@JeremyECrawford can an elf concentrate on a spell while meditating (long rest)?

No rule prevents an elf from concentrating while using the Trance trait. #DnD https://t.co/6pyvimyzWk

The concentration rule lists the things that end concentration. Trance doesn't qualify as any of those things. #DnD https://t.co/jmABwngqNG

@Dan_Dillon_1 @armando_dovalMostly just musing on the nature of Trance, touching on rest/sleep in general. Outside rules set. I understand. When wondering whether X ends Y and Y is only ended by Z, the key is determining whether X = Z.
