From the Monarch release notes

Once the card changes zone, for example, enters the graveyard after the combat chain closes, it will have phantasm again.

Keyword notes

Spellvoid - Spellvoid is a new keyword primarily on equipment or items. Spellvoid is a one time use effect that prevents arcane damage.

Shock Charmers

Lightning Equipment – Arms

Instant

–

: The next time an attack action card you control hits a hero this turn, it deals 1 damage to them.

Spellvoid 2 (If your hero would be dealt arcane damage, you may destroy Shock Charmers instead. If you do, prevent 2 arcane damage that source would deal.)

Defense: 0

Spellvoid does not go on the chain as it is not a trigger. It is a replacement effect. There is no time to respond after the decision to destroy the card and prevent that damage.
Spellvoid is optional. You choose whether to use spellvoid or not at the time the arcane damage resolves.
If a card has Spellvoid 2 but only prevents 1 arcane damage, there will not be a leftover prevention shield. Note: It can only defend arcane damage from a single source, Spellvoid 2 cannot prevent one arcane damage each from two different sources.
Spellvoid does not go on the chain as it is not a trigger. It is a replacement effect. There is no opportunity to respond after the decision to destroy the card and prevent that damage.
If a card dealing arcane damage is fully prevented by spellvoid (Or in conjunction with other preventions) it would not be considered to have dealt arcane damage and would not trigger effects that rely on arcane damage being dealt.
