A divine snare that lashes from an ancient ruin's shadow, seizes the first creature to disturb its ward, and squeezes at the creature's body and soul. Its grip is painful but survivable, though rep...

The corpse of one of Sir Wilhelm's knights is caught between death and undeath. Necromantic void energy tries to remake the body, while the knight's ghost fights it in agony. When living creatures ...
This concealed street mechanism turns a routine crossing into a sudden arrest. A pressure plate releases a ratcheted chain that whips around the bollard and snaps taut across the lane, sweeping fee...
This tamper-resistant alarm lantern is disguised as ordinary street furniture. When someone crosses the service arch, a hidden plate releases a spring-loaded shutter. The lantern flashes a painfull...
The square's old fee post is more than a place to pay market dues. Its buried winches haul hooked chains through the cobbles, catching the ankles of anyone who crosses without paying. During a figh...
This rigged supply cache is designed to punish anyone who rushes in to seize provisions. A decoy crate releases a cargo net, while the winch reels a weighted pack line across the battlefield. The t...

The Bastion Siphon is the heart of Vhaelon's battlefield advantage: a hungry arcane engine that draws vitality from nearby combatants and routes it through the fortress. It does not merely injure t...

This defensive array was designed to protect a vital conduit by turning its own energy into a weapon. In the encounter Stop Zaricia from breaking the conduit, it makes the battlefield a contest for...
