Arc Technology

Laser Gun:
When using "Z" it switches to the laser gun, holding down the right click fires a particle beam that does 5 damage, has a range of 16 blocks without going through walls, and has a 4-second cooldown after 10 uses.
Genomic Instability: When hit, it gives the instability effect, doing 2 damage every so often (the time depends on the level of the effect).
Ionized: Similar to the laser gun, it fires a beam, but this one gives the ionized effect, which has similar parameters to instability, but if you have less than 1 heart, you will explode.
New Blocks:
Arc Furnace: It activates if there is lava underneath it. From now on, melting unused boosts will give you Molten Arc Debris. By placing 2 in the arc furnace and throwing a nederite fragment at it (roll 1 at a time), it will be ready. Placing the arc mold next to it will empty it, creating molten arcerite (it will burn you if you touch it). Wait 10 seconds or use a bucket of water on the block to obtain the arcerite, which will now be used to make the arcane sword.
New rooms for the fortress:
Forge: Where you can now find ores, boosts, and minerals.
Tower: Where you will find the Atom Totem for the...
NEW BOSS:
Arc Atom
Summoned by using 4 Arc Cores (obtained by killing wild AIPAs) and pressing the block.
Arc Atom has 4 phases. The first will appear after its health is half gone. It will summon an AIPA from the spawner, which will heal it (while this happens, it will be immune to damage).
In phase 4, it can only be damaged by the arc sword and will also start shooting ionized atoms. Be careful!
Upon death, you will receive one of the new boosts (Genomic Instability or Ionized).
Changes:
Arc Fort chests will no longer be able to drop armor or minerals, only those in the forge and tower.
Sword crafting has been changed, replacing nederite with acerite.
AIPA will be able to spawn wild in the world; they cannot be tamed.
