[MC-70211] Mining fatigue amplifier 4 or higher allow instamine items to be broken

Previously, Mining Fatigue status effects of high levels would make the player unable to break any block. Now, it is possible to break instamine blocks.

How to reproduce:

1. Create a super flat survival world with cheats (redstone ready).
2. /give @p torch
3. /effect @p minecraft:mining_fatigue 100 4
4. place the torch on the ground.
5. attempt to mine the torch. It will break.

This is NOT a duplicate of MC-10755. That bug is a blanket bug that was dismissed a long time ago. This bug refers to a specific issue with mining fatigue.

Not a dupe. Don't get why these mistakes are always made.

Potion effects beyond level 4 are not supported.

Firstly, they should be. Mapmakers use them a ton. Secondly, Mining Fatigue of exactly level 4 (Display level 5) works exactly like mining fatigue of higher levels.

Yep. Pretty much.

Confirmed and updated description to keep the amplifier in the "valid" range

Ely G 2015-08-24T19:04:39Z

Update: According to the wiki, this is intended. See http://minecraft.gamepedia.com/Status_effect

the behaviour was changed in 14w25a such that mining fatigue is no longer a linear 20% decrease.

Ely G 2015-08-24T19:33:00Z

Interesting. I think the resolution is "works as Intended". why invalid?

EDIT: thanks.

Whoops, I was thinking of MC-10755. Fixed now.
