I post my remark here because the bug report button from the game interface seems to have some problems
The gold digger skill announces that gold income will be increased by x%. But it seems to consider only the city income, not the gold mine income
gold mine income too.
Leave your town with your gold digger (go scouting) and youÂ´ll see that your mines produce less. i have a mine producing 19838 gold, thats
14000 base (lvl 7)
4200 imp (30% improved)
1638 digger (9%)
gold digger works fine for me.
p.s. check if you have maintenance cost
p.p.s. one important thing, gold digger comes after imp. its not 14000*1,39, its 14000*1,3*1,09. important considering the question if its worth improving your mines
so my hereo needs to stay in town, to have the digger skill work, right?
and its the same with all other skill like charamatic leader aso
yes most of the skills have a limited aera of effect (one region, one army or one hero...)
