In Stellaris, using the right weapons for the situation can be the difference between winning a battle and losing it. So I wanted to make some notes about the three main weapon types.
|Name||Armor Effectiveness (S/M/L)||Shields Effectiveness||Weakness|
|Autocannons||Ignores 0%/10%/20% of Armor|
|Lasers||Ignores 15%/30%/60% of Armor||-20% Shield Damage|
|Mass Drivers||Ignores 0%/15%/30% of Armor||+33% Shield Damage|
|Missiles||Ignores 0%/15%/30% of Armor||+15% Shield Damage||Point defense negates|
|Torpedos||Ignores 50% of Armor||100% Shield Penetration||Point defense negates|
Note: This is current as of the Utopia expansion for the console version of Stellaris.
