Ellydium ships are more or less “endgame ships”. They require lots of investment and intimate knowledge with their respective ship types and roles.
for new players, I’d recommend progressing down the normal ship trees. Try out new varieties.
the way I see it it this, the normal ship trees are there for you to practice, to get used to what this ship role could do and should do. The “new” unique modules can add a bit of spice to the mix.
Ships from different factions may differ considerably even if they are the same type. For instance Guard frigates from Federation is quite different from those of Jericho, Command fighters of Empire and Jericho often carry different sets of modules.
Next up would be the manufacture ships, including R15s, R16/17s, a couple R11s and a couple of R10s.
R15s were the first manufacture ships to come out. They have 9 slots that you can freely choose, 3 slightly different F modules to choose from, a set of level 4/8 bonus to pick.
R15s don’t have ANY unique module, they can only use the common modules for that particular role. They require you to know what this type of ship needs in its build in order to plan the modules effectively. In terms of modules and bonuses, they don’t differ much from the normal ships.
Most R15s are quite good, though would pale in comparison with some of the top tier ships.
R16/17s are more towards the higher levels. They require you to have Pilot Level 15/16 and above in order to unlock the missions that give their blueprint caches (sure, you can buy them, but some tend to be expensive).
They have very unique F modules, and more often than not, the entire ship’s build is centred around its F module and unique weapon and modules.
say for instance, a Wolfhound gunship, its unique F would not only increase your speed and fire rate, but also fire out a volley of homing missile barrage. A favourite among my friends is to use this in conjunction with secondary missile Firestorm as a blitz attack.
This comes at the downside of not able to choose the slot arrangement and the level bonuses. But I call that a small loss, so far most R16/17 have reasonable slots.
R10/11 are “event” ships, meaning you can’t get their blueprint outside events. They have 9 slots that you can pick, level bonuses also chosen by you, and their own unique weapons and modules. Downside being, of course, that the events tend to happen only once per year.
