Today, SnapeTheSnipe, Wolfinsteen, and ninjaflame555 tested ninja's defense system.
Turns out, anvils cause damage to players. Death traps using these can still be made, but I have yet to see a death while playing normally. PS: it was a test for ninjaflame555 (https://www.opticraft.net/proxy.php?request=http%3A%2F%2Fi.imgur.com%2FETZ35.png%3F1&hash=ca62e696257a8a736a18a2192b6d4259ef148629)
Then we're just gonna have to toggle falling anvil damage off, if it's able to be toggled.
We are waiting on bukkit to update so that we can actually turn anvil damage off. If anyone is caught killing people like this they will be permanently banned.
Oh, okay.
You can lock this if you feel there is no more need of it
