Idea that discourage the use of going to spectator while toming

[Slayer]

Eh, that doesn't exactly answer the main question.  I should have specified that I meant the prep time directly after respawn waves.  If tomes will only allow something that is already allowed during this time (Replace Items) then what happens if one is used during this time?  Will there just be no effect, or should something be added such as increasing the time or giving people the ability to respawn twice during this time?

Depending on how many times are used, add an extra re spawn counter for each used. IE:

Re spawn wave = 1 respawn counter
Use a tome in this time period = 1 re spawn counter
Use another tome = another re spawn counter

Once RC (res counter) hits 0, grey out the replace items option.
