EGO Level and Weapon Mod Slots

[Razor]

Too late for me, I am already around 2k EGO and I only recently found out about this.

Thanks for the info though

Probably worth mentioning that as EGO increases:

Shields get better shield ratings
Grenades become more powerful
Bonuses on Weapons get bigger multipliers e.g. x1.05, x1.15, x1.25
The more weapons you level up, the more variety of bonuses you'll see, e.g. damage from above on a shotgun or damage from behind on a shotgun.

I think the next project would be to list all the available bonuses to each weapon from leveling them up and seeing if those bonuses' power changes with EGO level too.

I've noticed and had a look at the patterns behind nano types and mod slots somewhere along the line as well.

I do remember at hitting exactly 3250 ego rating that weapons in the shops changed from having 2 mod slots and a nano dmg type to 3 mod slots without any nano dmg types.
At 3625 (or 3675?) it turned into 3 mod slots with nano dmg, 4000 4 mod slots without nano dmg.
Can't remember the exact level where it turned to 4 mod slots and dmg types again.

Once I hit 4000 most weapons in the shops turned to ego rating 4000 (4 mod slots, no nano dmg) but some weapon types would still be below 4000. Think rocket launchers and some others stayed at ego rating 3750 for a while.

Once I hit 4000 and for a while after all the 4000+ weapons I got from drops still had only 3 mod slots. Not sure when that changed but think it was around 4100-4200 somewhere.
For weapon drops I'm fairly sure there is no relation between ego levels and nano dmg; no nano dmg or nano dmg is random outside the shops.
