Not too sure if this one is intended, but quite often, frosty weavers deal no damage when displaying their animations. To replicate:

1 - Open the map editor.

2 - Place a frosty weaver (a frost weaver probably works as well).

3 - Place a bombard or ordinary unit (This Must be an enemy of the frosty weaver so that they fight).

4 - Playtest.

What should occur is that the frosty weaver shall often 'slam down' on its opponent and deal no damage. Sometimes it takes two slams for any damage to occur, other times three.

No output log again as this is easy to replicate.
