Steps for survival mode:

Step one: First, get 264 emeralds, and 20 diamonds.

Step two: Trade with clerics and armorors, buy 10 witton frames, and one portal igniter.

Step Three: Build a portal. and light it.

Step Four: Once your there, you need to find the Blue forest. Cut down a tree and build an advanced workbench (That does nothing yet, but is good to have when updating to a version that has use)

Step Five: Go in a cave, and mine crystal ores. You will need 2 redstone blokcs and 6 dust each to convert them to advanced (Optional, but required to go to glaxis. Not required for other gamplay)

Step 6: Find the quartz flowers, and make them into quartz. Put 3 of either crystal type (Advanced, or basic) in bottom right of the crafting table. Then, arrange 3 quartz to the left, and one top middle. Boom. Laser gun. Beware, the basic ones do less damage, and have limited durability (200 uses) advanced ones have infinite durability, and more damage. Craft laser blasts with 2 crystals.

Step 7 (optional. For builders mostly.) Create a cool decorative lantern for your house by surrounding the blue planks with 4 crystals

The other step 7 (Optional, for explorers mostly.) Find the witton lonely cottage, and chill for a little

The other 7th step (Total completionists only) Find the dark forest. Cut down the dead trees, and put them with advanced power crystals, and make darkened crystals. Go back and buy 10 more frames, and one more igniter. Surround them with darkened crystals to get yoursaelf glaxon frames. Build the portal.

Next, go to 150 -150 and BOOM enough portal blocks for a full portal! got there with STONE TOOLS. (The other way to get there requires 264 emeralds and 20 diamonds. yes i said 264.)
