Since 1ce has started adding 'legendary' mobs into the server, there should be a topic where we can submit ideas on what we think mobs could be and/or what abilities they will have.
FORMAT:MOB: What the mob is e.g.. pig, zombie ect...
POKEMON: What the mob represents e.g.. Scyther, Rhyhorn ect...
ABILITY: What effects these mobs can have eg. lightning, knockback aura
As backpackcat suggested:
Squid can act as a
tentacool/tentacruel throwing splash potion potions (this is somewhat similar to the witches) These just have a chance of poisoning you if you attack.
Articuno:
Can induce a slowness effect to mimic slowness when freezing
Zapdos:Could possibly have players around it zapped with lightning. 1ce said /smite wouldn't work, but there may be a way around that.
Motlres:Could be a blaze.
Otherwise, the original idea of a chicken with a burning aura.
Zubat:Obviously the bat mob.
Non-Legendary VersionCould have a percentage of spawned bats add a short confusion potion effect when a player gets within a certain radius of the target bat.
Legendary VersionCould also have the possibility of
Leech Life. This would drain life (health) from the player, and heal the bat mob. The mob would probably have boosted health too, like the other legendary mobs.
These are just a few ideas. Submit your own to get some more legendaries
