This is a Skyblock survival map with added Shimmer. You only start with a chest with one Jungle seed and that's it! It is highly recommended to play as a Mediumcore player in order to progress unless playing in Journey mode. It is possible to progress as a Classic Character but it is extremally grindy at the start. There is a Demon Alter 377 blocks straight down. The "Dungeon" is 1,297 blocks to the east and the Lihzahrd Alter is 764 blocks west and 369 blocks down. Good luck!
Tips:
Simply throw your copper items into the shimmer and collect the copper ore and wood. Jump off and die to reset your tools and repeat. You can turn the ore and wood into stone and dirt as well
Making housing out of stone is faster than gathering wood
Once you have a house and 50 silver coins, you can buy anvils from the Merchant for iron equipment
Make an iron bucket and head down to the Underworld to gather lava from Lava Slimes and turn that into a bucket of water to unlock fishing as well as making a Jungle with those seeds
Once you defeat the Eye of Cthulhu you can buy Grass seeds and acorns from the Dryad
Turn potions into bottles and then into sand. You can make a Sandgun from turning mining potions into ingredients for Antlion Mandibles and getting topaz from Gem Bunnies or Squirrels
To get the Angler you will need at least 3 sandblocks in a 1x3 pattern and just a little bit of water for him to spawn
