Lightsaber Crystals....
Some of the less cosmetic, genuinely stat changing ones should be on the restricted items list or at least require lengthy quality dev threads, in my honest opinion. CEC, meditation crystals, some of the simpler natural ones. They should all be a
thing. Abilities like underwater use or being the only one capable of activating it are really rudimentary abilities. I feel it a huge injustice to absolutely deny the existence of all crystals' minor abilities. It, if you'll excuse my outspokenness,
kills half of arguably the most iconic part of Star Wars; the lightsaber. It's not like anyone is going to pull a Kaiburr shard out of their arses, and even then, it doesn't have to be listed as is with most of the game-breaking crystals.
That is all, everything else is 100%. :3
