Dystopia

From what I understand reading this thread, if instanceA goes down, any images hosted there are lost, while the comments will still exist because they're federated. You're only shifting the responsibility of hosting the image from a site like imgur to the home instance of the poster.

I guess it comes down to if you're concerned about how long your home instance is going to be around for, use an external host, or see if/when account migrations are added if images move too (although they would also have to fix the src for wherever the image is now being hosted)

While not an weapon, the Kuva Kohm is a pretty good weapon with Innate punch through and is more heavily slash weighted. It does burn through ammo fairly fast though so an ammo mutation mod is a requirement, at least it's a Kuva weapon so you can easily fit a mutation mod into the exilus slot.

It also has very good status chance so Galvanized Aptitude ramps up fairly fast.

The extra crit damage and status chance from hammer shot probably help with procing slashes with the weapons base stat distribution. I would mostly treat that as your option slot. Other options would be Shred (weapon feel + slight increase in damage/shot if you're able to hit multiple enemies with the same shot), a fire rate mod like Vigilante Ferver (weapon feel + set bonus), Bane mod (largest increase in damage but somewhat annoying to use and not all enemies have a Bane mods that works on them).

You could play a frame that does multiple rolls like Wisp so that you don't need to change frames as often.

For spy as long as you are in the air ( and not firing a weapon) you are invisible, your 2 can be used to bypass lasers and your 3 can blind enemies, although I rarely use that ability for spy. Do not use shock motes in spy, they alert enemies.

Support/minor damage boost using haste and Health motes for most other missions. I'll usually avoid using shock motes unless an objective is taking a lot of damage, Breach Surge is usually better.

Replace her 4 with anything you want. She is mostly a Health tank that buffs mobility and "weapon handling". A good general support frame and the only thing wisp doesn't really do is nuke a room.

I would drop either Serration (most likely this mod) or Hunter Munitions and replace it with Galvanized Chamber. Serration, Arcane Merciless, Galvanized Aptitude and your + damage Riven stat are all Additive to each other so you're hitting diminishing returns. If you don't have issues landing headshots, Arcane Deadhead might be a better choice for the reduced recoil, easier to maintain buff, and increased headshot multiplier. Stick with Merciless though you prefer the faster reload/transformation.

Hate does not work, known issue and they're planning on fixing that later. Currently the only melee weapons that work for that challenge are Innodem and Praedos. Also Laetum, Phenmor and Ferox are the only guns that work currently for that challenge.

Doesn't really help you now, but for future reference, a lot of the Tenet weapons have innate Radiation, or there's a chance you used a Progenitor which gives Radiation as a bonus element (a lich with a Radiation Progenitor also has magnetize as one of its abilities. And an Impact Progenitor can spawn a sister with Hallowed Ground.

Most likely, someone on your squad was getting Rad proc'd or Magnetized and killing the resto of the team because of the base Radiation damage on the weapons or an ability like Hallowed Ground giving your team that status effect enabling friendly fire. You can bring a warframe like Oberon for status immunity with his Hallowed Ground or Nezha with his Warding Halo Augment to give the entire team immunity to Radiation Procs. To get around Magnetize you can use melee instead, I'm unsure if rolling lets you escape the same way it breaks you out of Malice's void bubble. Other than that, solo with a frame that can go invisible and hit it with melee until it dies, generally Sisters do not do much damage and deaths are caused by teammates that have been Rad proc'd.
