-First is the disadvantage, this build has a very unstable duration index of only 95.5% so we will use 2 Crimson Archon Shard (Tauforged) which have an additional duration index of 10% (15%). This helps the duration index increase to 105.5% (115.5%), although not much, it will create more stability during Lich/Sister hunting. Especially when we replaced Banshee's 3rd skill with Harrow's Condemn because this is a pretty good skill at locking on targets.

-Next is a special disadvantage when casting [Banshee] skills is slow, for that reason we can use Amber Archon Shard (Tauforged) with +25% (+37.5%) Casting Speed. This will help this warframe not lose too much mobility when performing its skills.

-Finally, for the remaining 1 empty archon shard slots, you can choose the type you like such as increasing strengh, duration,.... it's up to you to increase the warframe's stats the way you want.

If you think this build is good, please give me a like, thank you
