Light Cones are Path-locked weapons: same-Path characters get the full passive. Use this tool to compare listed cones by stats — then confirm effects and Superimposition text in-game. Ignore any older site copy that invented cone names.
Higher ATK / HP / DEF on a cone helps everyone, but the passive is usually the larger gap between options — especially on Harmony, Nihility, and Preservation supports. A lower-rarity cone with the right SI text can beat a mismatched 5★ that only contributes base stats.
When two same-Path cones look close on paper, check Energy Regen, Break Effect, Effect Hit Rate, and follow-up / DoT riders against the kit you actually play. Then farm relics to match — cone choice rarely fixes a wrong body or feet main.
