In Realm Grinder, Buildings produce coins and represent the base income. Since v2.1, they visually level up as you purchase more buildings.

Universal Buildings

Farms, Inns, Blacksmiths, and Hall of Legends are considered universal buildings. They are all available by default except for the Hall of Legends which only shows up along aligned buildings.

Important: These four buildings are considered "Neutral" for alignment-targeting upgrades and spells.

Aligned Buildings

Aligned buildings only appear after the player has purchased one of the three Proofs:

In the game, aligned buildings are represented in different colors and easily recognizable. (Good in blue, Evil in red and Neutral in a dark grey)

2 Inn 125 6
3 Blacksmith 600 20

11 Hall of Legends 200 B 250,000 per Trophy

Underlined buildings can be upgraded to Unique Buildings. - Hover over their names to get more information.

Cost & Production

As visible in the above table, regardless of alignment, each building tier has the same cost and production bonus as other buildings in the same tier, and equivalent building upgrades.

Cost of buying next building increase based on amount of building of that type.

Pre Ascension 
Post Ascension 

Building Assistants

Acquiring the first two building tier upgrades of any building type, except for the Hall of Legends, gives one assistant. The first two tier upgrades appear at the 5th and 25th buildings, and buying all of them should give a total of 20 assistants.

Faction Buildings

Buildings that are only visible in the background when you join a specific faction. Since v2.1, they visually level up as you purchase more buildings.

Unique Buildings

At certain reincarnation levels, each Faction will have the possibility to upgrade one building in to a unique faction-exclusive building. (eg. Fairies will be able to upgrade Farms to Enchanted Fields.) These Unique Buildings will grant access to the Research progress system.

R16 is required for Vanilla Unique buildings, R22 for Neutral, R28 for Prestige, R46 for Dragons, and R75 for Mercenaries, each giving access to their respective Vanilla, Neutral, Prestige, and Mercenary Researches.
