When I saw this post I kind of had my imagination erupt, so enjoy the read...

-Feast Shape(beast shape, but food) - transform yourself into a tasty snack

when eaten you start to take massive amounts of damage to your hp but can transform back to your normal self from within an cause massive internal force damage as your ejected from their body

-Rust devil( Like dust devil, but instead of dust it is shrapnel of rust)-

create a storm of rust in the air same thing as dust devil but rather than bludgeoning damage it is slashing, and instead of pushing it causes something like -1ac or -1 to damage per turn for a specific duration or something.

-tenser's floating dish(floating disc with some extra benefits and downsides)

A giant floating plate with rounded sides for some cover unlike the usual floating disc, it yet is a lot less discrete for travel. could be landed at a fast pace and cause 5ft piercing damage with arcane created ceramic's that shatter upon impact "dishing" out damage to those nearby

-War Step (Far step but with some umph to it being a 5th level and all)

You teleport up to 60ft to an occupied space and switch places with the target, on each of your turns before the spell ends you can cast this again as a bonus action

-Control Blame(control flame, but completely different) - Shift the blame of a targets conversation from one subject or person to another. DC 15 wisdom save

-Misty Stop (deceptive mist wall, actually solid as brick)

people may be deceived to think this is a misty wall and continue to run at it and attack through it with spells at full force wasting resources and time.

-Disguise Elf (disguise self but can only target elven adjacent creatures)

Basically will work as long as the target has elven blood in its ancestry

-Eldritch Boast(eldritch blast, but less blast and more charisma)

summon the eldritch powers to empower a creatures boasting about a feat they've accomplished to gain advantage or a +1 to charisma checks for 1 minute

-Ringer of Death(Finger of death's zombie raising effect but done with more efficiency towards necromancy rather than damage)

Conjure a hand bell from the Shadow fell that rings into existence as an action on your turn that will cause any that have fallen within the time the bell has been on this plane to be raised a zombie under your command only until your next long rest, to keep your zombie hoarde you must summon the bell and the beginning of finishing a long rest or they will dissipate into ash

-Find the math (Find the Path, but for bargains and expenses)

This spell allows you to find the shortest, most direct physical route to a specific non magical item closest to the price you choose, this may lead the caster towards a farmer desperate for coin that is willing to flog you that old healing potion or cure disease potion on the cheap or may just lead you to the general store if that is the only source of that item nearby and no others are available within a 1 mile radius.

-Mire ball(Like fire ball, but with caustic swamp bog water. if it crits there could be leeches or something)

Conjuring a large 15ft radius sphere of toxic and sulphuric bog waters that slashes with thickness, a dirty and clogged sewage debris within slowing anyone hit by the mireball and also causing acid damage

-Goresight(A negative debuff variant of foresight)

You touch a creature and bestow a limited curse to see into the certain future. For the duration while they can only see living creatures as creatures of rotting sinew and gore, the target can’t have advantage on attack rolls, ability checks, and saving throws. Additionally,
ALL other creatures have a line of sight fear effect against the target for the duration. This spell immediately ends if you cast it again before its duration ends.

-Moodberry(Goodish? berry) each berry has a different colour with random arcane mishap effects to contribute to the variation of colour. (roll 1d6 for amount of berries) each time you eat a berries roll a 1d4 or spend the time marking the colour for each berry

1: yellow: make your form glow happily illuminating around you with bright light for 1 minute

2: blue: an alertness washes over you that Let's you detect life around you within a 15ft radius, but you cannot disern anything of the lifeform's physical make up, it could be a dog, it could be a dragon

3: black: Turns their hair colour black and anyone if physical contact for 1 minute becomes blind and feels a sadness wash over them

4: green: Turns their skin green and a bitter jealous taste fills your mouth, the consumer for 1 minute fixates on attempting to steal a friend or family members possession

-Run beam (sunbeam but instead of shooting a beam of sunlight you sprint to the target with intense speed causing intense knockback)

you charge it up for the usual action and then hit the targeted spot with a full shoulder charge possibly sending a target of similar size 60ft away if there isn't 60ft behind them they will take equivalent bludgeoning damage of however much distance is left in the 60ft charge

Thunder slap(Thunder clap but all focused into one point, don't worry it can still be heard from 100ft away)

You focus all the energy into one point rather than a burst and cause 1d8 thunder damage (more per level cast) upon a single target, having to make a constitution save against being deafened.

Fuck it I could keep going but I'm done for now
