You beat the original. The sequel threw five characters, a Timeline full of Epochs, Ancients instead of boss relics, and a pile of new keywords at you all at once. This guide untangles it — starting with the one screen that decides every run: the map.
One act, bottom to top. The dotted gold line is a healthy route: early fights for gold and cards, one elite for a relic, a merchant, and a campfire right before the boss.
Your STS1 instincts are 80% right. These are the systems that replaced ones you knew — map them once and the noise drops away.
The unlock chain is a deliberate difficulty curve: one finished run with each character unlocks the next. Play them in this order and each mechanic settles before the next layer arrives.
Still the forgiving on-ramp. Strength stacking and self-damage payoffs are stronger than ever, with refreshed Exhaust synergies. The healing relic quietly undoes small blocking mistakes — perfect while you relearn the game.
Her big new toy is Sly: Sly cards auto-play when discarded, turning discard engines into free value. Poison still wins long fights; shivs still shred with Accuracy. Higher ceiling, squishier floor.
Manages Stars as a second resource alongside energy, and uses Forge to transform cards and scale the Sovereign Blade. Your first taste of STS2's dual-resource decks — punishes sloppy sequencing, rewards planning.
Fights by proxy through Osty, who attacks and tanks for her. Doom executes enemies when it ripens; Soul tokens fuel graveyard loops where you spend HP for enormous turns. The most mechanically dense character in the franchise.
Channel, Evoke, and Focus all work the way you remember, plus the new Glass orb — a decaying area-damage orb that rewards ending fights fast. Layered on last because orb economy sits on top of everything else you've learned.
Every unfamiliar term you'll hit in your first ten runs, in one place.
A Sly card plays itself automatically when discarded. Discard engines stop being card disadvantage and start being a second hand.
A ticking execution mechanic — stack it on enemies and finish them when it triggers, skipping their remaining HP bar.
Tokens cycled through her graveyard loops; the fuel for her biggest, riskiest turns.
A second currency spent alongside energy. Budget both every turn — running dry on either stalls the deck.
Transforms and upgrades cards mid-run to scale the Sovereign Blade. Deck sculpting as a win condition.
A new orb dealing decaying damage to all enemies — strongest the turn you get it. Rewards aggression, not incubation.
Gradually melts your maximum HP during combat. The anti-turtle mechanic — long fights get more expensive the longer they run.
Damage that goes through block. Against Pierce enemies, killing fast beats blocking perfectly.
Some relics burn out temporarily after several activations per combat. Situational power spikes replaced infinite passive value.
Trade-off modifiers that attach to cards — more damage for max HP, Vulnerable application that drains energy. Every one is a bargain; read the fine print.
Milestone nodes on the Timeline that unlock cards, relics, potions, characters, and lore. Claim them manually from the main menu.
Blessing-granting NPCs at each act's start, replacing boss relics. Neow opens every run; each later act draws from its own Ancient pool.
The decision rules that separate a run that dies in Act 1 from one that sees the top. Most are STS1 wisdom — sharpened for a sequel that punishes hesitation.
Before your first step, look at the boss icon at the top of the act and bend every path decision toward surviving that specific fight. Heavy hitter? Stack defense on the way. Punishes big attack turns? Draft block and passive damage.
The single biggest new-player leak: adding a card after every fight. A 40-card deck can't find its block card when a boss winds up for 45. Every pick should serve a win condition — skipping is a strategic choice, not a wasted reward.
The merchant's card removal is worth more than almost anything on the shelf. Cutting Strikes and Defends is how synergy pieces actually show up in your hand. Note: on Ascension 6+, removal costs climb with each purchase, so remove early.
Every elite drops a relic, and relics compound across the whole run. Rest at a campfire before the fight, take it while healthy, and treat the new Act 1 elites with respect: they front-load damage harder than anything in the original.
Potions are stronger than in STS1 and you'll keep finding more. A full potion belt at a boss is fine; a full belt for three floors while skipping drops is waste. Spend them on elites without guilt.
Strikes clear Act 1 hallways; they do not clear act bosses. Every deck needs a scaling engine — Strength, poison, orbs, Doom, a forged blade — and every draft should feed it. Damage first, then defense, then draw to find both.
Runs that die still push the Timeline forward. Go in with a goal — learn one boss pattern, test one archetype, unlock one Epoch — and the loss is tuition, not failure. This game is built on that loop.
The post-combat reward screen, as a reflex. Run this in your head every single time.
Draw consistency is the invisible stat. Protect it.
A plan turns losses into progress. Here's the on-ramp.
Goal: reach the Act 1 boss and learn the new elite patterns (the Statue and the Phrog front-load damage — block turn one, don't greed). Draft simple: damage first, one or two block cards, remove Strikes at every shop.
Before starting, open Timeline from the main menu and claim every Epoch you've earned — rewards do not apply automatically. New cards, relics, and your Silent unlock are sitting there waiting.
Pick one archetype per run — poison one run, Sly discard the next — instead of mixing. Notice how much squishier she is: pathing around damage matters more than it did on Ironclad.
Budget Stars like a second energy bar. When a turn goes wrong, ask which resource you wasted. This is the skill the rest of the roster is built on.
Let Osty tank, experiment with Doom executes, and expect to lose — she's the deepest character in the game and that's the fun of it.
With all five unlocked and a fat stack of Epochs claimed, pick your favorite and start climbing Ascensions (1–10 in Early Access). Now the Ancients guide, boss-specific tech, and archetype mastery are your rabbit holes.
STS1 rewarded patient, defensive mastery. STS2's Corrosion, Pierce, and burnout relics all whisper the same thing: adapt aggressively, kill decisively, and treat every blessing, enchantment, and relic as a situational bargain — not a permanent stat stick. The players thriving right now are the ones re-reading everything instead of autopiloting on 2019 instincts.
