Terraria
Different versions have allowed items placed in frames or related containers to be duplicated through save or interaction timing. It is a famous Terraria exploit category.
Players use hammered blocks and collision quirks to propel characters through walls, upward shafts, and ultra-fast travel systems. Hoiks are one of Terraria's iconic physics exploits.
Slopes and half-blocks can force unusual enemy or player positioning, helping farm setups, traps, and compact transit routes work more efficiently than expected.
Wire-triggered statues can generate certain enemies or resources repeatedly, accelerating item farming and progression when combined with optimized arenas.
Carefully stacked regen sources such as honey, hearts, stars, and campfires can trivialize otherwise difficult boss attrition, turning arena setup into a sustain exploit.
