A mod that adds new behaviors and quirks to having the Ender Dragon Egg. This mod is intended for use on the umacycrimes' Crime SMP or other server environments but does work on client side.

A list of all the quirks that are currently implemented follows.

Buffs when the egg is in your inventory

+5% move speed bonus.
Silly ender particles spawn around you.
+2 armor points.

Buffs when it's held in either hand

Damage boost equivalent to strength 2.
+4 armor toughness.
+10% move speed (only in the main hand) for a total of about +12%.
Can perform pogo starting trick if the mace is in the main hand.

Nerfs

Portal sickness (Bad Omen 15min, Slowness 2min 30sec, Nausea 30 sec, Blindness 15 sec).
Perma visible on the locator bar (mostly).
Chance to spawn a vengeful enderman when killing a humanoid (It can happen very rarely without the Egg).
Ender particles spawn more than normal when held (Could be distracting).
Unable to put the Dragon Egg inside a bundle normally.
Increase Warden aggression while having the Egg.

A Karma System (Only active while holding the Egg)

PvP (should) impact karma more than PvE.
Combat-logging hurts karma.
Starting a fight slightly hurts karma.
Someone else starting a fight with you boosts your karma.
Fighting back will boost karma.
Killing certain mobs under certain conditions will either boost or hurt karma.
Killing a player significantly weaker than you dramatically hurts karma most times.
