I checked the FAQ but there was no mention of this, so I'll ask here:
If I use the Pocket Watch to repeat the Investigation Phase, perhaps because I'm engaged with an enemy and I don't want to get hit, do I actually have three actions to use? I just happened to be looking at the reference card from the core set, and noticed that "Reset Actions" actually occurs in the Upkeep phase. Cross-referencing with the Rules Reference, page 23 definitely lists Reset Actions under section 4.2, which indicates to me that while I can certainly pop the Watch to repeat the Investigation phase, doing so will not give me the three actions I normally have, meaning it's a huge waste.
Long story short, I don't think repeating the Investigation Phase works like you might expect. Any thoughts?
