Seven-gem spectrum alignment and chromatic swinging
Added in 1.4.5, the Rainbow Phaseblade is forged at an Iron Anvil or Lead Anvil by combining 15 Meteorite Bar ingots with 3 of each standard gem: Amethyst, Topaz, Sapphire, Emerald, Ruby, Diamond, and Amber. Delivering 26 base melee damage at a Very fast use time of 18 ticks, this prismatic weapon cycles fluidly through the entire visible color spectrum with every slash, illuminating subterranean caverns with colorful hues.
Prismatic collection challenge and Phasesaber ascension
Crafting the Rainbow Phaseblade requires gathering every gem type in the subterranean world rather than harvesting a single deposit. It provides vibrant multicolored lighting while repelling pre-Hardmode cavern foes like Armored Skeletons and Cave Bats. Its broad swing arc and multi-color glow provide excellent illumination while charting unexplored cavern systems before Hardmode. Upon defeating the Wall of Flesh, fusing the blade with 25 Crystal Shard items yields the Rainbow Phasesaber. The Legendary prefix is the optimal reforge, enhancing weapon size, swing velocity, base damage, and critical strike chance.
Trivia
- Introduced in 1.4.5, the Rainbow Phaseblade unifies all seven underground gem varieties into a single cycling blade.
