Invasion Build Help

https://mugenmonkey.com/darksouls3/215551

This is a one shot build that I'm sure has been done before, and I'd like some help refining it.

Questions:

1. Is it worth using old wolf curved sword and pontiff's right eye?

2. Is it worth using magic clutch ring?

3. Would lingering dragoncrest ring be a viable consideration?

4. Sellsword twinblades or gotthards? (Remember this is for invasions)

5. Is it absolutely required to have 60 fth/int if I want to you dmb or crystal magic weapon?

6. Thoughts/Other Changes you would make?
