what if lucian's second shot was treated as a spell?
This would mean it would no longer apply onhit effects like bork, pta, klepto but still apply effects like black cleaver stacks.
He can be given compensation buffs if necessary but this would be a really good way to stop him from abusing stuff with his passive interaction and balance him long term.
The second shot should still be able to crit, like anivia's E, if lucians first shot crits.
