There is a very noticeable lack of spells that create ice in the current beta. Those that are there are very limited in what they can achieve.
This is especially visible when you compare it to fire spells and effects. Anything that fire touches burts into flames.
Any flammable surface hit by any fiery spell turns into burning surface whole, covering a huge or very big area.
Fire destroys various containers by continuously burning, clears obstacles like poison acid sludge, and you have several offensive spells of it to use.
On the other side there is almost no spells that actually crate ice.
Only the ice spike for lower levels, basically. And ice arrows rangers have.
Both of these create only very small icy surfaces, even when aimed at a water surface - while fire makes whole surface burst into flames - and lightning makes a whole watery surface electrified.
The only spells that creates a bigger icy surface is Ice wall and Ice elemental when it dies.
At least those are the only ones i found. Both require higher levels - i.e. come to use late in the beta.
In general, magic is missing a bit more offensive spells for low levels. Earth spells were greatly improved by addition of the spider summon lately, but is generally very useful as a buff styled magic branch.
Air has blitz bolt, headvice, teleport and lightning strike, plus some very nice buffs.
Water could be a bit more diverse, and generally spells could have more synergistic uses and effects on each other.
In the starting lower levels.
Various kinds of clouds are creating a lot of problems now.
Maybe removing those, or turning them into something else would be a good use for some additional low level Water - ice based spells?
And the results of those could then be affected by other magic styles.
Black clouds could be dissipated with rain or by affected lightning spells?
Heated up with fire into becoming toxic?
Poisonous clouds could be affected by some cold spells or even rain spell, so they fall to the ground and become puddles?
Could they be blown into specific direction by some sort of gusts to do poisonous or corrosive damage?
