Man, going into the powderstone quest unprepared is not fun. :lol I failed a bunch of times: once because I pressed the wrong button at the chest, causing me to put down the stone (which promptly explodes) and the second time I was steps away from the last zone with the rock and I dropped it for no apparent reason (I think I wasn't watching my stamina, but still).
Other times my heat resistance would wear off mid trip, causing me to take damage from the stone and the heat, or a big monster would find me and mess me up.
I finally took my old Hunter's armor set, put a +4 transporter charm with it, put in a bunch of decorations to activate transporter, and made that my "these egg quests are stupid" armor set. Now I can see where any big guys are and avoid them, plus I'm more efficient when carrying things. The low armor isn't much of a problem because I don't plan on engaging anything in a fight anyways.
I went back and did the wyvern egg one with this set and I'm REALLY happy I didn't attempt it without it. There were a couple times there where I'd narrowly avoid walking right into a Rathian that was flying around because of the auto tracker.
With those done I now have more then enough commendations, so that means I only need one more firestone and I can make the skull mask (which I didn't know existed before it appeared at the blacksmith). Cool stuff!
