Skirmish action lasts only for the skirmish they are performed. If you discard
Gimli's Helm to prevent all wounds o him, the wounds would be prevented only for his skirmish. So if a companion dies in the next skirmish you can't soack up threat wounds to gimli cause the ability oh helm is not active anymore (ended in the exact moment Gimli skirmish ended). Same thing with
Faramir, WP or
Promise Keeping.
I think there is a diference in Skrimish Phase relating to "a character skirmish or is skirmishing". If a companion dies it still skirmishing? i guess not cause all actiuons triggered by winning or lose already took place and (by the rulebook definition) the skirmish is already over so he/she is not "skirmishing" anymore. It's like you try to use any skirmish special ability between skirmish phases. Like using
Aragorn, DoFP text to heal a dwarf before threats wounds are placed. Keep in mind that
Gimli's Helm and
Faramir, WP text are not response actions and they last only for one skirmish, Also according to the rulebook the skirmish ends as soon as actions for wining/losing takes place (like placing wounds).
So i think this is just another gap that the rules let us to interpret, but i still belive that is the best way to look over it.
And yeah, always love cards like
High Vantage, i even taught in splashing cost 1 southron in a

deck just to make it soak all archery... But i think the main problem today is direct wounding so not sure if it would help...
