Death and Decay Building Reduction

I've been having a problem with Death and Decay's building reduction... Basically, I want to have Death and Decay do 8% damage vs. ground units while only doing 1.6% damage to buildings.

With this in mind, I thought that it would be logical to set Max Life Drained per Second (%) to .08 (default .04), and Building Reduction to .20 (default: 1.00) [.08 x .2 = .016]. However, changing the Building Reduction did absolutely nothing in the way of making the damage less to buildings. If someone could tell me what's up with this, I'd appreciate it a lot...


For further reference I found this thread: http://www.wc3campaigns.com/showthread.php?t=29531
but it didn't have an answer, as far as I could tell at least.

It probably isn't possible. Not all spells use the fields that they have.

The only way then would be to trigger the entire thing (i.e. constantly pick all units in the affected area and apply damage).

An easier way of triggering it would be to have two D&Ds, one that cannot target structures, and one that can only target structures. Then, give one to the hero, and when he casts it, use a dummy unit to cast the other one at the same spot. You'll also need to store that unit to a variable so you can remove it if the hero stops casting prematurely.

Thanks a lot guys.... those are both good alternative options, since the building reduction evidently won't help much... Now just to figure out which suggestion to use.... they're both pretty good and not too hard to do... hmmmm....

Thanks...
