Editing MasteryTips

*MR9- This test is easier if you use a gunblade or glaive for ranged melee attacks, and Banshee, for her silencing passive.
*MR13- This test is easy with Titania. The first thing you do is eat a large energy pizza to give you plenty of power. Then fly around, shooting enemies, ignoring the platforms.
*MR23 - This test involves running next to control points without getting killed. If you use Limbo, he can jump into the rift, and become immune to enemy fire. After that you can just ignore them and run alongside the control points.
*MR26 - This test is like the MR 23 test, only it involves a lot more vertical movement, and having the control points moving from island to island. You can do this with Limbo, but I found it easier with Wukong. I gave my gun to the twin, to shoot the enimies, while I deflected their bullets with my sword. When the control point went across a chasm, or went up, I switched to Air Walker, which let me stay right beside it.
*MR28- To beat this challenge, you need to be able to group enemies together quickly, so you can make them vulnerable and kill them. Nidus' Larva and Vauban's Bastille work really well for this. I also equipped the Preparation mod, so I would start out with maximum energy, and not waste time on an energy cookie.
*MR 30 - This is a survival mission, which means that killing enemies quickly is important. One quirk of the level is that you have unlimited ammo. I went with Wukong, with a fast melee weapon, and the Bramma equipped by the clone. At the end of each wave, you'll encounter a set of "boss" enemies, including a nullifier, so you'll need to be able to kill them without using abilities. (Also, celestial twin's immune to the nullifier, so it can kill him pretty quickly.)
*MR L1 - This is a harder version of the MR1 test. You'll have to kill enemies using only your primary weapon, without using any warframe abilities. I went with Nidus for his high armor, and self healing passive.
