[RAI] Hidden and hostile non-Action abilities

[Piezoelectric]

The Problem:
Hidden currently states that the character Hiding loses Hidden if they make a "hostile action". However, some passive abilities (Scorpion v70.1, Balor's Scouring Swarm trait) do not require actions of any kind, but still inflict hostile effects. RAW, these would not break Hidden.

The Solution:
Either keep the wording as-is and allow this behavior, or amend the wording to "hostile actions or hostile abilities".

The Location:
Pages 69, 77.

Raleigh's Full Metal Jacket trait and Ranger Swallowtail's Grounded Trait have similar wording

Relevantly, there is a discrepancy between what breaks hidden on page 69 and what breaks it on page 77.

Page 69 says "a hostile action (such as forcing a target to make a save)" while page 77 says "forcing saves."
Lock On would be a hostile action (probably), but does not force a save; an NPC triggering a mine is not an action, but it does force a save.

Suggested action: remove most of the text describing Hidden on Page 77, and instead refer to the rules on Page 69.

There's also no established list of what constitutes a hostile action. Some candidates: Scan, Lock On, placing mines, placing Javelin Rockets, Mark for Death, Jackhammer rounds (if a character is damaged by it), reloading the Cannibal shotgun.

Suggested action: replace the text "a hostile action (such as forcing a target to make a save)" with the text "any action that immediately forces a save, applies a condition, or deals damage to a hostile character"
