At long last, I completed the Storm King's Thunder campaign, the last of the "old" campaigns that were still lingering as incomplete on my main's campaign screen. Even though I already had partial completion when I started on my project to finally finish it up, it still took me three months of near daily play (admittedly not involving maximum effort, but still) to complete all the boons. Seriously, three months! The grind is real.
What's interesting was that the Voninblood, whose number requirements looked the most intimidating initially, didn't turn out to be that much of an issue. As Joseph Skyrim noted in a comment on my original post about the campaign grind, the Ostorian Relics you can collect on all four of the campaign maps and which can be traded for Voninblood largely make that particular currency a non-issue as they can be farmed easily and indefinitely. I just didn't realise this right away, which wasn't helped by me not even having a trowel (required to collect them) for a lot of my early play sessions. Also, duoing with my pet tank initially meant that each of us only got half as many relics as a solo player would have collected.
I soon found that everything seemed to hinge on Secrets of Ostoria, the currency associated with completing the main daily mission (which in turn required you to do one regular daily quest in each of the first three zones). I eventually realised that I could actually collect all the various dailies to save them up for later, they just wouldn't show up if I didn't also have the main daily in my log. I then settled into a routine of doing a whole batch of dailies in each zone on different days of the week while also saving up the completed missions to hand in one at a time each day for the overarching daily quest. If that sounds a bit convoluted that's because it was.
Sea of Moving Ice was a different matter as there was a limited amount of saving up you could do in that zone, and eventually I had to focus more attention on it as I just needed Runic Fragments (that map's unique campaign currency) to complete the last two boons. The main two lessons I took away from that were that the fishing daily couldn't be "saved up" as it auto-completes as soon as you've gathered the required amount of fish, and that "Recasting Alarm" could be abandoned and re-picked until it gave you the super easy circuit just next to the base.
All said and done, I do have to give credit where credit is due though: The zones themselves were enjoyable, with nice visuals and music, and I still enjoyed questing in them again. I just wish the campaign didn't require you to do it for quite that long.
