Resilience - Resist Toxins

Characters may be subject to toxins of all sorts in various kinds of environments. They might get bitten by a venomous desert snake in the Auroch Pridelands, be the victim of a poisoning at a royal court in Cascadia, or inhale the spores of a strange fungal creature in the wild forests of Kaldaria.
The Genesys Core Rulebook does not offer clear guidelines on how toxins work. Fortunately, there are many examples in all released Genesys official books, and they all share common features. A toxin has a negative effect, which might Cause the character to suffer wounds, strain or any other adverse effect, such as paralysis, unconsciousness, etc. The numerical value of the effect is either fixed, depending on the number of h generated, or a mix of the two. Whatever the effects and their duration, the character only makes the check once, at the moment they are poisoned. Of all poison effects from the book aside from the Poisonous additional effect of the Magic Attack action, the character has to make an additional check to avoid suffering the Poison's effects again on the next round if a d was generated. Therefore, constantly rolling d means the character will remain poisoned, suffering the toxin’s effects constantly. One poison, from the Serpent Dagger, extends its duration even on hhh. Keep in mind that this is the rules as per the Genesys core rule book, instead of the long term more "burn" like rules used for poison in this setting.
Suggestions for other symbols were added since the book did not provide information regarding those.
At the time of writing this document, all the poison effects from the official books allow a character to make a Hard (ddd) check to resist toxins; the sole exception to that is the Serpent Dagger (see page 110 of Realms of Terrinoth), which forces a character to make a Daunting (dddd) check. Note that it is a magic item that does not have a monetary value. Therefore, most poisons would require a Hard (ddd) Resilience check, unless the poison or the circumstances are exceptional in some way.
EXAMPLE OF A RESIST TOXIN CHECK
Heidi is scouting ahead of her party as they are travelling through the underworld — the vast underground tunnel network that spans the whole planet, filled with dangerous creatures and flora. Heidi enters a room with fluorescent fungi. As she reaches the center of the room, the fungus emits a piercing sound and secrets noxious spores that fill the whole room.
The poison has the character suffers from 4 strain, plus one 1 per h, unless she succeeds on a Hard (ddd) Resilience check.
The check generates faa. From the failure, Heidi suffers 4 strain. Since this room is the only way to go unless she wants to backtrack for hours, Heidi's player asks if they can spend an a to have only a single toxic fruiting body in the room and the other a to have their character spot it. The GM asks what is the player's intention, they reply that they want to cut it off, neutralizing it. The GM agrees but says that Heidi will be exposed for another round in the process, to which the player agrees.
The player rolls the dice and generates sshh. Heidi resists the effects of the fungus. One of the h is spent to have Heidi suffer 1 strain as she fights off the toxin. The GM spends the other h to have a predator be drawn in by the fungus' noise. It will stalk the characters for a while before ambushing them while they sleep.
