Crater has a few Queues or "Prompts" that may require you to submit either Art or Written pieces. There are also Queues that DON'T require them, however PDs system can't function correctly if you don't submitting anything. I'll explain which Queues do and don't and the way to get around.
Queues that REQUIRE Art or Written Pieces will ALL need the following info:
1. Group Tagging

Please make sure that ALL submission that are for Crater have the Tag #CraterStarOfMysteries
2. Character tagging

These tags are VERY important and are the way that Crater Staff can keep track of Level gaining etc. This can be found on your CHARACTER page.
Please make sure to tag ALL Characters in your submissions or they might not get their rewards!
3. Level Gain / Crater Coin Gain / Trainer Points Gain and other additional information needed.
Please ALWAYS include this information in all your submissions in THIS FORMAT ONLY: Total CC Gained:
Level Gain for EACH mon: EXAMPLE = +1 (Inked Full Body) +3 (Cell Shaded Full Body) +2 (Trainer Bonus) +2 (Simple BG) = Total 8Lvs Trainer Points Gained: (Learn About Trainer Points)
4. Gift Levels (if applicable) (Learn About Gift Levels) In the SAME format as above.
