Dark Necrofear questions

[Raigekick]

1) Does Dark Necrofear's effect works on either player's End Phase?

2) What is a die roll?

Netrep Card Registry states:
[tt]6. If "Dark Necrofear" attempts to equip itself to an Archfiend monster and the Archfiend die roll is successful, "Dark Necrofear" will be destroyed and sent to the Graveyard.[/tt]

3) After Necrofear is destroyed while being treated as a equip spell card, is his effect still active?

Curse of Aging (based on what I have read on it) will not apply to those cards Summoned afterwards (partly because a ruling states that it does not affect face-down monsters).
