Can anyone explain me how does these 3 actions work

Well as far as I understood ... I set up linkdrop command each 10 sec , then when I lose link in sunny area . If Im not affected by Novoide, I will disappear into void,and therefore I don't sunrip.
But what if I set up linkdrop command each 10 sec , then I lose link in sunny area,and Im affected by Novoide . Which means I won't disappear into void . Do I sunrip after all?
I mean Im like 80% of my mume session affected by novoid :p , if it has to do with sunrip, so linkdrop action won't help me much

The help file about sundeath stipulates :
oO W>help sundeath
SUNDEATH
Trolls can be instantly killed by the sun. Trolls sundie:
- With link, in sunlit areas.
- Without link, in sunlit areas, when affected by NOQUIT or NOVOID.
Trolls don't sundie:
- Without link, in sunlit areas, when not affected by NOQUIT or NOVOID.
These deaths are "permanent" and reduce the character to level one.
