Ap Duskblade as solo assassinitem

This Post is for an Ap Duskblade. I dont know at the moment the 4th Assassin for the Big Chances, so i think its Kata or Fizz while mentioning below their actual gamestyle and abilitys as examples. Feel free to make a better name as Ap Duskblade so we have Duskblade of Draktharr and ...blade of ... I dont know how you support and handle Comunitysuggests, if the item includes my name "Haexel", its ok, if not, doesnt matter, the item idea is the important one ofcourse.

Ap Assassins whith the exception of Kata and LeBlanc often buy Lichbane. Lichbane is mostly build on Fizz, Diana, Akali, Eve, Nida and Ap Ekko. Ofcourse Lichabe is for some rangeusers good too like Sona, TF and even Vktor, but the majority of Mages dont buy it cause theiy either autoattack much or want just more ap from stronger items cause their autos have ap scalings. So autoattacking is a thing for Fizz or ekkoplayers cause they have abilitys with passives on auts or make them empowered for a short time while having abilitys or the concetp of a melee to even stay near the target for their abilitys like kassadin jumps with r on you, slows with e, does empowered w and than could maybe after a q and 2 addional autoattacks jump away.

So a Duskblade which gives magicpen and occurs his magicdmg Nightfall not after one auto, but after one ability and maybe 2-3 basicattacks on the SAME champion, would work for ap assassins, skirmishers, divers, not for burstmages. The reason for not after just one auto is cause Mages while autoattacking not so much, after a few abilitys they use some autos too like ziggs and lux with their passives. So the passive rly needs one ability and 2 direct autos and if it would be ability, auto, ability, the 2nd ability would reset the autocounter in the same way how ryze runes for his q resets. Lux for example can make ability, auto, ability, auto, for highest dmg output by consuming everytime the lightmark, but doing after one abilty 2-3 autos and than the next ability is not her style in teamfight cause she wants to hit stun or slow for hitting easier Final Spark and Lucent Singularity/Light Binding and for combos like that the time is not enought for multiple auoattacks. Fizz/Ekko/Kassadin can jump on you with e/q/r and do their empowerd autos between their abiliys like fizz uses q, r and ignite, activates w, uses 2-3 autos and than use e either again on the target or to escape with that while his targeg will be if not already be dead in a few seconds with ignite, w, activated nightfall and ultdmg. Kasadin and Ekko can use that too, even Leblanc could use that on some tankier champs while the chain is on and the rest of her abilitys are on her short cds. But for that be balanced she should q(r)w to a target and kill the next one with 2 basics for the nightfall and and than her cds are back. Nightfull should activate with one ability and 2 autos on one target, targetswitching resets the counter too. Ofcourse the Ap Duskblade could be used on normal mages for trading in Lane too, but that would be with a 120s CD not worht, if you later in teamfight cant activate it cause you are brandt and uses all abilitys and than your autos cause brandts combo should either kill them before or brandt self should be dead after his combo while even if both is not true his aoedmg makes the solotargeting for nightfull nearly imposible. So the Apduskblade is for Assassins who are using Autoattacks, Spells and do not use Aoedmg. For me this could be less abused on other classes as the Duskblade of Draktharr, which is acutal an item Jhin and Mf players like to build.

Maybe the Ap Duskblade is than just an item for Fizz, Kassadin, Ap Ekko, Akali, Diana, maybe Lb and TF can work with it too by using goldcard and his basics, but i think a good reason reason for putting that into the game is because the melee ap assassins have the same items as the mages beside not buying the big Ap-Manaitems which they dont need and instead of that going Lichbane (for the Sheendmg, not the Mana it brings). They go maybe not Rylais, but if Items like Ludens, Rabbadons, Zhonyas, Abysal and Voidstuff are geting nerved cause mages are to strong with them, than the Ap assassins suffer from that the most. New Items like an Ap Duskblade or maybe a Morellonomicon without Mana cause they could handle some Cdr and a passive for being good against playing vlad/Mundo/Soraka would help them.

But i dont know when we get the Assassin Roster Update and if you like my Idea/test it, but im already hyped for it, for Yorick, Warwick, knowing if after saying the 4th Assassin going for big changes is an Ap one is either be Katarina or Fizz in my Opinion, interested what you make with Rengar (ADC main), seeing and testing the Changes on Talon on the Pbe, seeing which other assassins you change a little like kha eveltionchanges or if kata is the big one what fizz gets for little changes and i hope Leblanc will still be fun to play with more Waveclear after all. You do a great Job, i feared as i fear now for Lb, myself for the malzaharupdate but it was a good look on the abilitys and i still like him to play as much as before, so i hope same comes for Lb. And if Talon interests me, i add him like i added Swain, Ryze and Tristana after your good work (i dont know which or if even one Riotemployee reads (till) this).

Hope this Post wasnt to long/boring/bad time to post. I dont know how to end this post. Thats it.
