- Unmodified collapsible rock towers have 500 hp and 3 armor. Standard rocks/debris have 2000 hp/3 armor
- Once toppled, the place where the tower previously stood is permanently unpathable. Standard 2000 hp/3 armor rocks will appear at the green highlighted area indicated prior to the killing of the tower.
- If the rock tower falls on any buildings, it kills those that have 500 or less hp and standard 2000 hp rocks will appear as normal.. so pylons, depots, photon cannons, spines, etc. will all die. If the building in the way has over 500 hp, it subtracts 500 hp from the building and the rocks will not appear. *This uses current hp by the way, so a nexus that has just begun construction would die from the rocks and the rocks would appear, even though a completed nexus or any nexus >500 hp would survive it and the rocks wouldn't appear.
- If the rocks fall on a geyser or minerals, the resources are deleted off the map. They are gone forever, and will still be gone once you destroy the resulting rocks.
- Rocks falling on units just make the units move out of the way (regardless of whether they are attacking something other than the rocks, holding position, or patrolling), however if workers in the fall path are mining gas or minerals, they will be killed. Workers repairing a building or unit will live. Units in bunkers will not be killed, they will just be moved to the side when the bunker dies. Most units that are immobile (burrowed zerg units, burrowed mines) will die. edit: still need to test: units that are fungaled, units in the middle of recall, etc.
- Strangely, if rock towers are set up in a line a la dominoes (edit: OR NEAR EACH OTHER IN ANY FORMATION), they act as though they are one singular unit. If you are shooting only the first one, they all will take that damage and all die at the same time. When they fall they all produce rocks. So, if you were to set them up so that there's a pathable gap inbetween each "domino" but still have them hit each other , then you could have several gaps closeable by killing only 1 of the rocks.
- Blizzard did a stealth-change at some point where if the rocks resulting from rock towers' falling at the same time overlap, one of the rocks will be destroyed (it's hard to determine which one will be destroyed)
Still need to test: how far you have to place rock towers apart to make them not share health. And find out if there is a way to unlink rock towers that are near each other.
