Changelog
Spectrum 1.10.0 for MC 1.21.1
The Deeper Down got quite a bit more populated!
The Marrow
- A slow, but sturdy Skeleton variant made from Dragonbone.
- In addition to their innate Toughness and increased heath, they shoot Potions of Stiffness, making it even harder to strike them down
- They replace the vanilla Skeletons in Dragonrot Swamps
- They Drop: Arrows, Stiffness Tipped Arrows & Dragonbone Chunks.
- Texture by Mr. QuickStrike!
The Splinterspawn
- A small, observant and shy Silverfish variant
- They don't attack and rather flee, trying to hide as fast as possible. Actually, even getting them to leave their block will be a bit tricky
- You will rarely find Splinterspawn infested blocks in the Razor Edge. You ever think you are hallucinating, no, that might only have been a Splinterspawn eyeing you
- Breaking their block with Silk Touch will make it vanish, you can drop the block including the mob using Resonance, while Pest Control will earn you a nice sum of XP instead
Redstone Sand rework
Redstone Sand has been completely revamped. It has lots of utility now, useful in many redstony scenarios.
- transfers redstone signals in any direction, including upwards and downwards (with is kind of a pain in vanilla)
- immediately gives off power to neighboring Redstone, but transferring to other Redstone Sand creates a slowly growing signal
- Stores energy. Signals drop off slowly after turning off the input
- Will fall when powered and not supported
- Retains its energy during the fall, giving a short Redstone Pulse when landing
Improvements
- Rewrote quite a few guidebook entries
- When using a Crafting Tablet in a Pedestal, hoppers and other item transport methods now only fill each slot as needed, instead up to 64 items, making autocrafting setups much more quick and efficient
- You can bonk Item Roundels with the Paintbrush to make it spin the other way around (a godsend, if you enjoy mirrored setups)
- The Guidebook now has a way of listing Item => Ink conversions. The guidebook now also shows that you can use Dye, in addition to Pigment
- The Radiance Staff now supports Efficiency. Its floodlight ability places lights a lot quicker

- The Primordial Fire sound is not only 60% as loud
- Updated all Fluid Collision recipes in EMI
- Renamed the 'craft_colored_sapling' advancements title. Now called 'Botanian Rhapsody'
- Lowered the crafting time of the Soothing Bouquet. The required time was longer than midnight even lasted - making it unable to be crafted unless using speed upgrades

- Kindlings are now immune to Primordial Fire
- The Creative Menu now has a full Bottomless Bundle for testing shenanigans
- The soothing bouquet recipe now mentions its midnight requirement

- Added an advancement for placing down a Forgotten Memory
- Added an advancement for trying to create a Spawner of a blacklisted/boss/unknown mob
- Added raw Azurite, Malachite & Bloodstone blocks. The Azurite one causes Azure aura, as with all Azurite blocks
- Redesigned the Wireless Redstone puzzle structure so players that crouch into the water flow can't get stuck anymore
- Nightdew Vines now use a proper loot table for their rare drops. Added loot condition matching nearby sleeping entities
- The Block Breaker now uses Fabrics Fake Player API - making it drop cloaked drops even if their owner is offline
- The 'open DD portal' advancement now also procs when creating it via Bottling up Ruin

- Improved inventory handling across all containers. Crafting Chest now start autocrafting as soon as possible. They did not run if you added more stuff to an existing stack before
