I ragequit runescape forever ago (before they upgraded the combat system) cause I walked into some area and suddenly with no warning whatsoever this stuffhead npc native runs up and stabs me with a poisoned spear and I get killed by overpowered poison damage before I can even warp back, losing everything in my inventory. And even if I did warp back, there is NOTHING, ANYWHERE that had EVER even MENTIONED poison before that point in the game, so there was no defense or cure that anything had ever told me about, nor was I ever told it even EXISTED.
I was very, very mad.
