It's very simple, you only use as many boosters as you have energy for.

Thanks Sasaki, I was able to do it based on your post. Although only in the live client, not in the dev client, which will make things a bit harder to debug.

First, I think the difference between invulnerable and not invulnerable can be called a change. (And let's not forget the fact that it wasn't invulnerable in the first place since its accumulator could be drained.)

Second, it's been like that for almost 2 months and noone said a thing. Quite the contrary actually, some people even said that the hit size reduction bonus is useless and it would have to be more prominent to have an effect.

But let's see:

Basic robotics lvl 10, the T4P evasive module, and the evasive nexus at lvl 10 brings 3 down to 0.25, that's correct.

What can you use against that beyond draining its energy:

* Any light laser's hit dispersion is 3
* Precision firing lvl 10 makes that 3*(1-(10*0.03))=2.1
* T4 weapon stabilizer brings that down by 15% to 1.78 (using 2 means 1.52, and using 3 means 1.29)

1.78 dispersion against a 0.25 hit size means ~0.14, which is a 14% chance to hit (16% with 2 stabs, 19% with 3). (Or in other words: every 7th (6th, 5th) shot hits on average.)

That's for a robot which has been designed to have evasion as its main defense.

ps. I realize there is a discrepancy between modules and extensions modifying turret dispersion and hit size, some using linear reduction, and some being percentage-based. They should be made consistent either way.

The Vektor will be fixed soon. I simply forgot about the extension that boosts the evasive nexus. (Btw it's -0.20 with everything maxed and T4 modules.)

The dispersion/hitsize gap will be widened around the last wave of robots. Until then I'm keeping myself to the current status quo. I want to keep my sanity and don't mess up everything midway.

Message from our server hosting:

There was a bug with this, and it's working a bit different than what the patch notes said.

From now on every morning at 8:00 server time, artifacts that are older than 3 days will be deleted and new ones will spawn.

(patch notes updated)

Plants grow randomly, there is no connection between their death and spawning.

As for minerals:

They were never meant to be better than Mk1, the intention was to be on par with Mk1. (At least those that have a counterpart in other factions.) If you only drive Mk2, they are not for you.

This was a change in 3.7.4.
