[quote] Step 1 = Obtain an Exotic Weapon. Buy one from Xur, buy a legacy engram from Xur, 3 of Coins for it, do an exotic rewarding quest, or just get an exotic from doing strikes/crucible. Getting a year 1 from old raids works as well if you wanna jump straight into those. Step 2 = Buy an Exotic Weapon (Preferably Heavy). This requires 1 Exotic Shard and 2500 Glimmer. That single exotic shard you need could be gotten from any 280 Exotic you currently have, which might as well be capped off and broken down since you could just buy it again at the same level. You could also get it the same way as you got the previous exotic weapon, just for dismantling purposes. Any piece of armor works just as well so~ you've got options. As for glimmer, even more options. Personally, I like raids, as each of the old upgrade materials are worth 200(weapon material)~250(armor material) glimmer when turned into the speaker, and it's a nice break since they're hardly done anymore which makes it less of a drag to do. Outside of that however there are of course strikes for engrams/glimmer items. You can use glimmer items for specific enemy types or use the ghost corresponding to said item in order to get glimmer as well. Step 3 = Use a telemetry for said weapon type, or wear a class item with a corresponding perk. Just tell the Gunsmith I said hi, or get a cool class item and skip the 5 weapon part/250 glimmer cost. Step 4 = Use Motes of Light until said weapon has reached maximum XP, however do not upgrade it. The raids double for motes, netting you 15~20 per run, but I feel glimmer is harder to come by. The easiest way I get motes is simply filling my "XP" bar, dismantling junk, and random loot drops from either events or cryptarch. No shortage of ways to get motes really, most of the time you can amass them just by doing other stuff you'd already be doing. Step 5 = Dismantle the weapon to obtain 2 Exotic Shards, some glimmer, and a few motes. A tiny bit of a refund, + our reward. Now get out there, amass your stock of shards, and purchase/infuse those exotics! [/quote] If possible, use this strategy on a Year 2 heavy weapon, with either Heavy Telemetry active or a Class Item that increases Rocket/Machine gun upgrade rate You're welcome
