Here's is a list of all the ideas that I have ever had, which I will continue to update.

Battle Artifacts:

Unwanted Helpbot:
This will repair your ship whether you want it or not...
Repairs a disabled player with 1/2 their hull. Can only be used on someone who has performed an offensive action against you. Only one may be used on the target every 8 hours.
Dropped by Drannik NPCs? (they are rogue drones afterall)
---------------------------------------------------------------------------------------------
Dysfunctional Nano drones
These were defective models of Repair Nanodrones, but someone has found a use for them...
Deals damage directly to target's hull. Damage scales with target's rank. Can only be used as your FIRST attack on the player, and damage is dealt directly to the hull.
Dropped by Laluzi NPCs (they're the engineers aren't they?)
---------------------------------------------------------------------------------------------
RSL Power foci

Missions
Combat Training:
Ungrey requirements: Rank 100, 50 PvP kills. This mission will be non-terminating, but you will need 25 more PvP kills than last time to un-grey it again.
(Race), Your fighting skills are very good, as is proven by your record in the field. However, recently we have noticed you have been using our repair bay a lot. You need to sharpen your skills...

Reward per completion: heightened combat senses: give +10% attack and defence for a week. cannot be removed. Stacks with other artifacts.
---------------------------------------------------------------------------------------------
Harnessing the Singularity (Follow on mission to Investigating a black hole)
Using your findings, our scientists may have found a way to harness the sheer gravitational pull of black holes to reduce energy loss. Assist them with gathering more data and constructing a prototype.

Risks per round: Singularity pull (additional energy loss)
Two completions.
Reward on Completion: Ship module: Dark Void Power Generator
Size 20, +20 Energy capacity, -40 energy loss from relays
---------------------------------------------------------------------------------------------
Trade Embargo (follow on mission to Disrupt Trade Route)
Our efforts to disrupt our enemies' trade routes have only caused them minor problems. They are still receiving more than enough resources to keep attacking us. We must stop this at the source. Follow one of their trade frigates to their base, and form a blockade. Don't let a single ship leave.

Risks per round: return fire (mid chance for mid damage), Trade ship escapes (small chance, mission failure)
Chance to earn: Mass storage pod or Tessarect container (low chance).
---------------------------------------------------------------------------------------------
Trade Clearance
Ungrey requirements: Rank xxx
As a result our recent large scale battle with the rogue science league, the space near to our trade centre in sector T has become very dangerous due to all the debris that is floating around. The merchants will pay you very well if you clear the space for them. You may also keep anything that you happen to find.

Risks: Collision with space debris (minor damage), Damaged Weapon Malfunction (high damage), Damage to trade ship (costs you xxxxx credits).
Chance to find: CTP (1-5), damaged experiment (minor RP), Reactivated ship (random RSL uncommon or better ship appears on your BT).

---------------------------------------------------------------------------------------------
---------------------------------------------------------------------------------------------
Mission chain

Meteor Defences (follow on mission to Prevent Meteor Impact)
If it wasn't for your timely actions, we would have lost several valuable colonies. However, a greater challenge is ahead of us. Our scientists predict there will be a huge meteor storm in Sector M soon. The meteors you destroyed were only the start. Help us to develop some effective defences.

5-10 completions?
Reward on Completion: C.O.M.E.T (counter obliteration meteorite extermination turret)
Planet structure, Size 1, adds 100 defence and 5% attack bonus. Limit 1/planet
---------------------------------------------------------------------------------------------
Unintentional Benefits:
Intergalactic merchants are currently searching for a rare form of mineral known as astrodon. Initial analysis of the early meteors shows that their cores are in fact very rich in this mineral. We must not pass up this opportunity - help us develop a way to collect the debris from the meteors we will have to destroy.

Two completions
Reward on Completion: Ship module: Space dust Vacuum (on completion)
Size 10, +20 scan, +5% mining production to the planet you are currently guarding.
---------------------------------------------------------------------------------------------
Taking Care of the Competition...
With our vacuums complete, we are ready to take full advantage of the meteor storm. However, some of our rivals have heard of our plans to collect the debris. Give them a friendly "Warning" to stay away, or else.

Risks: Return fire (minor damage), diplomatic problems (small chance of mission failure)

5 completions?
Reward on Completion: Battle with astro-miner (matched ship, drops mineral hold which grants 8 hours of mineral production)
---------------------------------------------------------------------------------------------
Reaping the Rewards
The storm has started, as predicted, and with no competition there will be a LOT of minerals to gather. Keep an eye out for the astrodon cores - one merchant claims he can fashion something special out of it if he gets enough, for a small fee of course.

Risks: Stray asteroid (heavy damage)
One completion

Playable Races

Infernites
These fiery creatures of destruction arise from the cores of the tortured, daemonic worlds, eager for war. They were imprisoned long ago, but have somehow broken free, and will stop at nothing to take their revenge on the galaxy. However, they are also very organised and wise, and have managed to work out how to salvage and enhance space ships. They understand the importance of superior defence as well as attack. They hunt in swarms, as there is a great strength in numbers.

+20% attack and defence

Allows the player to decrease a planet's size by 1 for 200 energy every 60 hours. Will only be available if a) you own the planet and b) there is enough "free space" to lower it by one (you have to remove structures). If the planet is "Very Tiny", then using this ability will destroy it, removing it from everyone's databases and abandoning it.

NPC Races

The Swarm
The Swarm are a collection of rogue nanodrones. Individually, they are no bigger than a Konqul's fist, but they hunt in massive swarms, devouring stars to quench their thirst for energy.

---------------------------------------------------------------------------------------------
---------------------------------------------------------------------------------------------
King of the Hill Planets (Like Exotica)

Bricket:
This planet's is made entirely out of solid clay, a result of it's dangerously close orbit to the nearby star. The surface is completely uninhabitable, but just below the crust is very rich in minerals
Average size
20x Mega Rich Mining. No other resources.
Passive 10,000 defence.
1000 population.
NO non-production structures can be built on it at all.
Immune to all artifacts.
---------------------------------------------------------------------------------------------
Astorbit:

Massive Size
10x Mega Rich Mining and Artifact, 30x Mega Rich Research.
Passive 5000 attack.
400 Population.
No attack structures may be built, and no ships are able to guard this planet due to the immense gravitational pull of the core.

Immune to all artifacts.
---------------------------------------------------------------------------------------------
Pulsoron
This strange, tiny planet seems alive, and often emits bursts of an unknown energy form. This energy may be containable, but it will be dangerous...
Tiny size
No resources, but gives you 2 hours worth of energy extra every hour (so if your charge rate is 30/hour, you'd get a bonus 60 energy with your delivered productions)
200 population.
Every 12 hours, one of the following effects will randomly happen:
Flare: For the next 4 hours, the energy bonus doubles.
Flux: For the next 4 hours, the energy bonus halves, but the planet is immune to all attacks.
Storm: For the next 4 hours, one structure is removed at random every hour, and no new structures can be built.
Aura: For the next 4 hours, any ships that attack will have their attack doubled but defence halved.
Pulse: All guarding ships are removed, disabled and cannot re-guard the planet for 12 hours.
Purge: The population halves, and the population rate drops to 90% for 12 hours.
Immune to all Artifacts
---------------------------------------------------------------------------------------------
Any thoughts?

I will continue to update this top thread as I have new ideas.

I don't remember the last time I saw a lazuli NPC.

Lazuli factory complex and ionic cruisers are two off the top of my head.

lol yeah once you get to like 180? i think iconic battleships are one of the main NPCs for that level range. those are the 'golden levels' where you can npc hunt undisturbed by annoying npcs like flamehawks for about a couple hundred levels. theyre a 4 shot kill (for me) and rather easy like most other npcs in that range.

I like the idea of:
Evasive Surge
Dysfunctional Nano drones

Just a note, the NPCs that drop these are only potential - please suggest a better faction to drop them if you think it would make the ideas better.

The First one is the only OK one i see there, we have a Ability that you can have that lets you flush all NPCs every 8 Hours, you have to do a mission chain to get it though requires EM.

id like to see something that increases the artifact of a planet by one and is an npc dropped arty

reason we had Taltherian from beginning

yes but they have a planet data optimiser and the new race will probally increase research, we got the mylaria and the toxic purifyer so I see no reason why we can not have an artifact to just increase artifacts

huh wha? we got malaria?

Some are good

Which ones? And could the others be improved?

Here's another one:

Quantum overdrive blast:
Halves a planet's defence and attack for 24 hours, and negates all beneficial effects on the planet.
CT lab creation - 50 ion storms, 50 EMP spheres, 50 disarming bombs, 50 quantum flares.

Overpowered. 20% on each. 25 Ion Storms, 25 Quantum Flares, 25 Containment Missiles.

That is how I would balance it.

Another one:
Drone fleet bay
Ship Module: size 30 Attack 150 defence 150, limit 2/ship
CT lab creation - 50 ship bots, 100 repair nanodrones, 50 Drannik saboteurs, 50 sentry guards

Disruptor Cannon - Attack +125 - (c) 4,500,000 - (Pawlacite) 18 Size: 30
Inertial Dampener - Mark III Defense +66 (c) 58,000 (Darrinyte) 12 Size: 30

Given that this is a special item aimed at higher ranks, that seems about right.

And another:
RSL Power foci
Adds 20% to attack power for 2 hours. Cannot be removed by effects. Stacks with Crimson Obelisk and Ancient crystal foci.
Occasionally dropped by RSL siege cannon (to account for the 50 RP you get for a LOT of work otherwise).

Keep 'em coming, you have good ideas.

Thanks. I'll update the top post as and when I get new ideas.
And are you stalking my thread Thunderbolta? You seem to respond within minutes of me making a new idea
