Fast answer
The answer before the background
Tower Dominion Discovery increases access to neutral-building opportunities, while the Codex records information and unlock knowledge across play. Doctrines modify and specialize a run. The Charge System is not a universal resource meter: it is a specific building whose adjacency can increase the Experimental Pulse Emitter's rate of fire.
Definitions
Separate four systems that are often mixed together
| System | What it does | What it does not do |
|---|---|---|
| Discovery | Raises the chance of finding neutral-building opportunities according to the community reference. | It does not directly rank every tower. |
| Codex | Records unlocked knowledge and reference information. | Opening the Codex is not itself a combat buff. |
| Doctrines | Apply reinforcement and specialization modifiers during progression. | A doctrine is not automatically useful without a matching build. |
| Charge System | A building that supports the Experimental Pulse Emitter through adjacency. | It is not a global energy mechanic used by all factions. |
Decision rule
Choose Discovery and doctrines around the board you have
- Take Discovery when neutral-building access can improve the current route or economy.
- Do not sacrifice wave survival for a future option that may not appear in time.
- Prefer doctrine effects that strengthen placed buildings and the current enemy matchup.
- Use the Codex to verify names and interactions, then test patch-sensitive numbers in the live build.
- Place a Charge System only when its supported Pulse Emitter and adjacency space justify the opportunity cost.
Evidence
How to answer a mechanic question without repeating a stale wiki line
Start with the current tooltip and patch number. Use the Codex and official update notes for changes, then compare the community mechanics page. If a number differs, record both the test conditions and the version instead of forcing one timeless answer.
This page deliberately explains relationships rather than publishing an unsupported best-doctrine list. A useful ranking needs faction, mode, patch, and an original comparison dataset.
FAQ
Common questions
What does Discovery do in Tower Dominion?
The community buildings reference says Discovery improves the chance of finding neutral buildings. Confirm the live tooltip because exact behavior can change.
What is the Codex for?
It is the game's reference and unlock record. Use it to track knowledge and inspect current entries rather than treating it as a direct combat upgrade.
What are doctrines?
Doctrines are progression choices that modify reinforcements or specialize buildings and strategy during a run.
Is Charge a global resource?
No. The Charge System documented by the community wiki is a building interaction associated with the Experimental Pulse Emitter.
