In addition, the calculated FP to block the first place and the total construction costs of the Great Building by the owner.

Table and chart of construction cost and rewards of Great Building The Arc from Forge of Empires game including The Arc bonus. With such investors, upgrading The Arc from level 1 to level 80 costs 24,105 Forge Points by the owner. Five friendly investors throwing in thanks to the extended The Arc for a 190% return strongly reduces the required own contribution. This allows You to earn by investing less PR than the return or strongly accelerate the construction of Your own Great Buildings by mutual, jointly investing more PR in your pearls with your friends.

Would be nice if the devs (or someone) could answer what happens with increase on GB boni past level 180 for arc or in general. I've seen arc level 184 still stuck at 100 which I'd blame on floating point precision but really I'm not sure. The Arc at level 80 gives a 90% bonus to earned Forge Points, Great Buildings blueprints and medals from rewards for investing in other players' Great Buildings. 1 I've come to wonder wether the arc does give a 0.01 increase (or more) or non at all past level 180. Its expansion to level 80 greatly accelerates the development of the city and other Great Buildings. The Arc is one of the best Great Buildings in Forge of Empires game.
