how did this happen?

i was exploring a magma planet, when I opened a chest that contained this little gem:

notice the energy per shot: 579, but i only have 500, meaning that i can't shoot it.
is this normal?

 

Currently, yes. Guns are still being balanced.

 

Yes and no... the energy cost of that gun is consistent for something that does 5787 damage per shot, however, the DPS on that rocket launcher is unusually high (and is actually out of the asset's parameters for the current patch). Tier 10 Rocket launchers should now only spawn with a DPS between 1250 and 1375, so what could have possibly happened is that you landed on a planet that you or someone else had already visited on a prior patch and ended up finding a pre-balanced gun.

 

I found a legendary rocket launcher that inflicts over 3k damage per shot, and only costs 120 EN.

 

I have various rocket launchers as well with wonky values such as one that does 1.4k damage and costs 57 energy. These are all guns that I had found in previous patches. Energy-usage-per-shot is only based off of Damage per shot. Currently this is the unmodified asset for how EN consumption is calculated:

"gunLevelEnergyCostPerDamage" : ["linear", "clamp",
[1, 5 ],
[2, 3.5 ],
[3, 2 ],
[4, 1 ],
[5, 0.75 ],
[6, 0.5 ],
[7, 0.35 ],
[8, 0.25 ],
[9, 0.15 ],
[10, 0.1 ]
],

And here is a collection of a few common and legendary rocket launchers that have been all generated in the current beta version:



All of the guns are level 10 and are all within 1250 to 1375 DPS and have a Energy per Shot consistent with Damage Per Shot * .1

Anything outside these ranges I would not consider "normal" for this beta version.

 

Nice random generation of the gun! + 1 like!
