<p>This is a fairly simple idea: branding irons, which would be used to name mobs, in a similar fashion to nametags.
</p><p>Branding Irons would be crafted like so:
</p>
<table class="wikitable" border="1" style="text-align:center"><tr><th> Vanilla
</th><th> Crafting
</th><th> Table
</th></tr><tr><td>Empty
</td><td>Nametag
</td><td>Empty
</td></tr><tr><td>Empty
</td><td>Iron Ingot
</td><td>Empty
</td></tr><tr><td>Empty
</td><td>Stick
</td><td>Empty
</td></tr></table><p>
</p><p>The resulting tool would have durability of say, 100 uses (Or something like that), and would be used by right-clicking a mob. If the mob is nameable, a text box would appear, in which you can type the creatures name. The Branding Iron would be repairable with iron ingots at an anvil.
</p><p>Yeah, thats really it, thanks for reading.
