(Coming soon, with Game Update 4.2... which, barring unforeseen circumstances, should be some time next week!)
We're typically not ones to make mountains out of molehills, Keepers. Instead, our wacky Workshop wunderkinds
have come up with this awesome little goodie, known as Dante's Mound!
Initially available for a singular purchase (for the price of 250 Dreadstone) once your Workshop attains Level 8, Dante's Mound is a 1x1 non-consumable Trap that has the ability to launch boulders over walls, hitting targets that are foolish enough to get within 3 tiles, leaving behind a lava pool that deals additional Fire damage (in the form of Damage over Time) to those enemies standing in or crossing through the pool. The Physical damage upon impact is Moderate "splash"/AE damage; the Fire damage, per tick, is relatively Low... unless the enemy in question has a susceptibility to Fire damage.
Strategically, using the proper Door, corridor, and other Trap placement, Dante's Mound has the potential to wreak quite a bit of havoc!
A second Mound is available for purchase at Workshop Level 9, and a third is available at Workshop Level 10. The first tier for each Mound is available for 250 Dreadstone; subsequent upgrades (which increase damage for both bolder and lava pool) will require Stone.
There's a certain natural beauty associated with the glow of lava pools, Keepers... we just advise not getting TOO close. Especially if you're feeling particularly... Trollish.
