New Niche AP Items and another AP Passover

I was on a 3 hour drive back home by myself so I took some time to spitball some ideas for new niche AP Items that I thought up and some I have seen the community talk about. These are just spitball ideas I did for fun so dont flame me if they are bad. These items could also be balanced better if they turned out broken etc.

Riots goal for the recent AP Itemization Passover was to limit the standard AP build and make it where each item you get is a decision and tradeoff. Just like before there is the same basic build that mages want,(AP,Mana,CDR,Mag Pen) Mana item, sorc boots, morello, void staff, deathcap and usually a zhonyas. These changes and new items below imo offer up that goal. Every item you build has a reason and a tradeoff.

AP/MR Item- Abyssal Scepter- old item but changed up a little bit Ingredients: Stats: 60AP 55 MR Passive Changes: No longer gives CDR, removed passive New Active: (120 sec CD) once activated gain the Abyssal Aura (30 sec) and your next damaging spell against an enemy lowers the enemy champions MR after damage from the first spell and empowers your next Spell/Auto attack dealing 10% of your current bonus AP Reasoning/Tradeoff: lower AP/MR item than Banshees and with no CDR/M Pen/Mana shouldnt be a rush item, if rushed the tradeoff being no Mana, CDR, Pen and lower amounts of AP. The active makes it a better scaling option and this is meant to be more for Burst Mages and Assassins while Banshees is for traditional Mages

AP/ARMOR Item Ingredients: Stats: 55 AP 50 Armor Passive: Lifeline(like Maw or Steraks) about time AP champs got the same option for the lifeline passive- basically the opposite number of MAW Reasonings/Tradeoff: again lower AP, no CDR,PEN, or Mana so not likely to be rushed but great to build if you dont normally get Zhonyas and late game they have a fed AD champion. Worried this could stack too well with Zhonyas so potentially lockout the ability to stack them if its too good upon testing. Its a purely defensive option for a mage who is giving up valuable stats for safety.

AP/ATT SPD/Mana Item- my personal favorite idea Ingredients: Stats: 30 AP/25% ATT SPD/250 Mana Passive: For every X amount of attack speed you build you X amount of AP Max of 45 AP(75 total item) Reasoning: Nashors Tooth is also a niche item as is but i thought it could use something to synergize with and its not something normal mages will want because it has no CDR,PEN and low AP that only stacks with SPD. Good niche item for Azir, Teemo, Kayle, AP Varus, Nashors Tooth Orianna build, and some other mixed dmg champs. Just a cool idea i thought.

AP Grievous Item Ingredients: new small item that gives 25ap and the grevious wounds passive, Stats: 65 AP Passive: grievous wounds Reasoning/Tradeoff: grievous wounds should be something that is built for a specific purpose not an autopilot reward. Thought it would be interesting for this item to also give spellvamp so its kinda like im hurting your spell vamp and taking some for myself

: remove grievous wounds passive, players shouldnt be rewarded with grievous wounds for building an item mindlessly for the AP and Pen.

: up 5 AP and 50 mana to give it 300 mana which is half of a Lost chapter item

: give it the old ludens passive for build up from movement instead of the current build up from spells. Riot hurt waveclear bc mages were slinging spells too much so it really contradicts what they wanted.

: build out of maybe also give this the lifeline passive

Sorry for the big post but let me know what you guys think! Again every item you build should have a reason and a tradeoff, not the same build over and over. To gain safety you should lose some other stats as a tradeoff and if you go with the same standard build thats ok these are just niche items for certain circumstances, however, you'll still be glass cannon.
