Note Deathfire Touch does half for AoE and DoT, over half the duration (so same dps). I'm not sure if DT gets proc'd more than once for DoT's, but if it does, then it sounds like you're basically correct in idea except the last tick that triggers it only lasts half the time. Let me see if I understand the math here...

Over the 4 second duration of the shroom, the 1st 3 seconds is 20% AP from DT, and the next 1 second is 20%/3 + final tick 10% = 36.7%. That puts it to a total 50%+36.7% = 86.7%. So 4s poison gets an extra 16.7% AP over a single proc ability (almost a full double proc), it would seem. I'm kinda just guessing how it works here, so if anyone wants to verify feel free.
