Idea for Frozen Spear

I have a suggestion! What if you added a special "frozen" variant to the spears coming in the Mounts Of Mayhem update. What I mean, is that if you hold any tier of spear in an Ice Spikes biome for a minute and a half, it becomes a frozen version of that tier. For example, a Gold Spear becomes a Frozen Gold Spear. It could look like a regular spear, but with a rectangle of ice around the sharp part, preferably hanging towards the ground. It would give it the following effects:

1.It gains 100 durability

2.It deals half a heart of damage to the user whenever it is used

3.It gets heavier, as in it goes through the three stages in the charge attack faster

Of course you can change these features if you want. :)
