Tips for inivisble:

Click inside the radius of invisibility, this will stop fast raiders from decloak.
Merge as many units, if you are going very very far, chances are you won't get reinforcements.
Don't attack a static defense you couldn't beat normally. Serious, inivisblity makes your inivisble. That's it.
Make sure nothing decloaks.
Don't lose sneaky (I did) or your retreat force is screwed.
You can make Djinn to teleport your units back if your going to be detected (seeing radar dots), or when you are under fire. Teleport Eraser first, then Raider, then Assault, and finally Riot. Riot is meant to hold out so you can evacuate everyone.


Thabks Corvus for Sneaky pete morph, but I prefer Athena because I can get other units from it, some which could be most helpful (Halberd+Recluse) or I can Ressurect/Reclaim. Your one of the most helpful people I know here Corvus!
