Valliars – The Mystic Pets
Mod “Valliars – The Mystic Pets” introduces new mobs to Minecraft PE, replacing all existing child mobs. These newly added creatures are extremely rare, and if you happen to encounter them in the MCPE world, I highly recommend taming them immediately. They are incredibly useful, making them the best pet mobs in Minecraft Pocket Edition.
Taming Valliars involves new mobs that take the place of current child mobs. The spawn rate is just 5%, meaning finding these creatures will be quite challenging.
You will know you have found a Valliars mob if you see a creature resembling a child running away from you.
To tame it, use an enchanted apple (with a 50% taming chance).
Once tamed, you can choose from three different sizes for the mob.

Equip Valliars with various armors and weapons. However, simply providing them with weapons is not enough. First, Valliars must learn specific weapon skills in Minecraft PE.
Damage
After equipping a mob with a weapon, you need to train it in combat skills. Below are the items you should give to the mob to teach it how to fight.
The damage dealt by the weapon will improve over time. Once the mob masters the diamond sword, it will have reached the highest level.
Speed
Agility is a crucial aspect of being a good warrior. Here’s a list of items you should use to train your mobs.
You will know the mob has reached its highest level when it starts wearing diamond boots.
Health
Another important attribute is health. To increase a mob’s health, give it one of the following items.
When the mob wears a diamond chestplate, it will signify that it has achieved maximum health.
