So I was messing around with the 10th Anniversary Firework clicks. And I came across a spelling error, that has somehow survived the past 13 years! The 10th Anniversary events gave you a 'Celebratory Fireworks Caster' and a 'Fireworks Focus of Veeshan.' The 'Fireworks Focus of Veeshan' determines what firework effect you will see when you click the 'Celebratory Fireworks Caster.' There are 16 variants of the 'Fireworks Focus' (click to change it in a sequence of 16 variants). Anyway, the click item is correctly spelled as 'Celebratory.' However, on the Lore tab of the 16 variant 'Focus' items, it says, "Focuses the Celebretory Fireworks Caster' (thus the spelling error on all 16 variants of this item).
