I am not stupid.
I am not going to face those worms at all, much less follow them back into their territories, where I would be vulnerable in every way.
Going into the enemy's territory is a stupid move in general. In the case of the underground monsters, it would be far worse than just being stupid. It would be on a whole new level.
Entering those tunnels means death for sure.
Unlike while fighting above the ground, where the landscape wouldn't be so congested and restrain our moves, it would be totally different in those tunnels.
No dangerous moves can't be executed as that could bring the stability of the tunnel and would collapse, leading you to be buried alive. If you are powerful enough or not injured by that fiasco, there is a small chance of escaping but those chances are low.
