So, no one bothered to review the level 0 version, probably because it was clearly a trade-off: investigator A spends an action to give an additional action to investigator B so collectively there is no action gain, simply a transfer from the one that probably has the most important role (getting the clues). But you had to include the card in your deck instead of one actually helping you to fullfill your role (or helping the other investigator to fulfill his/hers).

This version gives an additional bonus: all the - 4 - actions get a +1, which is a good thing (comparable to half an Encyclopedia but for all skills) ... but shines if investigator B is a rogue using a few of the events that add to skill values (Cheap Shot, Slip Away and Breaking and Entering).

And in a "big hand" deck you also have the option of using Farsight to play guidance as a fast event to avoid the loss of an action.
