Watching and reading people coments give me an idea for new enemies.
A lot of gathering can be boring for some people it will be good if there is a chance for resorces to becom an enemy fo example:
-Trees can become Treants, that after defiting it you have more wood and there can be a chance for special magic wood (for making wands or cane)
-Ores can become a golem that give more ores and special golem core (for making cane or for magic wepons) .
-digging spots can have some kind of animal thats live underground (like: mole or earthworm) thats give more clay or roots stuffs.
