How To Get Mods Destiny 2
Some may have received a Taken Resist or a Fallen Resist mod from the Last Wish or Scourge of the Past raid, but these ones locked to just one race. Currently, the only way to get a Resist mod in Destiny 2, or at least the type that focuses on any enemy type instead of a specific race, is through the Reckoning activity introduced in Season of the Drifter. Players wager a mote at the start of the activity and then if the team is successful they receive a piece of armor in one of the four Gambit Prime armor sets. If they’re lucky, the piece of armor will have one of the mods on it. Destiny 2 players looking to grind for the Minor Resist, Major Resist, or Boss Resist mods will need to have luck on their side, though, since the mods are very rare.
How To Get Weapon Mods Destiny 2 Forsaken
Destiny 2 players have found two ways to reliably farm mod components (used to buy mods from the Gunsmith) that only requires a few basic materials and a little luck. To answer you specifically, mods of a similar type (say grenade recharge) do stack, but multiplicitavely, not additively. So a single grenade recharge mod cuts 5 seconds off that timer, but two would only cut it by 8 seconds rather than 10 for example.
Now if you ask me, the fastest way to level up right now in Destiny 2 is to do Lost Sectors. These missions are probably the fastest way to level in the game after the story. There are a ton of lost sectors on each patrol all being able to be found on the map, located by the two curved lines with the dot in the middle.
To complete one you have to kill the yellow health bar enemy in the cavern which opens up the chest in the back of the room. The chest will contain new gear, two tokens for the region, and 1000 glimmer.
