Elite Boosts

I am confused as to spending alliance treasury gold on elite boosts.

Do you lose the gold in the alliance? As you will need to donate more?

If you do lose alliance gold, can you level down?

 

Elite boost uses gold accumulated in the alliance bank. It’s the same gold used for upgrading your alliance. You cannot go under 0 gold and you can’t loose levels.

To clarify things, the gold you use to buy boost or upgrade is spent. So you will have to get more gold to keep the boosts active, activate new boost or to upgrade your alliance.
