Save the Embertail by reworking how the "Burn Damage" debuff interacts with other sources of itself.

This is a somewhat complex issue with the game, but my core (no pun intended) reason for posting it is to make the Embertail a more viable/fun pet. However the issue effects basically every class, even if you don't have an Embertail--the Embertail just makes it worse.

The gist of the issue is that the "Burn" debuff is completely overwritten when affected by Burn from another source. Where this becomes a problem, is where there are so many really interesting and really powerful items, skills, minions, etc, that work around the Burn damage stat.

Have a Fireball Staff + the Burn Damage skill from leveling up Blast? If another player who just happens to have anything that applies Burn (Tome of Ashes, Embertail, or literally anything from this list: https://core-keeper.fandom.com/wiki/Burn_damage) it COMPLETELY REMOVES your Burn damage.

This also means that YOUR OWN EMBERTAIL will prevent YOUR OWN Burn Damage from functioning

This makes Embertail an actual debuff to a co-op playthrough
