New Summoners to fill that bot lane void (and other places too)

I have noticed a stifling amount of supports running ignite in the bottom lane. Not that it is bad, it is just they were pushed in that direction because slows no longer stack and exhaust has less value on a lot of supports now. I came up with a few summoner spell concepts to fill a bit of a void in the bot lane and add variety in other lanes. Feel free to let me know if they need tweaking and let me know why you think they need tweaks.

Investment Cooldown: 150 seconds Range: self The next time you would gain gold in the next 5 seconds, double the amount gained (gold modifiers such as machete, draven passive and parrrley bonus gold do not add to this)

Conjure Cooldown: 180 seconds Range: 900 Summons a wall 450 units in length for 3 seconds. Can reactivate to dismiss the wall (if cast on top of an enemy champion it will put them on the side farthest away from you. If cast on an ally champion it will put them on the side closest to you)

Poison Cooldown: 210 seconds Range: 600 Deals 50 + (20 x Level) physical damage over 5 seconds. Target's armor is reduced by 7% every second for the duration of Poison (35% at 5 seconds)

Decay Cooldown: 210 seconds Range: 600 Deals 40 + (10 x Level) magic damage over 5 seconds. Target's magic resist is reduced by 6% every second for the duration of Decay (30% at 5 seconds)

Gravity Cooldown: 210 second Range: self End all movement based crowd control and become immune to it for 5 seconds (Knock ups, pulls, knock backs, etc.)

Investment is made to award slower play and be able to benefit off it. I am hesitant to make the cooldown lower because it can then promote snowballing but I think 120 seconds might also be feasible

Conjur is to add an additional peel option in to the kits of champions who already have slows. People may flash it but its CD is shorter than flash and in the later teamfights it splits the team down the middle which allows better wombo. Very similar to anivia wall

Poison and Decay are to give a better late game offensive summoner. They aren't the strongest early game (where you would take ) and they don't deal true damage, but they help to get through those oppressive tank lines. Decay is lower shred and damage because MR is strictly harder to come by.

For gravity, I personally have been feeling that displacement CC has been to strong because it doesn't have any hard counter ( aside). Also here to force those and mains to have more skill ;P

Lemme know what you think! (tried to make art for it, but I am awful so I spared you all the trouble)
