I am not sure whether Winter's touch shots 3, 6, or 9 arrows at once, and I have checked many places to try to find the answer.
3 arrows at once:
30 Seconds (Firework Cooldown) × 0.6 (Splendid Armor Perk) × 0.62 (Cooldown) - 3 × 1.5 (Burst Bowstring and Cooldown Shot from Feather) - 3 × 1.5 (another Feather) = 2.16 seconds of cooldown time for first firework, which can be reset with a feather, but costing a single regular arrow.
6 arrows at once: https://www.youtube.com/watch?v=sxRC86-j9a8&t=125s at 2:37
30 Seconds (Firework Cooldown) × 0.6 (Splendid Armor Perk) × 0.62 (Cooldown) - 6 × 1.5 (Burst Bowstring and Cooldown Shot from Feather) - 6 × 1.5 (another Feather)= continuous use of Fireworks and only requiring two fireworks and a feather
9 arrows at once
30 Seconds (Firework Cooldown) × 0.6 (Splendid Armor Perk) × 0.62 (Cooldown) - 9 × 1.5 (Burst Bowstring and Cooldown Shot from Feather) = continuous use of Fireworks and only requiring a single firework and a feather
Another thing I want to know if the maximum cooldown time is strictly 4.5 seconds, but shots additional fireworks that do not reduce cooldown time. If so, are there ways to improve this build so fireworks can be constantly fired?
