What Makes Soul Fysh Dangerous?
Soul Fysh poses a unique challenge because its lethality comes from accumulation rather than a single devastating blow. The primary hazard is the Beckon status card, which functions as a ticking time bomb within your deck. Every Beckon card requires one Energy point to either exhaust or discard before your action phase concludes. If you end your turn holding this card without managing it, the boss inflicts six points of unblockable damage automatically. This means standard defensive strategies relying on block values become irrelevant if you cannot clear the status cards from your possession.
The enemy distributes these Beckon tokens across both your draw pile and your discard pile simultaneously. Consequently, they will surface in your hand at irregular intervals throughout the battle. Players must maintain a delicate balance between generating offense and clearing their hand of these liabilities. Failure to prioritize Beckon removal leads to rapid health loss regardless of how well you prepared defensively. Managing this resource drain effectively is the fundamental skill required to survive this engagement.

How Does the Soul Fysh Attack Pattern Work?
This adversary operates on a predictable five-turn cycle that players should memorize immediately. Understanding this rhythm allows you to optimize when to push damage versus when to conserve resources. During the opening turn, the boss plants one Beckon in each pile without attacking. This is your chance to deal early damage while preparing to exhaust any Beckons that appear. Next, the enemy unleashes a heavy attack exceeding fifteen damage. You should maximize offense here while blocking what you can, treating this as a prime opportunity to reduce boss health significantly.
On the third turn, incoming damage falls below ten, but another Beckon enters your draw pile. Since the threat is lower, you should capitalize on your accumulated resources to deal damage. Be wary, however, as the fight escalates quickly; early manageable hits become dangerous later due to potential health pool erosion. Turn four presents the most critical trap, as the boss gains Intangible, reducing all player damage to one per hit. You must unload your biggest attacks before this buff activates. Finally, turn five maintains Intangible while applying three stacks of Vulnerable. At this stage, shift entirely to survival mode, focusing on blocking and discarding Beckons until the next cycle begins.
What Changes in the Second Rotation?
Completing the initial five-turn sequence triggers a significant escalation in difficulty for the second rotation. The three stacks of Vulnerable applied at the end of the first cycle remain active starting from the beginning of the second. This debuff increases all damage you receive by fifty percent, transforming previously safe hits into severe threats. Under these conditions, attempting to trade hits is no longer a viable strategy. Your approach must pivot toward consistent blocking and rapidly discarding Beckon cards to prevent fatal error.
Your objective shifts to securing a victory before the cumulative damage becomes unsustainable. If you entered the second rotation with the boss still possessing over half of its total health, the encounter becomes exponentially more difficult. Therefore, maximizing damage output during the strongest offensive turns of the first cycle is essential. You want to enter the vulnerable phase with the boss sufficiently weakened that you can secure a quick knockout. Prioritizing high-value turns ensures you do not get bogged down in a prolonged battle where every attack punishes you heavily.

What Cards Work Best Against Soul Fysh?
Selecting the right deck composition before entering the Underdocks final fight is crucial for success. Certain card types offer superior utility against the Beckon mechanic compared to others. Acrobatics provides a reliable method to cycle cards out of your hand while drawing new ones, helping to manage Beckon loads without spending energy. Burning Pact is equally valuable since it exhausts a card while drawing two, allowing you to permanently remove Beckons and refresh your options. Regent's Reflect offers a unique advantage by converting block into damage, enabling you to contribute offensively even on defensive turns.
Additionally, maintaining a deck with low energy cost attacks is vital. A lean deck ensures that encountering a Beckon does not paralyze your entire turn, leaving you unable to act. Cards capable of exhausting status cards are generally preferred over those that merely discard them. Once a card is exhausted, it is removed from the game permanently, eliminating the risk of it returning to your hand later in the fight. This permanent removal creates a cleaner path to victory compared to standard discard mechanics.
Key Tips for Beating Soul Fysh
Successful execution relies on respecting the patterns established by the boss throughout the encounter. Never leave a Beckon in your hand unless you are certain the resulting six damage will not jeopardize your survival. Treat the second and fourth turns of the cycle as your primary windows for dealing maximum damage. The second turn offers straightforward aggression, while the fourth requires you to attack before the Intangible buff negates your power. Building your Act One deck around Energy efficiency is also key. Having extra energy points grants flexibility to handle Beckons without sacrificing your ability to attack.
Once the Vulnerable debuff lands in the second rotation, adopt a defensive mindset. Blocking incoming damage takes precedence over offense to ensure longevity. This patience keeps you alive long enough to land the final blow. Ultimately, this fight rewards careful observation and disciplined play. After observing the five-turn cycle a few times, the battle transitions from improvisation to precise execution. Following these guidelines ensures you can navigate the mechanics reliably and claim victory against Soul Fysh.
