Efficient Material Farming in Honkai: Star Rail: Calyx, Stagnant Shadow, Echo of War, and a Weekly Route
30-second summary: Efficient farming means spending all 240 Trailblaze Power each day in the right place, plus milking free no-energy sources like Assignments. Calyxes (10 energy) give EXP, Credits and Trace materials; Stagnant Shadows (30 energy) give character ascension materials; Echoes of War (30 energy, only 3 rewarded clears per week, resets Monday) give advanced Trace materials; Relics come from Caverns of Corrosion (40 energy, the 4-piece set) and Simulated Universe (the 2-piece Planar Ornaments). Trailblaze Power refills 1 point every 6 minutes (240 a day to spend), the wallet caps at 300, and anything above that auto-saves into a Reserved pool up to 2,400, so nothing is lost. Route: clear your 3 Echoes of War early each week, put the rest into leveling and ascension, and only grind Relics once your team is solid.
Trailblaze Power: your 240-a-day energy budget
In Honkai: Star Rail almost every meaningful upgrade material is bought with an energy called Trailblaze Power. Think of it as a daily allowance in a wallet that stops filling once full. The wallet holds up to 300 points, and it refills 1 point every 6 minutes — exactly 240 over a full day, which is your daily budget. Because it caps at 300, energy you don't spend for more than a day eventually overflows. It isn't wasted, though: overflow pours into a separate pool, Reserved Trailblaze Power, which stores up to 2,400 points and refills slower, 1 point per 18 minutes. You withdraw from it 1-to-1, up to 300 at a time. The takeaway is simple: try to spend close to 240 every day, and don't leave the wallet capped for long. To see exactly what a character needs — EXP books, ascension items and Trace materials — open GameVika's Materials tool (/hsr/materials); it lists every quantity so you farm on purpose, not by guesswork.
Main pool: 3001 point per 6 min = 240 a day Reserve: 2400Overflow pours in, 1 point per 18 min Calyxes: the cheapest farm for EXP, Credits and Traces
Calyxes are the cheapest farm: just 10 Trailblaze Power per run. There are two kinds. Golden Calyxes drop leveling materials, character EXP, Light Cone EXP, and Credits (the game's money). Crimson Calyxes drop Trace materials, used to unlock and raise a character's passive skill tree. Since a run is only 10 energy, you can stack multiple waves in one go: each extra wave adds 10 energy, up to 240 in a single press. With Fuel you can quick-farm, spending 1 Fuel per 10 energy so you skip the fighting. Small note: Calyx enemies get +70% HP but -20% ATK, so even a weak team clears them, just a bit slowly. Don't grind blindly: use GameVika's Items tool (/hsr/items) to see exactly which Calyx drops the material you're short on, then farm only that one.

Crimson CalyxTrace upgrade materials (skills) Stagnant Shadows: character ascension materials
Stagnant Shadows are where you get Ascension materials, the items that raise a character's level cap past locked breakpoints (20, 30, 40 and so on). Each run costs 30 Trailblaze Power, three times a Calyx, so farm with intent. A win gives 2 to 5 items depending on the difficulty you pick; higher difficulty drops more, so once your team is strong enough, always take the highest tier you can clear. You can fight up to 8 in a row manually; with Fuel quick-farming, each run eats 3 Fuel and you can sweep up to 10. Enemies here get +40% HP with no ATK reduction, so you need real damage. Since each character needs a specific ascension material, don't guess: open GameVika's Materials tool (/hsr/materials) to see which Shadow your character needs, then farm that exact map. Farming the wrong one wastes a whole session of energy.
Echoes of War: advanced Trace materials, 3 rewarded runs a week
Echoes of War are rematches against story bosses, and the source of advanced Trace materials, the ones needed to push skills to level 8+ and unlock Bonus Abilities. This is the weekly-limited part, unlike the daily Calyx and Shadow. Each attempt costs 30 Trailblaze Power, but you can only claim rewards from 3 attempts per week (you can keep fighting, just with no loot). The reward count refreshes Monday at 4:00 AM server time. Alongside the main material, each clear also gives some Relics, Credits and free 4-star Light Cones. Because you only get 3 rewarded runs a week, never skip them: clear all 3 every week, prioritizing the boss that drops materials for whoever you're leveling. Not sure which boss drops what you need? GameVika's Materials tool (/hsr/materials) tells you instantly.
Caverns and Simulated Universe: farming Relics for the long game
One more source worth knowing for weekly planning: the Cavern of Corrosion, where you farm Relics, the gear that adds stats to characters. Each run costs 40 Trailblaze Power, the priciest of the group. It can't be quick-farmed with Fuel; you fight manually, but you can stack up to 6 runs at once (240 energy total). The upside: at a high enough difficulty a 5-star Relic is nearly guaranteed, sometimes two at a time. But remember: a full Relic set has two halves. The four main pieces (Head, Hands, Body, Feet) drop in the Cavern of Corrosion. The other two — called Planar Ornaments (a Planar Sphere and a Link Rope) — do NOT drop here; you can only farm them in Simulated Universe and Divergent Universe. The Planar reward uses a separate ticket called an Immersifier, which refills on its own so it doesn't touch your 240 Trailblaze Power; when you're out of Immersifiers, you can pay 40 Trailblaze Power per reward instead. To assemble a strong set you need both halves. Because Relics are a stat lottery, same piece with random sub-stats, this is usually where energy disappears once a character is fully leveled. Advice: early on, prioritize Calyxes and Shadows to get a team leveled and ascended so it actually functions; only once the team is solid should you pour long-term energy into Caverns (the 4-piece set) and Simulated Universe (the 2 Planar Ornaments) to polish Relics. Relic farming is a marathon, not a sprint.
A weekly farming route for busy players
Put it together into a route for busy players: each day you have 240 Trailblaze Power, plus 3 weekly Echo of War runs. A clean split: (1) Early in the week, spend 90 energy clearing all 3 Echoes of War first, since that's the capped part, miss it and it's gone for the week. (2) While leveling a new character, pour most remaining energy into Calyxes (EXP + Traces) and Shadows (ascension) until they're battle-ready. (3) Once the team is solid, shift daily energy to Caverns of Corrosion (the 4-piece set) and Simulated Universe (the 2 Planar Ornaments) for Relics. (4) Going away for a few days? Let energy overflow into the 2,400 Reserved pool and collect it later, nothing is lost. And don't forget the FREE, no-energy source: Assignments (Dispatch) — send characters out on tasks for Credits, EXP books, ascension gems and synthesis materials; just collect and re-send every day or two, and it never costs a single Trailblaze Power. Don't burn Stellar 
Jade to buy energy; save Jade for pulling characters. To check how much Jade you have and who you can afford, use GameVika's Jade Planner (/hsr/jade-planner). And before each new build project, open the Materials tool (/hsr/materials) so you know the totals and farm on target.

Overworld enemy runs: a daily resource mine that costs no Trailblaze Power
Here is a resource many newcomers overlook: the enemies roaming the maps you have already unlocked. Every time the server refreshes for the day, these enemies respawn in full, and clearing them costs ZERO Trailblaze Power — only a little of your time. It is a reward for your footwork, completely separate from your 240-energy daily budget.
The easiest method: pick an area whose layout you know well and plan a loop that runs past the densest enemy clusters. Before each fight, use your character's overworld Technique to ambush them — you enter combat with an edge, and many units even deal Toughness (Break) damage up front. Once in battle, break the weakness fast and scoop up the drops.
You do not need a strong team. Free characters like the Trailblazer, 
March 7th, 
Dan Heng, 
Natasha or 
Asta clear these easily. Do it while running your daily missions to save time. And if a Sequence Trotter suddenly jumps into a fight, try to kill it before it flees for some bonus loot.

What overworld farming gives you, and when to prioritize it
Clearing overworld enemies returns three things steadily. First, character EXP materials — the books you use to level characters up. Second, Credits, the currency you are always short on while leveling and upgrading Relics at the same time. Third, common Trace materials tied to each enemy family — exactly the items you need to raise a character's skills; lower tiers can be synthesized into higher ones at the Omni-Synthesizer.
When should you prioritize this? While you are early-to-mid game, or short on Credits and Trace materials, and you have already spent your Trailblaze Power for the day — that is when a map sweep 'earns extra' without waiting for energy to refill. Whenever a new area opens, do one clearing run: each area usually hides a single Warp Trotter that drops Stellar Jade, but only once, so do not miss it.
Not sure which Trace materials your characters still need? Open the character lookup tool on GameVika to see the exact list before you set out to farm.

How much Trailblaze Power do I get per day?
The Trailblaze Power wallet caps at 300 and refills 1 point every 6 minutes, so a full day gives you exactly 240 to spend. Overflow drains into the Reserved pool (up to 2,400, 1 point per 18 minutes) so it isn't lost, but spending daily is best.
Should I farm Calyxes or Stagnant Shadows first?
When building a new character, feed both in parallel: Calyxes for EXP and Trace materials, Stagnant Shadows for the ascension materials that break level caps. Missing ascension mats hard-locks the level; missing EXP just slows it, both block progress, so split energy until the character is battle-ready. Use /hsr/materials to see the amounts.
How many times a week can I run Echo of War?
You can enter an Echo of War as often as you like, but you can only claim rewards from 3 runs per week, each costing 30 Trailblaze Power. The reward count resets Monday at 4:00 AM server time. Those 3 clears give the advanced Trace materials for level-8+ skills, so clear all 3 every week.
If Trailblaze Power overflows past 300, is it lost?
No. Once the 300 wallet is full, further regen flows into Reserved Trailblaze Power, which holds up to 2,400 (refilling slower, 1 per 18 minutes). You withdraw it 1-to-1, up to 300 at a time. So a few days away won't waste energy, just don't leave the Reserved pool capped for too long either.
