Finally, your snowman (snow golem) army is not completely useless anymore.
This small mod makes snowballs thrown by snowmen cause a small amount of damage.
Thereby they can finally protect themselves from these evil monsters.
You want your army to grow? Then you can enable a config option which makes snowballs convert mobs to snowmen when they die.
With default settings snowballs thrown by snowmen deal a small amount of damage to any hostile creature (0.25 hearts). With that, it takes about 40 snowballs to fight a zombie, but if you have enough snowmen this should be quite quick.
In addition the snowballs freeze (slow down) the hit mob for two seconds, thereby the snowmen have an even better able to defend themselves.
Snowballs thrown by players do not deal damage, by default.
Most of this is configurable.
If you want to use this on a server, it is sufficient to install it on the server itself. Clients do not need this. However, it does not hurt.
Can either be done in the ingame mod list GUI (MC1.11 or higher) or by editing the config/enhanced_snowman.cfg
