The first island in How to Fish presents players with a significant challenge in the form of the Spider Crab boss. While the game's title suggests a focus on fishing, overcoming this initial hurdle requires a different set of skills, primarily combat prowess.
To prepare for this encounter, players should prioritize completing the tutorial quest offered by the sailor. Beyond the tutorial, a few key purchases and actions can significantly ease the path to victory. It is recommended to first purchase clams, costing approximately $3 each, and feed them to the sailor instead of his beer. Following this, the Fishing Rod, priced at $3, should be acquired. Subsequent purchases of clams or using the rod to catch fish for more profitable meals are advisable. The next crucial step involves buying either a Knife for $45 or Brass Knuckles for $24, as a melee weapon is highly recommended for the solo player experience. Once a weapon is secured, the Beer for $12 can be purchased and given to the sailor, who will then crush the empty can. This empty can is to be used as bait to lure the Spider Crab boss.
Direct combat with the Spider Crab can be punishing; its quick claw attacks can incapacitate a player in just three to four hits. Healing can be achieved by consuming clams or fish caught during the game. A key strategy during the fight involves exploiting the boss's dazed state after it attacks. Players should use these brief openings to land hits. Patience is vital, as even on easier difficulties, the fight often involves a cycle of attacking the immobilized crab and retreating to safety.
Leveraging the game's physics and terrain is also important. Standing on higher ground can make it more difficult for the Spider Crab to reach the player, facilitating evasion of its attacks. While the boss can be manageable in co-op using only fists, the added damage from a melee weapon like the knife is a significant advantage in solo play.
Upon defeating the Spider Crab, players should collect its remains and deliver them to the old fisherman. This action rewards the player with the keys to his boat, allowing progression to the next island. Before departing the initial island, purchasing the radar for $10 is also a recommended step.
