So I'm curious on the community's thoughts on lightning attack spells. Not counting buffs, they tend to have higher damage output and lower daze/stun chance than light attacks, and lower damage out put than earth and fire attack spells. Additionally lightning can deal dazes/stuns (like light attacks) as opposed to earth which can deal daze/slam instead.
Lightning attacks seem weird. Why would you use them for damage output when boulders and fire attacks tend to do more damage? And if you're going for effects, then why not just use light attacks?
The best I can figure out is that lightning attacks are intended to be able to do both the things that earth/fire and light attacks do, but just not as well as either. A relatively high dice attack with a kinda decent chance of daze/stun is still pretty useful. With lightning attack spells you aren't trying to kill an enemy creature as quickly or efficiently as possible like a rock, boulder, fireball or firestream. And your main reason for casting them isn't the daze/stun like it often would be with light attacks. Rather, the daze/stun is a secondary benefit. Having one or two less dice in the attack is compensated for by the daze/stun chance. (Of course you could be casting something like lightning jolt in which case the effect is your main reason for casting it (stagger).
Comparing arc lightning with flameblast, we see that arc only has 3 dice and flameblast has 4. In addition, flameblast has a good burn chance. So flameblast has close to an equivalent of 5 dice and unavoidable for 5 mana. Arc lightning has only 3 dice, but it does have a good daze/stun chance in addition to also having unavoidable, also all for 5 mana.
As stated earlier, lightning attacks are not for killing the Mage as quickly as possible. Here is the kind of situation where I suspect lightning attacks would shine. It is the end of one of your actions. There is a powerful active creature in your zone that will maul you as soon as it has the chance. (If might be the enemy Mage it might be something else.)
However it has already taken some fairly decent damage. You throw a lightning attack spell at it in the hopes that either the attack spell will kill it or daze/stun it. If it doesn't die but gets dazed or stunned, you will be able to finish it off later. And if it dies than you don't have to worry about it anymore. Throwing two lightning attacks in a row increases the chances that you'll land a daze/stun and it probably will do more damage. And if you successfully land a condition the first time you can wait until after that creature uses its action and the daze/stun goes away and then cast the other one after that.
In summary, lightning attacks are probably best used either:
-As a way to finish off a creature when it is sufficiently low on health with a decent chance to delay it from attacking again if it survives.
OR
-When you're casting them at least a couple of times on the same target so as to increase expected damage output and the chance of landing a condition.
In contrast, fire attacks are for doing as much damage as possible to a target as quickly as possible.
Technically since a burn deals about 1.5 damage on average and a lot of fire attacks have a small chance of dealing two burns instead of just one, fire attack spells probably tend to have about 2 more expected damage output than earth attack spells. But earth attack spells often have daze or slam chance.
Hurl rock has a worse chance of daze than all light attack spells currently in the game, and it's got a better chance of dealing a condition than arc lightning, but since arc lightning has a decent but still small chance of dealing a stun condition which is more powerful than daze, that probably makes up for having a 1/6 lower chance of landing a condition.
Hurl boulder has a slightly lower chance of landing a condition then lightning bolt has, and slam is less powerful than stun but more powerful than daze. Meanwhile lightning bolt has a higher chance of daze and lower chance of stun than boulder's chance of slam is. Hurl boulder does 2 more dice than lightning bolt, but notice that lightning bolt's stun chance is one of the best in the game and also has ethereal. The excess chance of stun compared to other attacks which can deal stuns makes up for the two less dice.
As stated earlier, earth attack spells do not have as much expected damage output as fire attack spells. While earth attacks tend to have one more die than their Fire counterparts, fire attacks have a good chance of dealing burns which always gets past armor and rolls more net damage on average than a die rolled in an attack.
This concludes my analysis for now. I might write about wind vs hydro vs earth attack spells later on, but no promises! If someone else wants to write that article first feel free.
