I drew a 3rd and 4th possible conclusions from those same facts.Astelon wrote:n7axw wrote:Imagine, for example, dragons soaring high enough above an advancing Sharonian army to be out of range of its artillery and drop crystals with explosive spells powerful enough to level a city.
The problem here is that Arcana has shown no capacity to make delayed activation spells that powerful. In fact the only delayed activation spells we have seen are grenades and the Arcanan version of landmines. Furthermore at Fort Salby the engineer who demoed the forts walls was killed by falling debris. The text even indicates it wasn't an unusual occurrence in demo work.
We can draw one of two conclusions from this:
1. Arcana has complete disregard for their own trained (and somewhat rare) personnel.
2. Arcana is having difficulty with delayed activation spellware for spells above a level of power.
The text indicates conclusion one is not likely, so I am speculate that it is the second. The second conclusion also explains why both armies were destroyed in the only mention of mass destruction spells being used (although it may have been made impossible for the losing army to withdraw).
3. A delay triggered spells may not have any adjustability.
The demo spell wasn't just trying to randomly blow something up; it was trying to create a practical breach in the walls; which takes more a random big explosion. The necessity to correctly place, and then tune/adjust the spell so it completes its creatively controlled demolition may take hands on gift.
4. Arcana's practice may be assuming rapid and effective counter-spells to be employed. We know spellware exists to find the landmine style "trap spells". It's possible they use no delay on their demolition spells not because they can't add a delay feature; but because they expect the spell wielding other side to be able to hit it with a disarm spell if given noticeable time between setting and triggering the spell.
I'll also note that we don't know how powerful their landmine style trap spells get; so it may be premature to assume they top out an anti-personnel landmine level. After all on Earth people also build anti-tank and, later, nuclear land mines!?!. We do know that they have the cut at Trailsum rigged for demolition; and I got the impression those are remote or delay triggered spells; not engineers camping out along the walls waiting to blow them. If so, delay or trap triggered spells capable of collapsing walls of a hard-rock excavation are pretty damned powerful...
