Heavyweight Fishing Gameplay and Strategy
The game says it was inspired by a fishing game called "Chu Xin Diao". Every fish is a fight: you cast, then work the catch bar to land it. Bigger fish and bosses need a stronger rod, so most of your cash goes into gear.
The Heavenpiercer Rod and the Pure Diamond Rod are seen as the best right now, and the Cryo Gravity Rod is a good pick for making cash in the middle of the game.
Skills come from two summon banners called Taiji and Egoless. A rare skill is guaranteed at 30, 120 and 1,000 summons. Traits are rolled with Trait Rerolls, which several codes also give out.
Heavyweight Fishing Traits
There are 13 traits. Here is each one with its chance on a reroll, from rarest to most common.
| Trait | Chance |
|---|---|
| Vermillion Bird | 0.1% |
| White Tiger | 0.1% |

| Precision | 15% |

| Berserk | 15% |

Tips for New Heavyweight Fishing Players
Redeem SON and Riku first, because they need no level.
Save rerolls for the rare traits, since the common ones show up on their own.
Count your summons, because a rare skill is guaranteed at 30, 120 and 1,000.
Put your early cash into a better rod before you chase bosses.
Skip the 50 ticket pack, because it costs more per ticket than the 10 or 100 pack.
