Archived posts from Everlore showing discussions about rangers getting Chloroplast and never getting Regeneration to preceed it (dated as early as May 2000, I can't seem to get to page 2 of this forum discussion to see earlier entries, maybe someone else can). This at least proves that the spell Chloroplast came before the June 6th patch
Also entries for Firestrike as early as 6/28/2020.
