Belated response to Grid: If you haven't found it already, the spell list might be what you want - click the 'memorize' button next to 'cast' on the spell tab, it will then automatically cast the spell while you're adventuring. Very useful for buffs and regen spells, since it eliminates the need to remember (and be there) to recast them. Massively expands idle ability. Now if only you could autocast when NOT on an adventure...
An equip item, I think, where did you get it? I want one but haven't been able to find it. Also, does anyone know what the Phrenesis' Healing spells do? They don't have descriptions. Also also, Embolden claims to work on "frightened creatures" but doesn't fix my Nature's Wrath, is that a bug or did I misunderstand what "creatures" means?
LazyDragon, get your Anatomy and Alchemy to 5 each and you'll unlock the ability to make blood gems. Beta, that sometimes happens if you have a negative base rate for the resource in question, so the only way to fix it is to get your base gold rate back up to at least 0. Find what is losing you money and get rid of it, or find a way to earn more money passively.
Andri, check that you have everything needed to purchase it and space for another minion. Unrelated, but has anyone figured out what carried over from the winter event? So far all I've noticed is that I still have the Orb. I *think* the bonuses to various max skill ranks from encounters in the event dungeons were retained as well.
Having collapsible categories was a decent idea, but I can't seem to see my action block anymore. Y'know, the thing that shows all the actions you are currently performing.
Don't forget to Sublimate Lore whenever you are at max Codices, too. If you have the Lexyrinth, I assume you already have upgrades that automatically generate those. You temporarily lose max research, but the gains will never go away. I've gotten up past 100k max research at this point by doing that.
DarkLordArceus, I refer you to 32 posts down the comment thread from your question. Astral Seer requires Astronomy 15 and Planes Lore 15. Eragon, I admit that I've forgotten what unlocks Gate, but do you have any runestones? If not, you might need to get one before you can see items that require them.
Bumburnyak: Try getting a Mineshaft, using the Unearth spell, and simultaneously Mining and doing something else to get money. The Appraiser takes your gems because it simply applies a flat modifier to your gem rate without checking whether you're full on magic gems.
Saalko, do you have Stables? I think you might need that to get a Mule, although I'm not certain. Almighty, if you hover over a spell, hold ctrl, and hit a number key, you will hotkey the spell to that key - just hit the number later to use the spell. You can also restrict spells displayed by element and/or level. Monstrofocozo, Mage Tower is the largest home, but you can expand it with certain upgrades; by the sound of it, you already have Cellar and Basement, but you might not have a Werry (requires a Tier 5 class, a Gate (furniture), and 10+ in Geomancy, Pyromancy, Wind Lore, or Water Lore) yet, which increases space available by 30%. Void Lore (requires Planes Lore 10+ and a Tier 5 class) also increases available space, if you don't have that yet.
