Perhaps you're like me--confused as to just what adventuring (for Kingdoms) or domination (for Empires) techs are needed to raise notable, quest or NPC/champion levels. Well, fret no further!
<< KINGDOM ADVENTURE TECHS >>
Kingdoms have three primary adventure "tracks" within the adventure tech tree; exploration, quest and recruiting. Each track is listed below along with a brief summary of the type of techs you can expect to find within. Rarity, presumably as a percentage, appears in parenthesis after the name of each tech in the track.
Exploration Track
The exploration track reveals a variety of resources, and to a lesser extent "goodies." Techs in this line do not increase notables or quest levels!
Exploration (100) --> Lost Bounty (100) --> Lost Maps (100) --> Rare Resources (100) --> Secrets of the Nemesis (100)
Quest Track
The quest track contains techs increasing either quest or notables levels. Ruin delving, as a special case, increases both. This track also contains the potentially game-winning "Quest of Mastery" tech.
Quests (100) --> Ancient Lore (100) --> Ruin Delving (100) --> Ereog's Journals (100) --> Dungeoneering (100) --> Breon's Letters (75) --> Quest of Mastery (20)
Recruiting Track
The recruiting track increases the number and strength of NPCs on the world map. Naturally, these are NPCs that may be recruited by players as champions, for a fee. Refined charm may be researched to lower the hiring fee.
Recruiting (100) --> Heroes (100) --> Legends (25) --> Refined Charm (20)

<< EMPIRE DOMINATION TECHS >>
Empires have two primary tracks within the domination tech tree, one of which is branching. Both tracks are listed below along with a brief summary of the type of techs you can expect to find within. Rarity, presumably as a percentage, appears in parenthesis after the name of each tech in the track
Codex Track
The codex track increases the number and strength of NPCs on the world map. Naturally, these are NPCs that may be recruited by players as champions, for a fee. Refined charm may be researched to lower the hiring fee.
Morrigan's Notes (100) --> Umber's Diary (60) --> Curgen's Journal (60) --> Legend of the Bane (80) --> Kir Tion's Codex (80) --> Refined Charm (20)
Mapping Track
The mapping track contains techs increasing quest or notables levels, often both at once. This is the only track, for both Empire and Kingdom civilizations, featuring a branching tree. It also contains the potentially game-winning "Quest of Mastery" tech.
--> Destiny's Scrolls (50) --> Treasure Hunting (50)
Mapping (80)
--> Myth Making (60) --> Plundering (50) --> Demon Lairs (50) --> Quest of Mastery (20)

Treasure Hunting: Raises quest (Q3|4) level. Raises notables (N3|4) level.
Umber's Diary: Reveals gold resources.
Additional Notes
Either the Empire or Kingdom's "Refined Charm" tech may not be working as intended--the Empire version could be used to continuously spawn more NPC champions. It is possible, however unlikely appearing, that this is an intentional design feature marking a difference between the competing civilization types and the overall design of their respective trees.
Research within the Empire's domination tech tree is significantly less certain than the Kingdom's adventuring tree. Morrigan's notes is the only tech sporting a 100% chance of appearance. Regardless of rarity, one tech is always assured. Still, the Quest of Mastery may be easier to achieve for Kingdom civilizations because of the direct nature of the quests track.
