FR: Shatter creates permenant shafts

[Laraso]

Make shatter destroy floor tiles, leaving a permanent shaft trap in its place that has a 100% chance to suck in anything that walks over it. This can happen under any normal floor tile including the tile the player or enemy is standing on.

[HardboiledGargoyle]

the main objection i can think of is that it will make it hard and annoying to shatterkill monsters on floors where shafts can form, and overpopulate bottom floors

[Laraso]

The game already teases you by destroying nearby walls. I wont be satisfied until every tile in the dungeon is an empty void
Think about how fun it would be to fall from D:1 all the way to Zot:5
