1. A one-sentence summary of bug: 
The Wilder Crossbow can one-shot players with fireworks.
2. Priority to fix? {High, Medium, Low}
Low/Medium
3. Which server? {Spawn, Redwood, Cypress, Maple, Willow, Expanse, DungeonRun, Rush, Creative}
Tested on Elm and Cypress, so likely all tree servers. It will not kill at spawn but will bring the player to half a heart.
4. Steps to Reproduce: Please list the step-by-step methods to reproduce the issue
Load a Wilder Crossbow with a firework rocket in a tree server (only needs to be level one) and launch it at a willing player (it is sometimes difficult to hit the player for them to take damage at all, but with practice it is not).
5. Expected Outcome: What did you expect to happen?
I expect the player to survive or not take damage at all.
6. Actual Outcome: What happened instead?

The player dies in one hit (if it affects it, even in full netherite)
