I did use 1 etheric light on my vog helmet bc I love it...and used a shard on my heart of praxic fire to reach 33..so I can do the 34 PoE and save a bunch of etheric lights..might make 1 character 34 just so I can get the weapon core..I'm not grinding my ass off trying to get there..but if rng blesses me why not? Haha
