Blacksmith

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

In the blacksmith's melting furnaces your warriors' weapons are enhanced. By increasing its level you can order the fabrication of even better weapons.

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: better weapons only raise the unit's attack worth, it makes no difference when defending

The bonus added by upgrading a unit is estimated to be 1.5% (factor 1.015). This means a unit's attack worth is base_worth*1.015^Blacksmith_level. The Roman Imperian for example has a default attack worth of 70. By upgrading the Imperian weapon in the Blacksmith you get these results:

Blacksmith upgrade level
0	70
1	71.1 (70*1.015^1)
2	72.1 (70*1.015^2)
x	? (70*1.015^x)
