Triggering Help Needed

[yeohxin]

Hey guy, I was working on some sort of bossfight map and would needed a spell that require higher level of triggering skills that I have. So I was thinking that could someone help me on this.

List:
1) I needed a poison type spell that deals 75 damage and reduce healing taken by 50% for 5 seconds. Could anyone teach me how to do the "reduce healing taken" part?

2) Same spell but how to make it Bounce off to another target when the current affected target's Hp goes below/above 15%/90% ? How to detect it?

That's all. Perhaps anyone can make a test map that will be the best as I can learns much from it but an example trigger posted will be just fine for me as well. I'll be really grateful for the help.=)

1. You must detect whenever the buffed unit is healed, if yes then damage the unit by half of the heal
2. Use one of the chain template in spell section, and you could add the condition less than for below, or, greater than for above
