I wrote awhile ago an article about oasis but I didn’t wrote about how to grab an oasis from another player because I never got the chance to try it.

I seem that it takes awhile before you can grab an oasis from another player not like they say in the forum thread.

When you attack an occupied oasis each time the loyalty of the oasis is reduced by somewhere between 0% and 35 % not 35% like they say in the forum thread.

It seems to depend on how many troops you’re using and if you have a hero or not.

My last wave had two heroes in it and they took the oasis, but I don’t think it’s really matter the just attack constantly and the oasis will be yours, after a while.

Note that the oasis does regain loyalty each hours so be swift with your attack.
