Booster Pack Heroes Best Relics: The Short Answer
A strong relic can turn a messy pack opening into a run that actually reaches the next boss. That is why the Booster Pack Heroes best relics matter more than raw rarity: an effect that duplicates units or stops leaks often beats a flashy damage trinket that never activates. If you are comparing Booster Pack Heroes best relics, judge them by what they do in the next three waves, not by how good they look in a vacuum.
Booster Pack Heroes is an incremental game built around opening booster packs, upgrading heroes, and surviving waves. Relics are the modifiers that shape those packs and battles. Because offers are random, the goal is not to force one perfect item; it is to recognize the strongest effect for your current hero pool, economy, and boss timer.
The Booster Pack Heroes best relics usually fall into five buckets: unit duplication, rarity improvement, elemental damage, defensive coverage, and economy or slot access. A relic that only boosts a tag you do not own is not a “best” pick in that run, even if its effect looks powerful on paper.
| Relic effect | What it does | Best time to take | Priority |
|---|---|---|---|
| Warrior appearance and duplication | Warriors are more likely to appear, and the first two warriors that spawn are duplicated | Early warrior-heavy run | High if you already have warriors |
| Rare hero appearance boost | Raises the chance that rare heroes appear | Early or mid game when your collection is thin | High |
| Chain lightning / electrify | Gives attacks a chance to electrify and chain lightning | Mid game with many attackers | High |
| Hunter appearance boost | Makes hunters more likely to appear | Only when your pack pool supports hunters | Situational |
| Mystic revive | Mystic heroes that spawn can gain revive | Mid or late game with mystics | High for mystic builds |
| All-hero block chance | Gives every hero block chance | Any defensive phase | High |
| Discount | Reduces shop costs | After your board can survive | Medium |
| Additional relic slot | Expands how many relics you can equip | Whenever offered, especially before a boss | Very high |
| Thunderbolt damage | Increases thunderbolt damage | Only in a lightning or thunder-focused build | Medium or situational |
How to Judge Booster Pack Heroes Best Relics Before Equipping
A relic’s value changes with timing. Early in a run, you need bodies on the field and enough gold to keep buying packs. Later, you need effects that stop a boss from chewing through your tower. The same relic can be a snap pick in one stage and a wasted slot in another.
Use four questions before you equip anything:
- Does it add or duplicate units now? Effects that create extra warriors or improve spawn counts have immediate board impact.
- Does it match your actual hero pool? Warrior, hunter, and mystic boosts are only as good as the units you own.
- Does it solve the next fight? A defensive relic before a boss is often worth more than a small economy gain.
- Does it compound? Additional relic slots and broad effects like block chance improve every later choice.
| Run phase | Main goal | Relics to favor | Relics to avoid |
|---|---|---|---|
| Early act | Build a board and start scaling | Warrior duplication, rare hero boost, cheap discount | Narrow thunderbolt or hunter boosts with no support |
| Mid act | Stabilize against larger waves | Chain lightning, block chance, mystic revive | Pure economy when the tower is already leaking |
| Boss wave | Survive burst and finish the fight | Block chance, additional relic slot, revive, chain lightning | Greedy discount if you need defense immediately |
| Post-boss cleanup | Fill remaining slots | Flexible defense, slot access, broad damage procs | Tribe boosts for units you are not buying |
The strongest relic is not always the rarest one. A common-looking block chance relic can carry a boss fight because it applies to every hero. A rare damage relic can sit dead if your pack strategy never produces the right attackers. Treat relic choice as a deck-building decision, not a collector’s checklist.
Booster Pack Heroes Best Relics by Build
Build direction matters more than a flat ranking. The Booster Pack Heroes best relics for a warrior swarm are not the same as the best picks for a mystic setup or a lightning-heavy board. Use the table below as a starting point, then adjust based on what your packs actually deliver.
| Build | Relic priorities | How to play it | Avoid |
|---|---|---|---|
| Warrior swarm | Warrior appearance and duplication, block chance, discount | Buy warrior packs early, let duplicated warriors form a front line, then add defense | Hunter or mystic boosts with no matching units |
| Rare high-roll | Rare hero appearance, chain lightning, block chance | Improve rarity before opening key packs, then let rare heroes trigger lightning effects | Spending early slots on economy when you need bodies |
| Lightning and attack frequency | Chain lightning / electrify, thunderbolt damage, block chance | Pair lightning effects with many attackers so proc chances occur often | Thunderbolt boosts when you have no thunder source |
| Mystic sustain | Mystic revive, block chance, additional relic slot | Keep mystics alive through long fights and let revive stretch their value | Warrior duplication when your pool has no warriors |
| Defensive tower | Block chance, revive, additional relic slot | Take one defensive relic before every boss and fill flex slots with survival effects | All-in economy builds that ignore tower health |
Warrior duplication is especially strong when it arrives early. It does not just add a body; it multiplies the first two warriors that spawn, which can stabilize your front line before the first serious wave. If the same relic also raises warrior appearance, commit to warrior packs and stop splitting your relic slots across unrelated tags.
Rare hero boosts are a different kind of value. They improve the quality of future packs rather than the current board, so they are best taken before you spend a large batch of gold. If you take a rare boost after you have already opened most of your packs, you get less return. Pair it with a broad combat relic so the run does not stall while you wait for the payoff.
Lightning effects reward volume. Chain lightning and electrify need attacks to trigger, so they fit boards with many heroes attacking often. Thunderbolt damage is narrower; take it when your run already leans into thunder damage. Do not fill a slot with a damage-type boost and then wonder why your basic warriors are still the only thing hitting the boss.
Mystic revive is a sustain effect, not a burst effect. It shines when mystics are a real part of your board and fights last long enough for revival to matter. In short fights, block chance or raw duplication will usually do more. In long boss fights, revive can be the difference between a lost tower and a completed chapter.
Relic Slot and Economy Decisions
Relic slots are limited, and every slot competes with another effect. That makes “additional relic slot” one of the most valuable effects in the game: it does not just give one stat, it lets you combine more of the effects your build needs. When a slot expansion is available, take it unless you are about to lose the run without an immediate defensive pickup.
| Decision question | Take it? | Reason |
|---|---|---|
| Does it add or duplicate units right now? | Yes | Immediate tempo and safer early waves |
| Does it boost a tag you actually own? | Yes | Synergy beats raw rarity |
| Does it only save gold? | Delay | Discount needs time to pay off and does not stop leaks |
| Does it raise block chance or revive? | Usually yes | Broad defense covers boss mistakes |
| Does it boost a damage type you already use? | Yes | Scaling is real when the trigger exists |
| Does it open another relic slot? | Yes | More slots compound every later relic choice |
| Does it require a tribe absent from your packs? | No | A dead slot is worse than a small generic bonus |
A common trap is taking discount too early. Cheaper purchases feel great, but a discount relic does nothing when the tower is already taking damage and you need bodies immediately. Take discount after you have a stable board, or take it before a planned shopping spree when you know you can survive the next wave.
Another trap is overvaluing narrow tribe boosts. Hunter appearance is excellent if you are buying hunter packs and have hunter support. It is close to useless if your board is mostly warriors and mystics. Before equipping any tribe-specific relic, check your current units and your next pack target. If both point in the same direction, the relic is strong. If not, keep the slot open for a broad effect.
Boss Fights: Which Relics Actually Help
Boss waves punish greedy builds. The Iron Legion and foil bosses can absorb damage, spawn extra threats, and outlast a board that was only built to clear normal waves. A run that looks healthy during trash waves can collapse when the boss arrives and your relic slots are filled with economy effects.
| Boss problem | Relic answer | Why it helps |
|---|---|---|
| Trash leaks past your front line | Chain lightning / electrify, block chance | Clears groups and softens leaks before they reach the tower |
| Boss outlasts your damage | Warrior duplication, thunderbolt damage if supported | Adds scaling or improves a damage type you already use |
| Heroes die before they contribute | Block chance, mystic revive | Extends hero uptime during long fights |
| Tower takes chip damage | Block chance, defensive relic first | Prevents a slow loss while your damage comes online |
| You lack slots for the right answer | Additional relic slot | Gives flexibility for both offense and defense |
| You cannot afford upgrades before the boss | Discount earlier, not during the fight | Economy relics need time to generate value |
For boss preparation, the safest pattern is one broad defensive relic plus one scaling relic. Block chance covers every hero, so it is rarely wasted. Duplication or chain lightning gives you a way to actually finish the boss instead of merely surviving longer. If you have a third slot, add revive for mystics or thunderbolt damage for a lightning build.
Foil bosses raise the stakes because they are tougher versions of an already dangerous fight. Do not assume a relic that cleared the previous chapter will carry the next one. If your damage is single-target and the boss brings extra units, chain lightning or a wider damage proc can be more useful than another small stat boost.
FAQ
What are the Booster Pack Heroes best relics for beginners?
Start with effects that add or duplicate units, improve rare hero appearance, or give all heroes block chance. These are easy to understand and work across many builds. Add chain lightning when you have enough attackers, and delay discount until your board can survive without immediate help.
Should I always take a discount relic?
No. Discount is a strong economy effect, but it does not defend the tower or add units. Take it after you have a stable board, or when you are about to buy several packs and can afford to wait for the savings to matter.
Are tribe-specific relics worth it?
Only when your hero pool matches the tribe. Warrior duplication is excellent in a warrior run, hunter appearance is strong in a hunter run, and mystic revive is valuable when mystics are already on the board. A tribe relic with no matching units wastes a slot.
How do I get more relic packs?
Relic packs come from chapter progress, bosses, and quest rewards. If a relic pack reward does not appear, update the game and check the current patch notes before assuming the run is bugged; relic reward fixes have been part of post-launch updates.
