This oversized Rockster Boss cannot be met in any natural environments, but requires artificial lighting and crafted blocks to spawn during the day.
|Health:||1500 health points|
|Time to tame:||Becomes your friend in 10 seconds|
|Attack(s):||Swipe: Rockzilla swipes at players with its claws
Spinning attack: after ca. 4 seconds of blocking while covering itself with its claws, Rockzilla jumps and spins, sending player characters flying
|Location:||Player-made altars built with crafted blocks, only during the day|
Rockzilla has to be summoned by building an "altar" from:
- at least 40 crafted "temple-related" building blocks (not "Hidden Temple" blocks though) like Obsidian Brick Walls
- plus at least 20 natural beach-related blocks like Corals, Driftwood, Seashells or blocks of Shorewood, Shorewood Husk or Shorewood Leaves
- plus a large enough amount of lighting, like Moss Torches, Coal Torches, Bungalow Torches, Wood Burning Lamps, Arctek Torches, Arctek Lanterns, Fire Pits, Haunted Lamps, Haunted Pumpkins, (yellow, green, blue, red), christmas Holiday lights or Hidden Temple Torches. This makes Rockzilla the only Creature that needs artificial lights to spawn.
When building a flat platform from these "ingredients" then it won't take long for Rockzilla to appear when you visit the area again during daytime. It does not spawn at night.
Sometimes a Rockzilla might show up while still building this altar, sometimes it might take a few real life hours or ingame-days for the first Rockzilla to spawn.
Take care when you encounter this giant on a non-peaceful world, because Rockzilla is aggressive and his claws have a significant range!
If you have built your base (even just the floor) from temple-related blocks, then you shouldn't decorate it with too many corals or shorewood, because that might make Rockzilla appear in your home.
As long as the blocks and/or lamps that "attract" Rockzilla are not removed, another Rockzilla will spawn again at the same place approximately every ingame-day, sometimes even as soon as another player comes in range.
Please note that Creatures seemingly have resistances and weaknesses against certain types of Swords.
According to Playful, Rockzillas have 1500 health points, and based on tests they require 30 hits with a Lumite Sword to be killed.
You cannot hurt Rockzilla while it covers itself with its claws. Every hit that you deal to Rockzilla while it is blocking will only reduce the durability of your weapon, not inflict any damage to Rockzilla.
When killed or dismissed, Rockzilla might drop
- 1-5 Extractor
- 1-5 Coal Torches
- 2-5 Rockster Rock
- 1-5 Corals
- 1-5 (blocks of) Mud
- 1-5 (blocks of) Magnetite
- very rarely rare recipes, like for Sand Castle Walls
You can tame Rockzillas and feed them to harvest the same things from them that they would usually drop, sometimes in a higher amount. Rockzillas as Pets can either like Wholesome Pie, Melon Pie or Chizzard Pot Pie as their favorite food.
Here's an official statement about how to build an altar for Rockzilla from the developers:
"He does require a certain number of beach blocks -- sand is one of them but you could use anything found in beach areas (including coral, seashells, shorewood, etc.). ..." - PlayfulDavid, Feb 13th 2016
Since this statement was made things might have changed though, because blocks of Sand as for the beach-related altar building material won't make Rockzilla spawn, however Seashells that will spawn on blocks of Sand over time can seemingly help making Rockzilla appear, as long as the amount of Seashells is high enough.
However - much like with Saplings - sometimes an area might just not be to Rockzilla's liking, so it can refuse to spawn at certain spots even if you have placed enough (20) Corals, Shorewood, Shorewood Leaves or the like and enough (40) temple-related blocks together with torches...
Please note that Rockzilla will only spawn during the day and not during night-times. Building a Rockzilla altar close to your touchstone might prevent Rockzilla from spawning in some cases. Also if you stay close to a Rockzilla altar during the night, then no Rockzilla might spawn in the morning.
If too many other Creatures already spawn nearby (like on other Rockzilla altars, on artificial arenas that are too close or even in caves underground), then no Rockzilla might show up either in rarer cases.
Flat altars still work well, but pyramids or other structures might not make Rockzilla spawn anymore.
Also please note that it might simply take a while after building the altar (much like with any other artificial arena) until the first spawn is going to happen. It might take a few real life hours or two ingame-days in some cases for unknown reasons.
Currently (September 2016) Water is not a requirement to summon Rockzilla and won't raise the spawning rate.
Campfires and LEDs or the like are insufficient lighting to make a Rockzilla altar work. Obsidian Floor and pinkish-brown Hidden Temple blocks (like Hidden Temple Wall) will not make Rockzilla appear either.
Here are some examples for temple-related blocks that work well to make Rockzilla spawn (tested):
Issues with the hitbox and pet-harvests of Rockzilla have been fixed with R29. However it's still rather hard to hit Rockzilla despite its size. After taming a Rockzilla, its pet-window only shows a part of its large chest and you will have to aim at the floor below to activate him in order to feed the big guy.
