Guide to Arrows with Effects
In the new version Minecraft Pocket Edition 0.15.0, new types of arrows were added - arrows with effects that apply various effects when hitting an enemy. This is very useful, and since many don't know how to make such arrows, we decided to write this guide.
So, first you need to get a cauldron and place it on the ground. Then you need to get a potion and tap it on the cauldron. The cauldron will partially fill with the potion, but we decided to fill it completely. For this guide, we used an invisibility potion, but it doesn't matter which potion you use, because you can make an arrow with any effect.

Now you need to take a regular arrow, the crafting recipe of which I think many know, but if you forgot, we have attached a screenshot below.
Take the arrow in your hand and approach the cauldron filled with the effect potion. All that's left is to tap the arrow on the cauldron.
As you can see in the screenshot below, you will get an arrow with the invisibility effect and its icon will change.

Now, when you shoot a mob with an arrow of invisibility, it will, not surprisingly, become invisible.

If the mob has a weapon, it will still be visible =)
