- Once you have the 3 maze partners, you cannot invoke any permanent allies any more. It is unknown at this stage whether Image of Demi-Gods and Semi-Devils is an exception like in Cloud Island or not but it is presumed to be.
- For the task about reaching level 70 without upgrading the engineering manual, you do not have to fear upgrade rewards from the buildings, you can still achieve the task after having received some of those.
