Gamebreaking items.

Manastone = unlimited mana after CH for clerics. If it was usable in kunark/velious, would be absurd.

Of course as everyone else mentioned a whole host of instant click items have huge impacts on raiding in ways that fungi tunics do not.

I personally don't mind the OP items like this. Items like this make an impression as you are leveling. The allure of stuff like this and how out of reach some Of them seemed added a level of mystic for me when I first played eq and offer something beyond incremental hp/mana/ac to strive for that feels far more worth striving for. It's funny bc I think a lack of testing led to some of the coolest things in game for me. Beyond just items like this, also stuff like raid content being a little too hard for its era. Thinking plane of sky pre kunark, AoW velious, etc. the lengths people went to beat this stuff is pretty crazy in hindsight. I was explaining to a friend that 90+ people worked together to kill one thing, how ch chains have to be set up, etc and it blew his mind that people organized things like that.
