Revealing The Infinity Tower
Seeking Treasure
A trapped furriend on top of a tower inCat Quest IIIis yourfirst main clue toward getting the Infinity Key. They will send you two pieces of junk treasure before asking you to check out a spot in the middle of the water in Coral Lake, which you may then get to andtest the water a couple of times. On a third attempt, you will suddenly get teleported to an island with the Infinity Tower. There, you will find out you need an Infinity Key to open the tower.
How To Get The Infinity Key
Cat-Face Mountain
At this point in the game, you will likely run into orfind the Cat-Face Mountain with three locks. This is the place that all of the Star Towers have been pointing to since you first landed on Pawt Purvanna. You will have todefeat three dungeons to unlock the towerand get inside.
The first is going to be theOrion Tower in Orion Ruins. This might be a challenging fight, as there are tougher electric-type cats to fight, and the game will suggest that you upgrade your equipment before entering. The boss in the Ghost of Orion has similarly tough electric attacks, but you will also get a couple of pieces ofarmor inCat Quest IIIon the way to the boss fight togive you lightning resistance.

The next stop is going to be theAntares Ruins Tower. You will have to fight the Seeker Antares, who has fire-based attacks. If you are properly leveled,bring some ice magic, and you should be able to handle this one. This will unlock the second chain on the tower.
Last but not least, you will have to face theCentauri Ruins Tower. Around Level 30 is probably around the right amount of power to bring into this fight. You will have to do some puzzling to open the way into the tower itself and fend off a few ships, so make sure to grab someship upgrades before heading over.

At this point, you canreturn to the Polaris Ruins near Cat-Face Mountain and take on the dungeon itself. This will give youthe Infinity Key and a ticket to the Meowtallica Concert.

Facing The Pi-rat King
At this point, you may go back to the Infinity Tower,taking on the Pi-rat King in the process. However, it is suggested you go through any other side quests and the Metallica Concert first, as some of the enemies and bosses inside are quite difficult, and Mewotallica will give you one of thebest weapons inCat Quest III. Not only that, but it is a series of waves of enemies, so there will not be much wiggle room for error.
Specifically,check out the Lovepurr Island Questand try to finish it first, as that at least gives you one of the only ways to heal in the game. You can check out how to complete this quest in the video by100% Guides.
Once you get the Tower’s treasure, you cango back outside and talk to Charon again. He will tell you about another secret in the tower, but you will have to find out what that one is for yourself. Then, you can continue your adventure to become the best pirate in the Purribean inCat Quest III.
