ToME: the Tales of Maj'Eyal

Seen on Linux 64bit with version 1.6.4 and 1.6.5.
I don't know if it still exists on 1.6.6 (did not have the right items/skills yet to check), but the changelog said nothing, so:

When I'm on the overworld map, some skills and effects affect the roaming monster groups:

• Cloak of Daggers sometimes hits monster groups next to my character
• Daunting Presence intimadates monster groups nearby

The effects don't seem to really do anything, but the effects pop up in the game view (red zeros for the damage of the cloak or the "intimidated" message).
