再請教一個Wizard的問題 - TRPG

Wizard Paragon Path: Spellstorm Mage

Storm Spell (11th level): Once per day, you can reach into the spellstorm
and extract a spell you have already used so that you can use it again.
Make a Wisdom check. The result indicates the kind of spell you can extract.
You can instead extract a spell using a lower result than the result you
rolled, if you so choose.

我想請問在戰鬥中使用這個能力是什麼Action?
Free, Minor, Move or Standard?
