cutthroat caverns – How does Alchemist’s Fireplace work together with Spite?

We have been having an encounter with Spite from Cutthroat Caverns just lately and got here onto an fascinating scenario, heres the situation:

Spite has 20 hp.
Initiative 1 had their assault cancelled.
Initiative 2 had an assault for 20, and in addition tipped their Alchemist fireplace.
Initiative 3 had an assault for 25.

Alchemist fireplace particularly mentions “flip”, which for me means you possibly can’t do it till your initiative is up, but in addition it would not specify if the tip occurs earlier than or after your assault hits.

In my thoughts you possibly can interpret this case in two methods:

1. Initiative 2 kills the boss when tipping Alchemist fireplace, for the reason that injury occurs instantly and isnt topic to Spite’s injury cancellation. Initiative 2 wins.

2. Initiative 2’s injury now totals 50, and initiative 1’s injury is 25. Initiative 2’s injury is canceled by Spite. Initiative 1 wins.

So I assume my questions are:

1. When does Alchemist fireplace injury hit?
2. Does it solely hit on the participant’s flip who tipped?
3. Does it stack together with your Set Assault?
4. Is it topic to Spite’s injury queueing/cancellation, or does that solely apply to common assaults?

Another unmentioned guidelines re: Alchemist Fireplace could be useful, as theres little or no element about it within the guidelines!
