The elusive ruby seadragon is probably the rarest fish in Dave the Diver. Catching one requires quite a bit of luck and determination. To help you out, here are some tips to help you catch a ruby seadragon and finally complete your Marinca collection.
Ruby seadragon spawn locations
Ruby seadragons have a small chance to appear when you mine rubies in the Hydrothermal Vents region. The layout of the region is shaped like a large basin with caves on either side. The resources that appear change every time you dive, and there are two possible locations where ruby nodes can spawn.
There is a way to tell exactly where your ruby nodes are. When you use a magic mirror to enter the Glacial Area, you spawn in a room with a portal. The layout of resources in this room tells you where your ruby nodes are located in the Hydrothermal Vents below.
- A weapons chest to the left side indicates that you will have a ruby node on the basin floor. It’s at the junction where the wall slopes down to meet the floor to the left side of the Divine Tree Control Room entrance.
- A cooking pot to the right side indicates that you will have a ruby node in the cave on the far left. The entrance is at the top edge of the basin to the far left of the map. The node will be at the bottom of this cave.
- Neither a chest nor a pot indicates that you have no ruby nodes, and you’ll have to come back on a later dive.
How to catch the ruby seadragon
In Dave the Diver, there is a small chance for a ruby seadragon to appear when you mine a ruby node. This requires a mining pick or a fully upgraded knife. Watch out for the fiery haze that surrounds the ruby nodes since touching it will inflict you with a burn.
Melee the ruby node three times (left-click on PC) to mine it. After you’ve finished mining, look out for a small red seadragon that appears in front of the node. It can be hard to see since you’re looking for a small, bright red streak on a darker red background.
If you’ve gotten your seadragon to spawn, catch it with your bug net (space bar).
You’ll have to return on another dive if there is no seadragon. It helps to make a manual save just before a dive, use the mirror to access the Glacial Area, mine for rubies, and then reset if you failed to get what you want. It can take many, many mining runs to get a seadragon to appear. It took over an hour of reloading the same save to get my own ruby seadragon. Just keep at it until you get lucky.
Once you have it, though, the ruby seadragon has excellent stats for seahorse racing. It might be better to use it for races rather than cooking it into a dish.
