Currently, there is no use for the karma level system (aside from getting 10 GS every level you gain, or killing a pilot with +5/-5). I propose some additions to the karma level system that would give purpose to gaining positive or negative karma levels.
The only current level traits I know are for karma level -2, where police station turrets will automatically shoot you.
Additions for Positive Levels:
-At +1, 5% damage reduction from all damage taken by pirates or cartel pilots.
-At +2, ability to dock at Fort Vida (if this suggestion is implemented). Suggestion is here: https://forum.star-conflict.com/index.php?/topic/26501-fort-vida-elite-pilot-station/?p=313969. Aggro range of pirate turrets increased by 25% (to compensate for negative karma pilots being auto-targeted by police turrets).
-At +3, auto-distress signal. This signal will emit when you are attacked by a player, and will bring the nearest police patrol to your location (if there is a police presence in the sector), however, your aggro radius for pirates and cartel pilots will be increased by 20% (will bring your aggro range from 2.5k to 3k).
-At +4, ability to call in a police squad to escort you for a certain number of sectors. This ability could be a scannable item similar to a cargo drone, which will instantly warp in a police squad that will escort you for X sectors, however they will not escort you into the frontier sectors. (X could maybe be 4 sectors). The scannable object would be present at every warp gate, similar to a cargo drone, but once activated, it will have a 10 minute cooldown, and no escort objects will appear until that 10 minute window expires. (Police escort will only last 3 minutes if the user does not leave the sector).
-At +5, Alien bio-jammer. This passive ability will reduce the aggro range of aliens for your ship by half. This ability would make it extremely useful to travel through alien sectors without being detected or attacked.
Additions for Negative Levels:
-At -1, 5% damage reduction from all damage taken by police or transport escorts.
-At -2, ability to dock at Fort Muerto (if such a possibility will be implemented).
-At -3, pirates and cartel pilots will no longer attack you, however, police will automatically attack you if you go within 3k of them (if you are in a station sector, they will not attack you within 5k of the station, unless you have criminal status).
-At -4, auto-piracy assistance signal, when you attack a player that does not have criminal status, a squad of pirates will warp in 5k away from you to assist you in killing the target player. (The squad of pirates will grow larger the higher karma level of the enemy player. I.E. level 0-1; 3 pirates, level 2-3; 4 pirates, level 4-5; 5 pirates). The pirates will warp out of the system if you die, the target ship dies, or the target ship leaves the sector.
-At -5, Alien bio-emitter. This passive ability will fool small alien ships within a radius (maybe 3k meters) into thinking you are an alien and will make them help you attack a target. (This ability will only affect Infected Ships, Biomorphs, and Cybers, and a maximum of 4 aliens/cybers can be fooled at one time).
too lazy to say what.
