Well, i love making huge mines in Stonehearth but i think that just digging in the rock is too easy and boring.
So i think that adding those things would be cool for an underground adventure :
1- Caves to explore with chests, monsters and rare ore like gold.
2- Goblin tunnels with wooden structures,chests and lot of goblins that will get out of their tunnels to steal your goods and attack your settlement.
3- Lava can be found on deep mines with some kind of fire monsters and dragons. (Maybe in the Lavasmith update).
That’s all but i hope something like that will appear in the game later to change a boring mine into an awesome adventurous gameplay
But how should this titan be killed? and do you think that there should be a special way to kill a titan (like a specific spell or ritual performed to kill it?
They just have to add more magic things to the game that would make the world so much more alive.
