All but the Navy Bastion can be found in events known as the EITC Fleet. They are extremely powerful, and are dang-near impossible to do alone ( But COULD be soloed ).
The Test Server is where some players go to try and test new updates before Disney releases them to the public.
New ships are out, guys! They belong in what is known as the Treasure Fleet - the Navy equivalent of the EITC Fleet.
HMS Invincible
Lv79-81 Ship Of The Line
Uses: Round Shot and Explosives - extremely powerful, and I'd say more so than the EITC SOTLs.
HMS Victory
Lv79-81 Ship Of The Line
Uses: Roundshot/Firebrand.
Navy Elite
Lv69-71 War Frigate
Uses: Roundshot and Firebrand
Your basic equivalent of the EITC Tyrant, although the name is a little more plain - at least to ME it is.
