May be cast at an enemy model within 12". A pit of disgusting slime opens up beneath the target's feet. Roll a D6 - if the target rolls less than his Strength he escapes the pit and it is dispelled. If he fails, he is trapped in it. While trapped, a victim may do nothing at all.
The victim may attempt to escape at the start of each subsequent magic phase - roll less than his Strength on a D6 to struggle free. If he rolls more he is slain. If he rolls equal to his Strength he is still stuck.
Remains in play
Note that a victim can roll to attempt to escape in each magic phase, both his own and that of his enemy.
