^You better check it, then. Any damage coming from AD, Sheen, Trinity or Iceborn (Only the original target, not the whole ice field) is turned into magic damage and procs spell vamp instead of life steal.

This is because, except for Jax's Empower, AA resets that deal magic damage turn the whole damage (The physical damage from the proccing attack include) into the ability's damage instead of applying them separately.

However, since it's an old game mechanic that has not been updated in a long time, the on-hit damage from Muramana and BotRK are not turned into magic damage.

Test it, you'll see this is how Devastating blow works.
