The Pe-Sale
The pre-sale was very successful. One million CL Packs was sold and here's the top 7 people who bought the packs. The top 6 will be designing the Legendary summoners. My twitch buddy 
December 8th
Everyone is very excited and can't wait for December 8 to open their CL packs.
Each pack purchased during this phase of the sale will still require one VOUCHER token, not including bonus packs, just as in the presale, and a total of 2M VOUCHER tokens will be awarded to players with SPS tokens staked in their account over 30 days starting on December 8th, 2021 and ending on January 6th, 2022. The amount of VOUCHER tokens each account receives will be based on the amount of SPS tokens they have staked as a percentage of the total SPS tokens staked in the system.
General Sale
The Chaos Legion general sale is scheduled to begin on Monday, January 17th, 2022 at 12:00 EST / 17:00 UTC. The remaining 12M Chaos Legion packs plus any unsold packs from the second phase of the sale will be available for sale at that time for $4.00 per pack and will no longer require VOUCHER tokens to purchase, however VOUCHER tokens will be required in order to receive bonus packs along with larger pack purchases in a single transaction.
Please note that even if not all 2M packs are purchased during the second phase of the sale, the first two airdrops will still occur before the general sale begins and therefore will only be available to players who purchased packs before then.
