Adding a "scaling" to Duskblade damage

Nah, not talking about scaling with AD or AP, but making it a true assassin item that needs to be built up :

Each kill (or each few kills) would increase 's base damage, instead of having such a high base damage that doesn't scaled with AD, the same as "Legend" runes work.

Would be really cool, because it wouldn't reward a 0/3 or 0/4 assassins building it and being allowed to 100-0 his laning opponent that is 4/0, and it would actually make them feast or famine. It would also feel less overloaded imo.

My 2 ideas are either :

• Add a static limit to its damage that wouldn't feel overbearing
• Add a "huge" limit (same as ) that would reset / lose half its stacks upon death
