As it is now:
A Sophisticated Pillager or Streetwise Negotiator -skilled scout/explorer may bring a bonus quest upon reward(s) from related search.
However, those quests are unique and "flat" (not tiered); which means any brought quest you already have, is lost (opportunity).
Also, despite having a skill bonus quest, some adventures are still not attractive enough to be played.
My suggestion:
Add tiers (with incremental reward) to Skill bonus quests.
How it would work:
If a Sophisticated Pillager or Streetwise Negotiator -skilled scout/explorer brings a bonus quest you already have, then a tiered up version of that quest will be added.
Ie a tier 2 version task requirements are doubled, a tier 3 version task requirements are tripled and so on till max tier (could be 5).
Eg a tier 2 version of Bonus: "Wild Mary" would require Complete the "Wild Mary" adventure twice. Rewarding twice (perhaps or tweaked numbers) as much as tier 1 version; a tier 3 version of Bonus: "Wild Mary" would require Complete the "Wild Mary" adventure three times. Rewarding three times (perhaps or tweaked numbers) as much as tier 1 version.
Let's say..
- ..you complete a Wild Mary adventure while having the according Skill bonus quest tier 1, 2 and 3. That would complete the tier 1 quest and make progression in tier 2 and 3.
- ..you then get this skill bonus quest again and again. That would first add a tier 1 quest as there's none, and then add a tier 4 quest as there are already tier 2 and 3 quests.
- ..you once again complete a Wild Mary adventure. That would complete the tier 1 and 2 quests, while tier 3 would progress to 2/3 and tier 4 to 1/4.
Conclusion:
By implementing this suggestion, there would be no more wasted quest opportunity on a second find and former unattractive adventures could become attractive enough to be played.
To get it all well-balanced, some numbers and variables (chance to get a quest) would probably need to be tweaked, but tier set is limited so shouldn't be that hard to do.
There might be other issues keeping players from doing some adventures, but this suggestion is about the reward - what you'd get as bonus when finishing an adventure, not how you'd finish it.
