Armoury

Prerequisites: Main Building level 3, Academy level 1, Travian Version 2.5 or higher

In the armoury's melting furnaces your warriors' armour is enhanced. By increasing its level you can order the fabrication of even better armour.

An upgrade done to a unit counts for all units of that type in the village the upgrade is done. This means an upgrade done in village A does not count for troops coming from village B.

NOTE: A units armour value ONLY helps when defending.

The bonus added by upgrading a unit is estimated to be 1.5% (factor 1.015). This means a unit's defense worth is base_worth*1.015^armoury_level.
The Gallic Phalanx for example has 40 defense versus infantry and 50 defense versus cavalry by default. By upgrading the Phalanx armour in the armoury you get these results:

Armoury upgrade level
0	40	50
1	40.6 (40*1.015^1)	50.75 (50*1.015^1)
2	41.2 (40*1.015^2)	51.5 (50*1.015^2)
x	? (40*1.015^x)	? (50*1.015^x)

With this Development calculator you can calculate how long each upgrade will take in the armoury and the blacksmith.
