talic, refsSpoilerJust to clarify: The official ruling is, anything that is 24 hours duration, like blood quickening and some of the warlock invocations, are in place before the match. However, just like memorized spells, if it's not claimed before the match starts, it's not in effect. 1 hour of meditation is correct.
Just laying out some info, keep the action rolling.
