I love some of these (especially the arcane ones *cough*) that you all posted! I may add more later, or icons, but for now, there's these--bear in mind I'm still quite new so some may be too similar to existing spells in name or implementation. I did try my best to read over the Magicka list, though! I know Warm is a bit close to Heat Up.

Spell Name: Weave
Element: Plant
Intensity Level: High
Spell Type: Manipulation
Describe It: The user weaves existing plant material such as roots, vines or thin branches with living flesh. This can have the effect of closing wounds, strengthening weakened muscles or reinforcing healthy ones, but use on healthy tissue may weaken it due to the perforations. Very draining, and very risky, as a body--particularly one not attuned to plant magic--may reject the material and become infected or even necrotic. The plant life must be constantly monitored and maintained, and may die on its own and require removal after a short time regardless.
Icon:

Spell Name: Warm
Element: Fire
Intensity Level: Low
Spell Type: Manipulation
Describe It: The user carefully raises their body temperature to provide a gentle warmth to themselves and a small area around them. Useful for keeping them and their comrades safe in deep cold, for cold-blooded creatures, or when wounded and unable to regulate temperature. Care must be used to prevent the spell causing contact burns, or igniting out of control.
Icon:

Spell Name: Puppet
Element: Fungi
Intensity Level: High
Spell Type: Offensive
Describe It: A hostile fungus infiltrates a creature's brain, reprogramming its behavior and thoughts for a short time. The target may be aware of what is happening but has no control over their actions--instead, the caster does. The fungus variety is very fragile, and thus the control wears off within a few minutes--and must also be physically placed on the target's head. Should the caster hold onto it too long, it may sieze control of them, instead, rendering them comatose for a time.
Icon:

Spell Name: Spirit Sight
Element: Arcane
Intensity Level: High
Spell Type: Transformation
Describe It: The user shifts their consciousness into the the world of the unseen. For the duration, their body is helpless and they will not be aware of the real world left behind--instead they will see cryptic glimpses of any present magic, spirits, echoes of prominent events, or fields of energy of any kind. They may also be able to see the magical fields of those who have cast themselves into invisibility.
Icon:

Spell Name: Flash Freeze
Element: Energy
Intensity Level: High
Spell Type: Manipulation
Describe It: The user draws a vast amount of energy from a small focus point, sapping it of heat very quickly. Water becomes ice, and living things may quickly succumb to frostbite. Extreme caution must be used in dissipating the extremly volatile heat energy removed from living creatures, however--it can quickly overwhelm the user, even igniting them in spontaneous combustion.
Icon:

Spell Name: Reflexes
Element: Animal
Intensity Level: Medium
Spell Type: Transformation
Describe It: The user heightens their animal instincts, greatly increasing their perception and decreasing their reaction times for several minutes. This functions much like an adrenaline rush, and can compound the effects of one. It also shares the same drawbacks: the user will be left exhausted, often mentally as well as physically, the moment the rush has left them. Someone who experiences a powerful emergency adrenaline rush in conjunction with using Reflexes may even be left unconscious for a time.
Icon:

Spell Name: Translocate
Element: Arcane
Intensity Level: Medium
Spell Type: Transformation
Describe It: The user rearranges reality, translocating two objects. They may use this to instantly exchange the position in space of any two similarly-sized (in volume, not mass) physical objects, including living things. This is instant, but fairly draining, and runs the risk of embedding one or both target objects partly in the ground below, necessitating another translocation or physical excavation. Overuse in a short period of time may cause the object to become unstable, potentially weakening structurally.

I had some last-minute ideas

Spell Name:Absorb magic/ fuse gem
Element: na, maybe purchase per use
Intensity Level: high
Spell Type: manipulation
Describe It: Allows a user to absorb magic from a stone, or fuse a gem to themselves, acquiring attributes from that gem. Could be a gem from another gembound. Effects may be life threatening as you would be combining two energies.
Icon:

Spell Name: Defuse gem
Element: na
Intensity Level: high
Spell Type: manipulation
Describe It: defuse a fused gem, lost the magic, but also maybe some bad side effects. Extremely taxing on the creature. If one defuses their own stone, they will die.
