Equipment damage from enviroment effects and / or spells?

[carn]

Party with a gunslinger and a wizard dive to some undergroung location, protect themselves and equipment with some spells. (There are some, do not care too look them up).

Enemy casts dispel magic, protection spells get dispelled. Gunslinger and wizard start to drown, but can hold breath for some rounds, so defeat enemy lets say 3 rounds later and recast whatever keeps them alive. What damage is in the 3 rounds of full immersion in water without protection done to their equipment?

"Realistically" powder and spell book need to dried before they can be used and7or to avoid furhter damage. (especially wet book is in danger of being damaged accidentally).

But i cannot find any RAW mechanism.

Item damage normally seems only to happen after sunder attack or natural 1 saves due to energy attack, which neither happened.

Furthermore some time later they battle near a laval lake. Evil guys dispel fire protection and bull rush wizard and gunslinger into lava.
They climb out 1 round later.

They receive 20d6 dam in that round. As they do not make asave throw with natural 1 and as the lava lake does not sunder, they afterwards look per RAW (assuming level 10 or so) mostly like Anakin/Darth at the end of Star Wars 3, but their clothing, their backpack and most importantly their spell book and powder are completely undamaged.

Correct or did i miss a rule?

There are no rules for water damage if that is what you are asking. It is all GM Fiat.

As for the fire damage it normally just affects the players, and not the equipment. A GM could rule otherwise though.

So climbing out of the lava sea their silk clothing looks perfectly fine, except from the black spots caused by their flesh being burnt?

Thats funny.

And if immersion in fire does not damage equipment, immersion in water should not damage it either.

Well, in similar situations we've always houseruled that non-magical equipment gets damaged somewhat realistically, sometimes with a d2 to determine that.

Magic items (including spellbooks and component pouches) are normally safe, but if it's really a lot of damage, like falling into lava, they get to make their own saving throws.

Generally speaking it takes a failed save of a 1 to damage equipment. Though I think in the case of fire items can be lab led flammable. The only item I know of with a specific specific rule is necklace of fiteballs. It probly a a reasonable model to emulate for powder.

In the case of water, a can trip solves any issues of dryness. Spellboks are magical and you can probly assume the ink doesn't run like normal.

They are heroes. The reason they survive a lava-dip is because they have some innate magic/luck/fate etc. The same power probobly protects their equipment.
