Arctic Orangery, or AO for short, is an Arctic Future GB that gives you a chance at a critical hit against enemies the same age as your attacking units, and FPs on collection daily. The beauty of AO is that its critical hit chance doesn’t have a certain number of attempts, so it will just keep on going. In addition, that critical hit could be used by your defense army when someone attacks your city, should they be using units that match the age(s) of what you have set up for defense. The higher the level of AO, the more likely it is for that critical hit to fire. The FPs are a nice bonus as well, averaging about 1 FP per level (similar to Cape).
This chart shows locks at 1.9. Only 1/2 will ever be safe for a clean lock, from levels 38-62.
