Tricks and Glitches

Infinite Money Glitch (Old versions only)

If a worker is in range to place a structure, but it cannot path to place that structure, it will place it anyway but refund the resources. These videos: https://www.youtube.com/watch?v=rmrgi0N7HX0, https://youtu.be/kWsgPMd3Zmg

No Item Cooldown Glitch (Old versions only)

In old versions of WC3, if you transfer items between heroes they lose their cooldown, and if you target an item somewhere, and then move another item into the slot of the item you are targeting with, you will use the item in the slot that you originally targetted . I haven't tested the following, but according to patch notes it also works if you just drop and pick up or sell and buy items.

Displacement Glitches

One thing to note: At least in new versions of Wc3 (idk about old ones), displacement glitches do not allow you to go up or down cliffs (not even if there is a ramp connecting them).

Displacement Glitches occur when the collision radii of two units are on top of each other. The unit that next has a pathing update (caused by the stop command, the move command, or just continuing to move), it will find the closest free place to put it within a certain radius and put it there.

Using a worker (or hero with tiny building) to build a building on top of itself will cause the worker or hero to be displaced.

Summoning units causes displacement.

Mirror Image causes displacement

Unit creation causes displacement (through triggers or normal spawn). Note that in normal spawn, the unit will appear at whichever corner of the building is closest to the rally point. Unit creation displacement from building is centred on the building and not the spawn point.

In old versions of Warcraft 3, workers turn off pathing when instructed to gather lumber. This allows for displacement glitches. Ordering the worker to do something else will displace the worker, and alternatively when the worker reaches a tree it turns pathing on, meaning that the next time a unit underneath the worker has a pathing update, it will be displaced. In new versions, worker pathing is a very tricky thing indeed.

Healing ward glitch

Healing wards can be sort of "displaced" but not really displaced. This can grant vision. It's sort of weird how it works, I haven't looked into it. Watch this video: https://www.youtube.com/watch?v=jrn5M-yytdk

Illidan Silence glitch

If Illidan is Silenced while channelling to close a dimensional gate (or indeed probably anyone is silenced while channeling any spell), he will stop channelling. Watch this video: https://www.youtube.com/watch?v=1RRRDMOHDy4
