I know this isn't standard content, but here's the condition I saw on the character sheet after using the wizard to build my character.

Created a druid of the Wildfire Circle; on the sheet, the Wildfire Spirit ability is shown with a "number of uses" count. This should be equal to the number of uses of the Wild Shape ability. For a level two Druid, it should be 2. For the character that I rolled up, it shows as 14.

So, it could be user error, but it seems more like a math bug somewhere...

This is covered in a pinned thread on the Unearthed Arcana subforum.

ISSUE: Wildfire Spirit - the creature stats are shown under the feature on the character sheet, rather than as a separate creature added through the extras panel. The "number of uses" is configured to allow tracking of hit points. The attack doesn't show the attack bonus.

Made a Wildfire PC today, still getting the bug.

Quote from Halfwing >>

According to the wording of Summon Wildfire Spirit:

As an action, you can expend one use of your Wild Shape feature to summon your wildfire spirit, rather than assuming a beast form.

The intent is to check off one the uses of Wild Shape when summoning the Wildfire Spirit.

 I'm a level 2 Druid, and there are (2) boxes under the Wild Shape area, but then under the Wildfire Spirit, it shows: Uses [-]15[+], which I thought is a bug, but then I tried adding up the Wildfire Spirit stats and I guess its health does add up to 15, then I tried leveling up to 8, and it shows 45, while the spirit's health should be 5+ five times your druid level, so maybe its that? It's just confusing 'cause it just says "Uses: 15/ Special"
