This this plugin has been merged into EnchantMore! If you want the same behavior as the original Sublimation plugin below, disable all other effects except for Pickaxe + Silk Touch, then set minLevel:1, and sublimateIce:true. Since EnchantMore encompasses the the functionality of Sublimation, this plugin will no longer be maintained.
Sublimation - silk touch ice, no longer overpowered
Remember in the Minecraft 1.9 beta prereleases, when the Silk Touch enchantment was first introduced, you could legitimately obtain ice? Minecraft 1.0 removed this ability as it was too overpowered: you could break ice and flood The Nether!
Sublimation gives you the best of both worlds: silk touch works on ice, but if you attempt to place ice in The Nether, it will vaporize immediately with a puff of smoke, just like emptying a bucket of water. Much more realistic, right?
sublimation.bypass (false) - Allows you to place ice in the nether
sublimation.collect (true) - Allows you to acquire ice by mining with silk touch
If true, turns placed ice into air, removing from the player's inventory
If false, cancels event, giving the player their ice back
Generate smoke particles, representing the sublimated ice
Enables the acquisition of ice as an item in the player's inventory, by mining it with a tool containing the Silk Touch enchantment. The player must also have the sublimation.collect permission.
If your server allows ice to be obtained by other means (creative mode, shops, trading, etc.), and you do not want to enable collection by silk touch, you can disable this option to use Sublimation just for preventing Nether ice placement as a security measure. When disabled, block break events are not registered.
