Start with Proficiency Enhancements, then prioritize Drive nodes, and move into Aether plus Restoration once that branch opens. That is the clearest early-game priority stack in Sorrow’s Serenade, because it covers the three things that matter most in its roguelike mechanics: damage now, faster meta-progression later, and enough sustain to keep runs alive long enough to benefit from both.
If you only want the short version, treat the skill tree like this: Proficiency = offense, Drive = economy, and Aether = endurance. The most common mistake is over-investing in health or niche utility too early and slowing your whole account progression in the process.
Among the public guidance available, Proficiency Enhancements are the closest thing to an always-take upgrade. The reason is simple: they improve your starting Proficiency on new runs, which means your baseline damage floor is better before a run has even stabilized. In a game built around repeated attempts and permanent progression, that kind of upgrade does more work than a narrow defensive bonus.
Proficiency also appears to help both standard weapon output and Power Weapon effectiveness, so it is not just a niche stat for one loadout. If your early runs feel weak, this is the branch that usually fixes that fastest. Even when a build later shifts toward shielding, healing, or specific weapon synergies, better early damage makes the whole route cleaner because enemies die before mistakes stack up.
There is one extra reason some players rate Proficiency even higher: at least one video summary claims that after the first boss, each Proficiency level may also feed broader stat growth such as Resilience, Command, and Drive. That detail is not as well corroborated as the rest of the advice, so it is better to treat it as a possible bonus rather than the core reason to buy Proficiency. Even without that interaction, it is still one of the best first picks in the tree.
If Proficiency is your damage engine, Drive is your account-growth engine. Public writeups are especially clear here: Drive increases Lucenite income from drops and exploration, which means every future upgrade becomes easier to afford. That makes Drive stronger than it first looks, because it is not just a stat on the current run. It accelerates your entire progression curve.

This is why most early advice says to choose Drive first when the tree forces a choice between Drive, Command, and Resilience. Command and Resilience both matter, but Drive compounds. More Lucenite means more Armor Matrix upgrades, more flexibility in later routes, and faster access to the branches you actually want. In practice, that compounding effect is what makes Drive feel better than another small survivability bump.
When you hit one of the early orange nodes or any similarly high-value branch point, do not spend it just because it is available. Spend it to reach Drive faster if the alternative is a flatter stat with no snowball effect. That is the routing choice that most often separates a smooth early profile from a sluggish one.
Once Aether upgrades are available, they move up the list quickly. The available guidance indicates this branch is gated until after defeating Bastion, the second boss. That exact unlock point is worth treating as moderate confidence rather than absolute fact until you confirm it in your own file, but the broad takeaway is solid: Aether is not your first priority at the start, yet it becomes one of the best pickups once the tree opens.

The reason is survivability. Extra Aether drops and stronger healing let you extend attempts that would otherwise collapse from chip damage, especially when boss nodes or higher-pressure routes start demanding cleaner play for longer stretches. If Proficiency gets you ahead and Drive helps you grow faster, Aether is what prevents a strong run from dying before it pays out.
Restoration is the natural partner stat here. More healing resources are good, but more value from each heal is what makes sustain really efficient. If you are already dying late in runs rather than early, this is usually the point where Restoration starts outperforming another small damage or health bump.

Delaying Command and Resilience does not mean they are bad. The current consensus is more about timing than value. Command appears tied to Power Weapons and shields, while Resilience is your direct health line. Those are both useful stats, especially if you prefer safer play or a loadout that leans hard on ability usage.
They simply do not give the same early return as Proficiency or Drive. A small health increase does not accelerate your future unlocks. A Command pickup only becomes a top-tier choice once your build already depends on the tools it enhances. Until then, the smarter progression route is usually to secure the universal benefits first and only then specialize.

The main exception is if you are consistently losing runs to single mistakes rather than attrition. In that case, one early Resilience detour can be justified. It just should not replace the overall priority stack.
The best advice is not to grab nodes blindly. Plan the route around the branch rewards you are trying to reach. In practical terms, that means checking what each unlocked section of the skill tree actually leads into before you spend your Lucenite. A cheap filler node is only worth it if it opens a path toward Proficiency, Drive, or your first post-Bastion Aether picks.
There is also a useful optimization note around weapon scaling. One public video breakdown points out that the directional indicators or arrows beside weapon scaling bars can matter more than the raw headline number. In other words, a bigger number is not always the better long-term pick. If a skill node changes how your weapons scale, check the actual scaling behavior instead of assuming the largest visible stat is best.
The clean early-game plan for Sorrow’s Serenade is to build offense with Proficiency, accelerate future unlocks with Drive, then stabilize longer runs with Aether and Restoration once that branch opens. If a node does not help one of those three jobs, it is usually not your best first purchase.
