Well the ascension update page says:
DESCENSION:
This is now active. To descend someone you must attack their god directly, by yourself, as a god. You must first beat their physical defences (advisable to remove them before trying a personal attack on them!), and only then will you be able to assault them directly.
The concept is that life force is your max attack - which is then multiplied by your attack stats.
Their life force is their max defence - again multiplied by their defence stats.
Damage is done to each god, and this value removed from your life force AND RESERVES if it is greater than you life force. This is true for attacker and defender.
A maximum of 1/3 of their total reserves maximum can be destroyed each hit.
An ascended battle takes 4 realtime hours - so you cannot attack if you or they have/are battling (ie its been less than 4 hours since last battle.)
When reservers + life force is zero - they are descended.
Descended accounts cannot take any action on ascended for 14 days. Then get a 4 day protection to remedy their failures

. (this is the 'release' values. They may change over time, based on your feedback).
While descended, the main account gets no bonuses from the ascended account.
The main page updates say
Ascended Account Effects on Main
*In preparation of changes to the ascended server coming early this week, the following changes will affect the main server:
*If you are on vacation in ascension, you ascended bonuses on main are halved. You still get ALL your bonuses, but at 50% strength.
*If you are descended in ascension, you do not get ANY bonuses in main.
*The above 2 statements only apply if you are playing an ascended race in main. And of course if you have an ascended account

So I am guessing that after fourteen days you get your ascended account back, which means your bonuses too.
