Chapter 3418 Arcane Fire Advantages Detection Limit
The elemental plane after breaking through the material boundary is different from the elemental planes discovered before Shado or Netheril. Those elemental planes that can be called planes are essentially material planes.
It is only because they have more extreme elemental tendencies that they are considered elemental planes. They can actually be the source of elemental energy when casting spells, but they are not true elemental planes.
The real elemental plane should be a force, or a rule, located inside matter and used to support the formation of matter and even elements. It is the cornerstone of the existence of the world, rather than individual planes.
The arcane fire is connected to such a real elemental plane, so it can break through the power limit of the magic network. Regardless of its size, the essence of the arcane fire is actually the same as the magic network.
They are both special structures that can be linked to the elemental plane to draw energy from them for the caster to use. The only difference is that the former is man-made, while the latter is natural.
When civilization develops and utilizes them, natural ones are not necessarily better than artificial ones, just like the difference between wild drugs and synthetic drugs in Xia Duo's hometown. He actually trusts synthetic drugs more.
After all, the synthesis path is certain, the relevant mechanisms are certain, and even the side effects can be certain. However, there are too many uncertainties in wild drugs. In comparison, synthetic drugs are more trustworthy.
The same is true for the Magic Network. The birth mechanism of the Magic Network in the natural environment is unknown, and there are still a lot of unexplored aspects of its own rules. Compared with the arcane fire that the caster has "measured" from scratch, it is obviously an arcane fire.
Fire is more reliable.
Various accidents may occur in the Magic Network, but as for Austrian Fire, as long as there are no mistakes in the production process and the operation process, the result will definitely not go wrong. This is the greatest value and advantage of Austrian Fire.
Even if it is not as good as the natural magic network in some aspects, just because it can break through the power limit of the magic network and is controllable enough, it is enough for any arcanist to use it as the best choice when casting spells.
Anyone who thinks arcane fire is not good has never used it personally. Those who have used arcane fire personally and still say it is not good can only be because the arcanist has a problem with himself. He was lucky enough to advance successfully, and his understanding of magic is actually fundamental.
Not worthy of Austrian Fire.
…
Xia Duo transformed into earth and stone to communicate underground. Even if there was interference from the radiation from the earth's veins, the spell itself was still normal. This was the effect of the independent magic network controlled by itself. Even if it continued to go deeper, it would still not be affected.
Not only the [Stone Walking Technique] he cast himself, but also the [Wide Area Detection] inspired by the robe of longing was not affected, because the robe of longing also has its own arcane fire.
Of course, the fact that the spell itself is not affected does not mean that the external effects of the spell are not affected. Just like shooting at wood or iron plate, you can shoot, but the effects of bullets are completely different.
In an underground environment, the external effects of detection spells will be affected. This has nothing to do with the spell itself. Unless it is a guided spell, it is generally believed that the spell effect has no connection with the spell itself.
Just like an electrical appliance on earth, no matter what environment it is placed in, as long as the circuit is not disturbed, the electrical appliance will operate normally, but the effects it produces, such as sound and light, will change with different environments.
The stabilizing effect of arcane fire on spells is equivalent to the protective measures used by electrical appliances on the earth to protect circuits from environmental interference.
Now, although the spell itself is not disturbed, the impact of the underground environment on the [Wide Area Detection] effect is still very obvious.
Originally on the surface, [Wide Area Detection] was enough to cover the entire main plane. Of course, the farther the distance, the worse the detection effect.
But underground, [wide-area detection] firstly has a limited coverage, and secondly, the decline in detection effect has become extremely exaggerated.
Xia Duo initially judged that the decline of the detection effect of wide-area detection underground is mainly affected by two parameters. One is the range, which is the straight-line distance from the source of the spell.
The other is the vertical depth.
Both parameters affect the detection effect of this spell at the same time. The effect of range on the effect is roughly linear, that is, the farther the distance, the worse the effect, but the effect attenuates relatively evenly.
However, the parameter of vertical depth below the ground has an exponential impact on the detection effect, and will eventually approach zero infinitely.
Based on this characteristic, we can also roughly infer the detection limit of [wide-area detection] underground.
If the spell source point is placed at 0 height on the surface, then the detection range underground is almost a shape that covers the entire surface of the main plane, but is rapidly converging downwards.
The deepest detection depth is about 5 miles directly below the source of the spell, and other places are less than 5 miles deep.
If the spell source point continues down, the detection range will be almost the same. The deepest point will not be more than 5 miles away from the spell source point.
This is uncomfortable. Even if the entire Elam region is scanned, if the depth is only 5 miles, it may not be able to reach the Underdark.
If you cast a spell on the surface, no matter where it is in the main plane, the deepest point of the spell source can only be projected to about 5 miles underground. In other words, the ultimate detection depth of the [Wide Area Detection] spell is about 10 miles.
The detection depth of 10 miles underground is sufficient for war spells and any surface war.
After all, conventional detection spells can penetrate five or six meters underground, which is quite good. Ten new miles is a crushing advantage.
But 10 new miles may not even be considered a surface for an underground world that has not yet been explored to its limits and can actually be considered infinite.
In this case, if you want to detect deeper places, you must either change the detection spell to a more suitable underground, or you can only let the "caster" go underground.
In this situation, Xia Duo had no choice but to choose the latter.
Depending on the carrier of [Wide Area Detection], the corresponding method is to drive the floating city underground, or he himself goes underground with the robe of longing.
"I didn't expect that I accidentally chose the most correct way to do this in person!" Xia Duo couldn't help but sigh.
So he immediately took action, moving underground with the robe of longing, becoming a veritable human flesh detector.
…
On the other side, the Alliance mages at the rear, despite being distracted by the local battlefield where the time-related signal originated, still paid enough attention to this key clue that Xia Duo brought back from the bottom of the sea.
Soon, while Xia Duo was still moving back and forth underground to act as a human flesh detector, the command network was quickly synchronized with the locations of several suspected underdark passages that had been initially determined by the rear methodian's analysis of the detection feedback data.
