In the garden there is a shield, a dragon statue, and a shovel. The shield and the dragon statue are hidden in the northeast corner behind mushrooms. The shovel is on the left by a pot when you first enter the garden.
Remember to jinx pots, wheelbarrows, or anything that might have beans.
Watch out for vampyr mosps! They always travel in swarms. Remember that using herbivicus on a large flower will attract them for a short time.
