Don't know why it chose to add that character there.
well, single % is illegal in DESC unless it's followed by a number.
Your DESC should have been DESC:%1|BattlemagicTime
Single % is (I think) ASSUMED to be a 'real' pecent (like: '50% concealment') which has to be escaped (by adding a second %) to be valid.
Ah, yes. The number is in the wrong place. Good catch.
