I have a level 2 Wizard. Player's handbook on page 158 says:
After an extended rest, you can prepare a number of daily and utility spells according to what you can cast per day for your level. You can’t prepare the same spell twice.
So, as far as I understand I have to prepare utility spell to use. And at level two I can have one utility spell prepared. Then, "Attack powers and utility powers" insert on p. 15 says:
You can use encounter powers many times during a day of adventuring, but you have to rest a few minutes between each use, so you can use them each once per encounter.
and similar on p. 54:
An encounter power can be used once per encounter. You need to take a short rest before you can use one again.
Which to my understanding allows me to use any encounter power during a day (am I wrong here? Character sheet having separate sections for encounter and utility powers kind of supports me here).
Now, level 2 wizard gets access to the following "Wizard Utility 2" spells: Jump and Shield. Both have "Encounter" keyword. Do I still must prepare only one of these on any given day (and hence I can only use one of them multiple times on any give day) or I can use both at any given day any number of times (while honoring the "Encounter" restriction)?
