Saw this on Facebook and there wasn't much consensus as it's such a tricky one.

If you use Ichor Gauntlets to copy an event, can the new target be one that is immune to enemy events?

Reasoning: Ichor Gauntlets only copies the effects of the event, and is not itself an event.

Immune (RRG, p. 8)

If a unit is immune to a specified set of effects, it cannot be targeted or affected by effects that belong to that set.

Ichor Gauntlet

" Reaction : After you resolve a Torture event card, exhaust attached warlord to copy its effects. You may choose new targets."

So the real question here is what resolves when you trigger the Reaction on Ichor Gauntlet. If it is the event that resolves, the effect would belong to the set "events" and "immune to events" units would not be hit. If it's anything else, you're outside the set of effects "immune to events" units are immune to.

To answer what resolves, look at what triggers. You trigger an attachment (Ichor Gauntlet), which the copies the effect (but does not trigger ) the event you are reacting to. Since the event is not (re-)triggered when you use Ichor Gauntlet, it's hard to see an argument that it is the event - not the attachment - that is resolving. Since there is no event resolving, the effects being applied cannot be event effects - and are thus outside the scope of "immune to events."

In a nutshell, "immune to events" protects against the original event effect, but you would need "immune to attachments" in order to protect against the effect copied by Ichor Gauntlet.
