This pack adds content to my previous pack, as well as fixing a few major. It gives zombies powerful abilities based on their name. To activate these abilities, simply type "/function tougher_zombies:start" into chat.This is still in testing, more zombies will come, but the current zombies are all still impressive. They are:

Boomer:
- Explodes immediately if approached. Far more dangerous than creepers
- Wears TNT on its head
Igniter:
- Spreads a trail of fire as it runs
- Holds a flint and steel
Runner:
- Gets an occasional speed boost from it's rocket
- Holds a rocket in its hand
Healer:
- Heals nearby zombies
- Holds a brewing stand and a golden apple in its hands
Builder:
- Builds shoddy structures around hurt zombies and returns them to full health
- Holds a pickaxe and bricks
Summoner
- Summons "Soul Mites" when near a player.
- Carries a soul lantern
Trapper
- Traps the player in cobwebs
- Carries a cobweb and a slime ball
Harvester
- Reverts growth stages of nearby crops
- Feeds off of nearby animals in order to heal itself
- Carries a stone hoe and an empty bowl.

In future updates, I plan to add:
- New Strengthener zombie that works like an Enchanter from Minecraft Dungeons
- More abilities for the builder (i.e. breaking down walls, pillarring up)
- Zombies with abilities spawning naturally
- Fix whatever bugs are found and make it more survival friendly
- More zombie types (though I'm out of ideas please help)

Please let me know in the comments if you have any ideas for other types of zombies. Also, since this uses "/attribute" and the "Soul" particle it only works in 1.16.

Finally, here are the bugs I fixed:
- Zombies power ups all activate at the same time.
- Getting to far away from (0,0) disables certain zombie abilities
