[TheTurnipKing]

Is it just me, or is such a curse a bit strange for a strategy game? I mean, its effects are extremely vague mechanically, and if there is something table-top strategy games have it is precise mechanics...

The spells terminology would probably be a tad less loose in a tabletop version of the game - something like allowing the other player to overrule an attack for 1d3(s) turns or something, with the random element giving the spell a not-entirely-predicable duration.

And if it's a video game, the rule would probably be quite a bit more involved mathetically, (taking into account chances of other warlords in the stack influencing the afflicted) since that's what video-games do best.
