Blood Raider Cerebral Accelerators to expire on Dec 1st (http://community.eveonline.com/news/news-channels/eve-online-news/blood-raider-cerebral-accelerators-to-expire-on-dec-1st/)

We would like to friendly remind every pilot that the Blood Raider Cerebral Accelerators and the Advanced Blood Raider Cerebral Accelerators will expire at 23:59:59 UTC on November 30th, 2016. This means, with December 1st you won't be able to consume those event boosters (https://support.eveonline.com/hc/en-us/articles/203217232-Cerebral-Accelerator) any longer. Anyone who consumes the boosters before that date will still benefit from the effect of the booster for its duration.
During the Crimson Harvest YC 118 (http://updates.eveonline.com/date/2016-10-18/) earlier this year, venturous pilots had the chance to retrieve those Cerebral Accelerators after successfully fighting the Blood Raider menace (https://www.youtube.com/watch?v=4qXrOLO7NwU). Those boosters, once consumed, increased all character attributes by +10 / +12 for a limited amount of time.
