+| Priority | Quest | Notes |
+|----------|-------|-------|
+| 1 | `FightBeastsAloneQuest` | Send an expendable hero (significantly weaker than the quest-giving hero) to fight beasts alone, since the hero will almost certainly die. |
+| 2 | `BattalionDiversityQuest` | Hire a battalion type the faction doesn't already have. Only attempt if the province has sufficient development to unlock the needed type. |
+| 3 | `BetrayAllyQuest` | Break an alliance with the target faction. Only attempt if: (a) the faction does not share a border with the target, and (b) the hero sent to deliver the betrayal is expendable, since they may be imprisoned. |

-### Special Event Quests
-- `FightBeastsAloneQuest` - Fight beasts alone

-### Miscellaneous

-- `BetrayAllyQuest` - Betray an allied faction
+- `UpgradeBattalionQuest` - Upgrade a battalion to minimum armament/training. May require development the faction doesn't have.
+- `BorderSecurityQuest` - Have troops in a border province. Involves taking provinces; better left to organic expansion.
+- `DefeatFactionQuest` - Defeat a specific faction. Too risky to pursue proactively.
+- `SpecificExpansionQuest` - Conquer a specific province. Too risky.
+- `ExpandToProvincesQuest` - Expand to control a certain number of provinces. Too risky.
+- `WinBattleOutnumberedQuest` - Win a battle while outnumbered. Can't reliably engineer.
+- `WinBattlesQuest` - Win a number of battles. Passive.
+- `RescueImprisonedLeaderQuest` - Rescue an imprisoned leader. Complex multi-step.
+- `WealthQuest` - Accumulate gold and food. Happens passively.
+- `RepairDevastationQuest` - Repair devastation. Happens passively.
