Expedition: general discussions.

That's an interesting point. Did Revan simply refuse, or was it a matter of you not reaching the correct location and talking to the right person?

Well, how can I put it... One guy asked for 500 resources, which I didn't have. Another guy asked for 200 resources but didn't want to show the "item." He wanted me to pay first, and then it would turn out that it wasn't what I needed. I could have given him 200 resources, but not for a "pig in a poke." A third asked for 300 resources. But it was "money in the morning, the goods in the evening." And the fourth gave the character Loken a cool katana for free, but first insulted me and then killed me... In short, judge for yourself, but I think he simply didn't want to give it...
And I'm not going to tolerate this kind of attitude from NPCs towards player characters without the option of "giving them a beating."

I can assume that such an item simply didn't exist in the game mechanics. And if Revan had given it, the game would have introduced mechanics for wet characters, equipment loss due to water, and other things that would be inconvenient for other players.

I once asked, "Are backpacks in the game waterproof?" Revan ignored my question. Then I tested it with a "towel." It turned out that it doesn't protect.
And this isn't about "swimming," but about "being underwater for a long time." And yes, "it didn't exist" for me. I think for another player, it might have... And not because "the GM is a nasty guy," but because I allowed myself to "consider different options" instead of "going with the flow." It seems that's not appreciated here.

We're talking about a case that would protect Yaschur's equipment from water. Yaschur's champion was leveling up in a water-based religion and really knew a lot, but... all the battles in the main game were strictly land-based. Nowhere was it said that such an item was needed. Or that it even exists.

Astral, you should take a look at where the obelisks are located... I managed to read half of your AA. Whirlpools, icebergs, pirates... I already know all this. So, no need to...
