Port spells are pretty weird actually.. Check this thread out:

and the description in dbstr is only necessary when you right click a spell and want text for it.. Like when you right click minor heal and it says "heals for between x and x amount of health"
the spell will completely work even if you set the description to 0.. there will just be nothing when you right click it unless you're running MQ2.
