How to speed up researching

How to increase researching speed buff

Increasing the research speed buff can reduce the research time in advance.

You can check how many buffs you have in your “Research Speed” in the “Administration” category of the Monarch Detail screen.

Research – “Typography (max +70%)” and “Super Typography (max +100%)” in the “Advancement” category of the Academy should be advanced.

Monarch Gear – Equip the “Intellect Crown” before starting research (see this article for details). For more information on how to quickly raise the level of monarch gear, please click here.

Duty Officer – Set a duty officer at the Academy before starting (see this article for more details). Any general can be a duty officer, but the ideal is Eulji Mundeok or Hammurabi. They have skills and specialties related to research. See this article for how strong they need to be.

IMPORTANT – Setting a duty officer of a Military Academy also increases the speed of research. (The Military Academy can be unlocked at Keep level 36 and above.) Don’t forget to do this too.

Civilization Treasure – Equip the “Code of Hammurabi” before starting research. (Civilization Treasure Guide)

Subordinate City – Having an American subordinate city increases your research speed. (List of buffs)

Alliance Science – A buff that is activated simply by belonging to an alliance. Donations and raising the level will give you more buffs.

Other things can also make you faster, such as Victory Column, and Dragon (Celtic Demon), etc.

How to get speed-up items

Speed-up items can be used to speed up the completion of the research being initiated.

The main way to get a lot of speed-up items quickly is to kill a lot of bosses. For other details, see the following article.

How to get Research Stone

A good way to get a lot of Research Stone quickly is to kill a lot of Vikings. However, you cannot earn much by just defeating them solo. It is better to kill as many alliance members’ Vikings in a rally as possible.
Details: Boss Chest & Drop Item List

Others can be produced in Research Factory. However, It’s very expensive and are not recommended except in an emergency. (I’ve put together a detailed article on the production of the Research Stone here)

I’m having trouble finding an academy to raise my keep level.
It seems to be hidden in the clouds……
Is it a glitch or something that prevents me from doing the tutorial?
I’d appreciate any help you could give me.
