Mob Behaviour
Two optional tweaks take away the vanilla weaknesses that get in the way of farms and arenas: water hurting endermen and blazes, and undead mobs burning in daylight. Both are off by default and live at the top level of config.yml.
They apply to every mob of the listed types on the server, not only EcoMobs or mobs from spawners. Run /ecomobs reload to apply changes.
Water sensitivity
water-sensitivity:
enabled: false
mobs:
- enderman
- blaze
With enabled: true, the listed mobs stop taking damage from water — standing in it, rain, and bubble columns — and endermen stop teleporting away from it. An enderman farm can hold its endermen in water, and a blaze spawner can sit next to one.
Any mob that vanilla hurts with water can go in the list, such as snow_golem.
Sunlight burning
sunlight-burning:
enabled: false
mobs:
- zombie
- zombie_villager
- skeleton
- stray
- bogged
- drowned
- phantom
With enabled: true, the listed mobs no longer catch fire in daylight. They still burn in lava and fire, and from fire aspect and flaming arrows.
