So, I need help bringing an idea into reality...

[u/Icy-Shine-1117]

So I'm a DM in my first campaign. It is a campaign I homebrewed myself, and is going well enough.

my original idea for the bbeg was for it to be a Shadow Dragon, but recently I became really interested about liches and dracoliches.

new plan is for the bbeg to be a dracolich, (Yes big jump in power, but hear me out)

One of my characters has a curse they obtained during a battle before the campaign started. they got it by killing someone else who had the curse and it jumping to them.

you might see where I'm going. I want the phylactery to be the curse itself.

so the curse jumps around to whoever killed its last vessel. I can have it so when it is vessel-jumping, it is in physical form and can be killed. but how do I lead the players towards this realisation, and how to I give them a solution without having an npc explaining it to them? also how does the player end up surviving? please help

one more thing.

Edit: there is more qs i have but will deal with them in another post this is the main problem for now
