1.3.5 Patch Notes:

Additions:
- A new Post-Prismatter power generation multiblock, the Chromatic Plasma Refractor consumes cycling colours of Chroma and Liquid D-T Fuel to produce an incredible 20MRF/tick. Associated quests for this multiblock can be found in the "Coalescence" questline beside the Prismatic Alchemy Alloyer quest.

Quest Changes:
- Sky Stone quest in "Building an Arsenal" has extra text about disabling AE2 channels
- Fixed MLEM quest text about overcharged rubies and sapphires
- Large Combustion Engine quest has information about cooling the heat vents on the multiblock
- Ember Crystal quest in "Building an Arsenal" has information about setting up an ember bore
- The low covalence dust quest in "Building an Arsenal" rewards an empty Akashic Tome and various quests along this quest page grant guidebooks for the various mods in use
- Quests involving Prismatic multiblocks in "Coalescence" now look for all blocks needed to build the multiblock

Small Changes:
- AE2 Storage Bus has a tooltip about crashes when interacting with MBD2 capabilities
- The recipe for yellorium ingots has been removed, all recipes using yellorium can be made using mekanism uranium and the associated quest in "Building an Arsenal" has been removed. Yellorium ingots, blocks and nuggets can be converted back into uranium in a crafting table and the anglesite recipe now uses cthonic gold instead of yellorium ingots
- Warp flux drop rate from endermen buffed from 30% -> 80%
- Ender pearls stack to 64
- Thermal Extra component assembly machine has a tooltip stating that ingredients in recipes must be in the same slots as shown in EMI for the recipe to run
- Resprited Polydense Plating
- Squashed many recipes for duplicate ingots, plates and dusts
- Building gadget recipes have been adjusted to place them earlier in progression, namely diamonds have been replaced with medium covalence dust and emeralds have been replaced with gold ingots

Fixes:
- Blood Forge multiblock uses accented demon stone tiles instead of demon alternators in its structure, accented demon stone tiles spawn within the demon realm
- Overworld, nether and end cakes cannot be crafted
- Creative Tank Construction augment has a recipe now

Added Mods:
- Akashic Tome
- Dank Storage
- Building Gadgets
