Rune Trial Stones

Rune Trial Stones are floating structures which can be interacted with to attempt a Trial. Each trial has a different goal, time limit, and weapon. Completing a trial successfully will yield Runes, which allow further abilities to be used in combat.

They first appear in DOOM. They are large boulders that glow green, with a large glowing green rune on them. They also give off a loud, continual deep whispering similar to that of a Gore Nest, which likewise is often the first signal to the player that there is one nearby; they also let out a high-pitched buzzing of sorts which becomes noticeable upon approaching the Stone. After passing the trial, they crumble into a small pile of rubble with a much weaker green glow.
