In the loyalty pet slot totem's description it says it needs a GA active to use it. Does this mean I need the GA to activate the totem or does it mean I need the GA to use the extra slot?

You can activate the loyalty pet slot at any time, but you need to have an active GA in order to use it.

Thanks!

Hmm... I think I'll probbaly be pick a different totem from the loyalty box then.
