Energy is the tightest bottleneck in RAID: Shadow Legends — it decides how many dungeon, campaign and boss runs you get through in a day. The good news is that there are more sources than most players use, and most "energy problems" are really spending problems. Below: where energy comes from, what content actually costs, and how to stop leaking the bar.
Every energy source that matters
Regeneration is the base; everything else just speeds it up. Order matters — take the free stuff first and spend gems last.
- Regeneration. Roughly 1 energy every 5 minutes, so about 12 per hour. It ticks constantly until the bar hits your cap.
- The cap. It grows with account level: a few dozen at the start, around 130 at high levels.
- Account level-ups. Levelling up refills the bar completely. It is a free refill that most players forget to plan around.
- Daily quests. The chest for completing all dailies contains energy — your most reliable source after regen.
- Weekly and monthly quests. Bigger chunks, same idea.
- Login rewards. Daily logins hand out energy from time to time.
- Events, tournaments and CvC. Energy regularly sits in personal and clan milestone rewards; don't skip the mid-tier milestones.
- Gems. The standard refill costs 40 gems and fills the bar.
- One-off rewards. Campaign progress, first clears, event milestones.
What content actually costs
| Content | Energy per run | Note |
|---|---|---|
| Campaign | 4–10 | Depends on difficulty: higher difficulty costs more per run but pays better |
| Dungeons (Dragon, Spider, Fire Knight, Ice Golem, Keeps) | About 8 on low stages, 16–20 on high stages | Loot per energy improves with stage |
| Minotaur (masteries) | Same as a normal dungeon | The real cost is the number of runs, not the run itself |
| Arena | 0 | Tokens, not energy |
| Clan Boss | 0 | Keys |
| Hydra | 0 | Its own keys |
The cap and overflow: where the real losses are
Regeneration stops the moment the bar is full. Spending a whole day with a full bar means losing well over two hundred energy that nobody gives back. That leads to the main rule: log off with a half-empty bar, not a full one.
Energy from rewards can usually go above the cap and doesn't burn — but regeneration is paused while it sits there. Holding a permanent overflow is a bad deal: you pay in idle regen for a nice-looking reserve.
Account levels deserve their own note. If you are close to the next level, drain your energy to zero first and only then finish the XP. The level-up will fill the bar completely instead of topping up an already full one.
Gem refills: when they are worth it
40 gems for a full bar is an honest trade only when three conditions line up at once.
- Empty bar. The refill fills it to maximum, so buying one at half a tank means throwing half of it away.
- A concrete goal. Masteries through Minotaur, farming a specific set, closing out a tournament milestone.
- An event. A refill during a tournament or x2 pays twice: you get the runs and the tournament points.
If there is no goal, hold the gems. Shards and books eat a lot of them, while "just in case" energy disappears into a random dungeon.
Where energy gets wasted
- Farming low dungeon stages when higher ones are open: noticeably worse loot per energy.
- Levelling champions in campaign on a low difficulty while a higher one is unlocked.
- Running content you cannot clear reliably: a wipe is minus energy and minus time.
- Endless team swapping "for luck" instead of one thought-through run.
- Ignoring free modes: Arena, Clan Boss and Hydra cost no energy but pay out resources every day.
Six rules that save your bar
- One goal per session: either masteries, or gear, or campaign — not all at once.
- Before logging off, drain the bar below the cap so regen keeps ticking.
- Plan farming around a tournament or event so the same runs also earn points.
- Push your stage progress: the higher the dungeon stage, the better the return for the same energy.
- Don't buy a refill with an almost-full bar.
- Clear the free stuff first — dailies, Arena, Clan Boss — and spend energy after that.
Summary
Energy in RAID is not really about "not getting enough" — it is about where it goes. Keep the bar below the cap, collect the free sources (dailies, weeklies, events, account levels), buy refills only for a specific goal and stop farming low stages while higher ones are open. That alone gets you noticeably more runs per day without spending a single gem.
