DPSing as a healer - best practices

[FinagleABagel]

This is true. Dot ticks don't break the sleep (neither does Flash). Bane spreading dots to your target will similarly not break the Sleep. However, reapplying dots directly will break it.

Yes, most people should notice that there is an initial hit potency and a tick potency. That's why direct hits cancel sleep, it's effectively no different than casting Ruin on them.
