Witch Tiers (USE FOR BATS)

In My Opinion Witches need to have a tier like this

-normal witch

- "medium Witch"

-boss witch

the normal witch should be like the one we know already 

the medium witch should have 150% health of the normal one and a bat should carry slowness and weakness potions (no instant damage)

 The boss witch should only spawn in swamp huts and have lots of hp and 3 bats that carry potions (instant damage included) 

normal and "medium" should spawn normaly . The Boss one should spawn in Witch huts only.

And it should drop an item that makes potions more usefull like the potion Handbag for example 

leftclick to change the potion type and rightclick to throw. easy 

Since Villagers have Tiers I think witches should to. If Lightning hits a Villager it converts in to a Witch. So it is only logic that it transfers its "Tier"
