Continuing from this question

  • This bomb is supposed to work with any ordinary piece of wood in the wild. But the wood in the wild is often wet. How much of problem water would be? Pyro Mana can detonate the wood regardless of presence of water. But water can suck energy out of resulting explosion. Moisture will be produced in the process. The Bomb relies on atmospheric oxygen to burn the wood fragments once the stored oxygen has been used in the initial explosion. Will moisture restrict this? If yes, to what extent?

  • $\begingroup$ No, I am asking will an explosion will be hampered by moisture in wood. Mana will ignite the wood regardless of water. And there is enough oxygen for an initial explosion. But after that atmospheric oxygen is required to carry on the explosion. How much will moisture hamper this? $\endgroup$

    $\begingroup$ Detonation is not the same as combustion. If your magical Pyro Mana has created an explosion, it's too late to start worrying about whether the wood will subsequently burn. The only way the question even makes sense is if the Pyro Mana is a magical trigger stage that turns the wood into sawdust, disperses it and then ignites it (ie a dust initiator, the same effect that causes grain silos without anti-static measures to go boom sometimes). That does not seem to be what you are describing. $\endgroup$ May 16 at 7:41
  • $\begingroup$ Changed combustion to detonation. it seems you should research what detonation is vs combustion. $\endgroup$ May 16 at 19:35

Pyro Mana can ignite the wood regardless of presence of water.

This alone kind of answers your question. If Pyro Mana can ignite the wood regarldless of the presence of water, then it means the Pyro Mana must by necessity burn in some kind of extremely intense exotermic reaction, like magnesium, Thermite, or sodium. In fact, some materials burn SPECIFICALLY when water touches them, with H2O being the catalyst. In pretty much all cases when material burns regardless of the presence of water, it is because it burns with intense enough heat that water evaporates on contact entirely, or because it reacts explosively with water itself (usually by breaking off hydrogen and oxygen out of the water itself, and using it as fuel).

Any kind of Pyro Mana that could ignite at all in such scenario, will be one that would burn anyway, even if you doused it with water. The process required to self-ignite explosively in such condition releases enough energy (and thus, temperature) to make water irrelevant.

I think you should reimagine Pyro Mana as less something like gunpowder, and more like magical magnesium, that burns insanely hot, and only explodes because the gasses have nowhere to go. The first option will not give you the power and reliability you want, the second one will.
