Throw on some
or
and some defensive item,
or
most likely, and you're talking about carry level's of damage on someone who can duel while only taking 60% of damage before resists, 20% if you're meditating.
If someone starts to build armor against you, just throw in a last whisper somewhere, and still melt them.
Keep on building Rageblade though.
