Spell Fusion Ideas

[Erth16]

I am working on a game as a hobby. I intend for it to be a turn based strategy game, but if you scale down the battlefield sizes and number of participants the current design ideas would also work well as a trpg or miniatures wargame. There is a large class tree of martial characters, which aside from needing to fiddle with stat growth numbers, is mostly completed, and a few distinct casting classes, whose customization comes from the spells they learn. One of the key features of the game is using the terrain and altering it to suit your needs, through the use of magic and engineering.

The thing is though, I don't really have too many spell ideas to make the casters feel like they have a lot of choice. There are 10 schools of magic, Fire, Water, Wind, Earth, Light, Dark, Metal, Wood, Void (or Non-elemental), and Ice. Each school has 10 levels of spells, each level having 3 spells available, at least that is the plan. Additionally, most spells if cast simultaneously with one of similar level from a different school fuse into one of the subschool spells. This is where my question lies.

I was wondering if any of you had any suggestions for spell fusions? I of course came up with a few concepts of my own, Fire+Earth making an explosive spell, Water+Wind making a fog over an area to reduce visibility and accuracy, Metal+Earth to create a bunker where units can heal and hide from ranged attacks. I just would appreciate any suggestions, even if I don't end up using them they could spark some inspiration in me.

Thank you in advance if you have any, and thank you for reading even if you don't.

It sounds like you should rob spheres of power.

A possible suggestion is that you could have each element contribute something to the spell, for example:

Element	Target	Effect	Special
Fire	A 20 foot radius area	Takes a lot of damage	And is set on fire
Water	4 5 foot radius areas	Take some damage and are knocked down	And is slowed
Wind	A 120 foot line	Is thrown to the end of the area and takes damage	And drops something
Earth	A 40 foot radius area centred on you (but excluding you)	Takes a little damage and is stunned	And is knocked back and down.
Light	A 10 foot radius area excluding your allies	Takes a little damage and is blinded	And is illuminated
Dark	One creature, twice	Takes a fair amount of damage and is poisoned	And gets a penalty to attacks
Metal	One object, twice	Takes a fair amount of damage ignoring resistance	And gets a penalty to defence
Wood	Two creatures	Takes a little damage and is rooted	And is entangled
Void	Each creature next to you and/or a target ally	Takes some untyped damage	And is confused
Ice	A 30 foot radius area centred on you, excluding your allies	Is frozen	And is slipped

So a fire, air and earth spell could deal a lot of damage in a 120 foot line and knock creatures back and down, or deal a little damage and stun creatures in a 20 foot radius, making them drop something. For example.
