when to expect next ambrosia event? happy hours etc.

The happy hour-actions are not announced far in advance. However, you can expect them to return often (less than a month waiting time most of the time I think). Just be patient.

How often is the ambrosia cashback and what is the highest percentage we can get?
Thanks in advance

From my exp, aprox 4 times a year and the only percentage they give is 10%.

There are multiple different things:

• cashback when you can get back X% of spent ambrosia in a particular time (usually 10%-20%)
• discounted items when the price for various items is decreased for X% (usually 20%-50%)
• the happy hour when the price of ambrosia is deducted for X%, or in other words you get for X% more ambrosia for the same price (can be 10%-100%)
