An standing stone draws the curiosity of adventurers passing through... Right into a deadly snare.
Though not obvious at first, Connor Johnston designed this as an encounter map specifically for their 9x9 Sinister Spider encounter assets!
In-fact, each Sinister Woodland map variant comes with a version showing an open trapdoor and reaching silvery webs; a version which you can switch to as soon as your spider is ready to spring its trap!

The map itself is 44x32 and offers plenty of space to maneuver for a 9x9 spider and its wily prey. That said, the base maps are also wonderful on their own, sans-trapdoor and sans-webs! Perhaps it is just a standing stone in the woods after all.
I'm curious to know what sort of features you would add to such an encounter, so please share your ideas below. :)
