Need help creating Nightblood off warbreaker for Pbp

[Darkwing_DM]

first i want to say I am sorry if this is the incorrect place.

My plan is to create Nightblood for my Monk in a campaign. this is the guideline I am following using a monk with bonded item using a combination of eldritch heritage (Vestige sorcerer bloodline: bonded item) and recruits/leadership feat (intelligent item option) the idea is to follow Warbreaker where you take the sword and throw it into the room let it beguile the enemy into picking it up then Ego conflict with the sword. I am also open to other ways to do this (most notably black blade arcanist, magus, or phantom blade archetypes. but I figure it would be harder because I think you need it to cast spells even though I cant find references.) the character and the sword will be LN, (to prevent alignment issues to simplify things but both will have different ways to achieve goals, thus the detect evil even though its a neutral sword.

I want the following but I cant figure out the cost and ego. (this is my first attempt with messing with intelligent weapons and I want to do it right.)

Vicious adamantine +1 bastard sword. (detect evil at will or 3x day, beguiling gift 3/day)

I would also like answers to the following that is causing the conundrum to do this.

1. is a wizards bonded item easier to add intelligent item properties? (cost wise)
2. do you add the effects Vicious, adamantine, first then go on the intelligent item chart to figure up the rest (through strictly bonded item), then add it on? Or is it easier to do #3?
3. Leadership/recruits feat (intelligent item) what is the stating Ego, Int, and Chr. if you take that route? or can you just pay the cost and not take leadership?
4. is there any other easier way to do this?
5. what is the lowest level to do this?
6. when you temporarily enchant your black blade as a magus does this boost the ego?
7. can you think of any threads where someone did this (or something similar), where I can look at it.

Thank you for the input.

Based solely on the information you've provided, your item has an Ego of 5 and a value of 13,935 GP (2900 of which is for the Intelligence). This is assuming base ability scores, since you didn't mention raising those. Those would up the ego and cost as seen on the chart.

Intelligent Item effects are determined differently from special materials and enchantments. You probably wanna give it some form of communication, though, because right now it can't even talk. XD You can just pay the cost and not take leadership.

Wouldn't Nightblood have something like confusion and/or terrible remorse spell-lke abilities? Beguiling gift doesn't really fit, you could just chop up a table or cut the heads off nearby daisies to use the sword. The ego the sword would need to have a noticable chance of taking over is ridiculous.
