Aegis

A ship in A Pirate's Tale.

Quoted from the description from the shipwright(s), "The Aegis is a moving fortress." The Aegis has 10,000 HP, and a gigantic cannon on the top. The Aegis is a legendary PvP reward, with an 8% drop chance from said rewards. The Aegis also moves at 10 walkspeed, making up for the damage it can deal.

Gigantic Cannon
The HUGE cannon on the top of the Aegis is much like the ones you see in Stormwell Fort, except this one is actually usable. The massive cannon can hold up to 5 cannonballs, which come from a lower part of the ship. You collect the cannonballs and load them into the cannon, then click the fuse on top of the cannon to fire them. They aim at the direction the front part of the cannon is facing. The cannon fires like a repeater, firing all 5 shots at estimated 0.2 second intervals.

VS Kraken
Against the The Kraken, it stands almost no chance. With a properly commanded crew that's repairing and loading cannons, the Aegis can easily take out the Kraken. You'll lose around ~500 HP to your ship per swing, and with each swing the kraken does (with its tentacles) should be blocked by the Precursor Shield. You won't be needing to despawn the Kraken to glitch it, but if you wanted to, you could-- however, it would (overall) take a bit of time to get the Aegis to the Kraken, so be cautious.
