A player, 14 October 2014
If I invest Isawa Orinoko, and she dies, and I bring her back into play (with Blood of the Preserver, for instance), my impression is that her gold cost, since I invested in her, is 15 permanently (unless she becomes face down and out of play). She also permanently has the Fear 5 and Conqueror. However... does she re-enter play with the three +1F/+1C tokens? And, if not, can I invest her again to give her a second Fear 5 and refresh the tokens?
Invest : Give Orinoko three +1F/+1C tokens, then permanently give her Conqueror and the ability, "Fire Battle: Fear 5." This Invest cost cannot be reduced.

She would not get the tokens back, as they would have gone away when she left play and her re-entering play does not trigger reapplying them.
