Sleeps underground until the bait for its own biome is dropped within three hundred tiles, then races to it, swallows it and blows a three tile crater open to start the fight.

Dives underground once a player is within thirty tiles, tunnels to one of five fixed spots tearing a two tile wide trench through the ground, then bursts out and smashes everything within two tiles.

Stays underground and cycles between fixed patrol points while nobody is fighting it, wearing a shield worth thirty percent of its health that fills itself back up.

Winds up for three seconds then fires a beam that starts two tiles in front of its mouth and crawls toward you, laying a new burning segment every fifth of a second and speeding up ten percent with each one, thirty segments from a single head and five fewer for every extra head.

It puts these on the ground:

Hydra Boss Beam Mortar Projectile

Bites at anything standing right in front of its head once the fight has started.

Right after the stalactites it slams the ground beneath itself and sends out a wave that lasts seven seconds and tears up every tile it crosses.

It puts these on the ground:

Hydra Boss Shockwave Mortar Projectile

When it is fighting alone it lobs one pod that opens into a nilipede, and the pod will not land on water or pits.

It puts these on the ground:

Hydra Boss Spawn Nilipede Mortar Projectile

It carries a shield worth thirty percent of its health, and the soft spot in front of its mouth only opens once that shield is gone.

If every player gets a hundred tiles away it goes back to sleep and the fight resets.

Druidra always fights alone and never grows a second head.
