Clan Activity/Clan Points

[Daichi]

Say your clan has 200 clan points and is ranked 16 in your village.
Now say the number 1 clan has 500 points. How long were these points aquired?
Are they a week's total of points/raidkills or what. How long do they last for?
Also how does your clan get percentage based boosts for offense and defense.

I believe that clan activity points build up over a week until Thursday, when they decay by a certain percent.
I'm not sure what this percent is, but I'll check this Thursday and add it to the manual's clan page.

Clan leaders upgrade their clan's offense/defense bonuses via the "Upgrade Ability" link on the clan control panel.
Activity points and clan funds are awarded for each PvP kill; activity decays, funds don't.
