Skyblock? Yeah, they've been done before. Everyone and their mother has put one out, right? Probably. Well when Vazkii put out the Garden of Glass add-on for Botania, I thought "hey, that sounds pretty neat!" If nothing else, it was a change of pace from the same vanilla or Ex Nihilo based skyblocks we're all used to by now.
Enter, Magic Glass Garden, a Botania and Garden of Glass based modpack. Thaumcraft for additional awesome, plus some TC add-on mods. A couple of storage mods (but not AE), Extra Utilities for a few useful items and ore processing via the QED, and Tinkers' Construct. Frankly, TiC is pretty unnecessary, but the Witching Gadgets Brain Jerky from the Drying Rack comes in reaaally handy when you can't run around the world, scanning aura nodes for aspect points.
Technically it's an HQM pack, with a handful of quests available. It's not a traditional Quest focused pack though. Primarily HQM guides the player to ore processing, provides some Thaumcraft bonus items, and finally; the Crimson Rites, a sinister node-in-a-jar and an Eldritch Obelisk to allow access to the Outer Lands. Eventually I plan to replace that with a different method, similar to the Ex Aquilo "Portal In A Box".
Skyblock packs are great, we all love them. From the original little vanilla block of dirt, to the fantastic purple-tinged packs of 2014 and 2015, and everything in-between. Mods have been written to allow for different ways of getting resources, and additional mods have come out to expand on those. Now, we have a different direction we can go. From Vazkii, the author of Botania, we have Garden of Glass. This pack is based around Botania & Garden of Glass, plus Thaumcraft, because they're both awesome. In addition to that, we have Extra Utilites for a few utilitarian blocks and items, and Tinkers Construct for tools, cheaper books, drying racks, and better crafting tables. Also Jabba, Iron Chests, Storage Drawers, Ender Storage, Translocators, and Refined Relocation for storage, sorting, and movement of stuff. A handful of Thaumcraft expansion mods for additional awesomness. Progressive Automation, mostly to make tree farming less of a grind. A wrench mod for block orientation. There's a couple client-side and Quality of Life mods, for a touch more sparkle and ease of use. Oh yeah, and HQM. But this isn't a normal questing pack. You're not gated, or required to follow a progression. There's a couple of mob grinding quests, for an alternative way to get a few items. Something to help with ore-processing. And a few necessary Thaumcraft items, once you're ready to explore the Outler Lands. Kind of hard to find Eldritch Obelisks in a void world.
