My ideas:
Dwarf - add the abilities "Repair" and "Worker":
Repair - Dwarves can repair mechanical creatures, restoring hit points equal to the number of Dwarves.
Worker - Dwarves can work in mines, increasing the productivity of mines, depending on the number of Dwarves and with a certain limit.
Peasant - "Worker" and "Militia":
Militia - in the "Squire Guild" and "Archery Range" buildings, peasants can be trained into these warriors for a certain period. After the period expires, they become peasants again.
Elf - "Taming":
There is a 15% chance that if Elves are attacked by a beast, the beast will not attack (the Elves have tamed it). But the Elves also do not counterattack this beast.
How do these ideas sound?
Многие их ищут, многим они вовсе не нужны, а многие даже не замечают их, не понимают что они вокруг нас, каждый день, везде.
А эти чудеса порой, сокрыты в обычных, привычных предметах.
