It's all in the cards!
Henzell says...
Level 5 Ice/Hex. Attempts to slow all non-rC+ monsters in sight. The duration of the slowing is based on power and reduced by monster HD (and unaffected by Will). Slows each target for 3d(pow)/6 - random2(HD) turns. Cold-blooded monsters are slowed for twice as long.

Information based on master branch and the great LearnDB.
