Breach, Mord and Stacking question

[Mudeye]

I have another question about spell effects. I've read that Energy Drain stacks and can reduce targets stats lower and lower.
Breach spells strip Defensive buffs and reduce SR.
If I breach over and over will it remove more and more defensive buffs?
If I breach over and over will the targets SR continue to go lower?
Does anyone disagree that Energy Drain can be stacked (or Enervation for that matter)?

Continuous breaching will result in all breachable buffs being breached.

SR decrease from Breach, Mord, Dispel does NOT stack.

The level drain portion of ED and Enervation can be stacked to the enemy's death (If they are vulnerable to level drain).
