Town board task streak system (similar to slayer tasks) could be a nice/fun thing to have, without it being too OP:
- A multiplier is applied to the XP/points you receive from a task streak (every 10th, 50th, 100th, 250th, 1000th)
- Multiplier increases based on the task streak difficulty
Pros:
- This can be balanced easily since the multiplier can be low for the easy streaks
- Gives the town board tasks a bit of strategy fun - player can "optimize" their streaks by doing the task with best reward on their board as their streak
Cons:
- Slightly accelerates town board progress (probably a positive for newer players, while possibly negative for some existing players)
- No visibility on # tasks completed until the player completes another task
