The Research Tower gives the player access to research, which provides a wide range of benefits. Most research projects require resources, but some cost kingdom resources, coins or rubies. Since April 2022 update, the research tower level in mobile version is now same as PC version. It also unlocks core technologies which is used for lower levels, and leveling up Veteran and Relic Units.

Listed by section going from the right side of the in-game charts. Time is listed in the format hh:mm:ss (hours:minutes:seconds with leading zero; always 2 digits). Time is at its level speed, meaning a tower level 3 research is at 120% instead of at unnatural 100% and no further reductions (eg. Thirst for knowledge or Genius) - unless otherwise noted.
Note: If a time duration is marked with a tilde (~) character, then it means unsure. Please correct/confirm it.

Build items are craftable items that are used to enhance a building's productivity or alter its appearance. They are crafted in the Construction Yard, using build materials. They can also be found by purchasing them from event stores and Special offers, and placing high in rankings for events.
An update allowed the research of build items at higher levels. Relic build items, the superior version of normal build items, require millions of coins to research.
Blueprints[]
There are six categories of blueprints: Battlefield, Troops and Tools, Trade and Storage, Production, Military, and Economy. They can be unlocked for research once the player upgraded the Research Tower to level 3. Researching these can guarantee to either expand more levels for a certain blueprint or provide access to build one.
