Research Tower

We need more troops! It has been suggested that this page, or a section of it, be extended. Once the points are expanded, any user may remove this tag.

The research tower gives the player access to research things by paying Resources, which provides a wide range of benefits. Some research projects need resources or rubies.

Here are some of the screenshots and features of the Research Tower.
This is the approximate cost of researches.

Building upgrade Edit

Costs are without a Master builder.

Level	Wood	Stone	Time	Required experience level	Research speed	Unlocks
1	?	?	10m	6	100%	Core research (tier 1). Craftsmanship
2	13803	23546	35h	39	100%	Advanced research (tier 2). Maneuver + Steel tires

4	74281	80534	~44h	70	140%	Veteran longbowman + Veteran halberdier

Researches Edit

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.

• With level 4, the veteran version of the Two-handed swords, Halberdiers, Heavy Crossbowmen and Longbowmen will be unlocked.
• These research options can be executed with resources and do not require the Event-Researcher.

Strength-wise, these new veterans are in between the standard variants and the Kingsguard units.

Build itemsEdit

Main article here

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.
