Is it possible to make a heavy hitting Lich? Better description in post

So I am just getting into pathfinder and a buddy of mine has played for a few months so I asked him but he wasn’t sure. That he would ask his group but he has yet to get back to me so I wanted to ask a pathfinder forum. What I mean is maybe a fighter/necromancer dual class that becomes a Lich. Imagine fighting a guy in heavy armor and like two handed mace or sword that has the ability to cause diseases or summon undead and stuff like that. He’d be a power house in my opinion soo I was just curious. Thanks ^^

Hello,  The short answer is technically maybe.  I know that is very bland of a response. Though the reality of the situation. Content is often times limited by what the GM/DM and players in any giving campaign are comfortable with.. Or what fits into the lore. So, a build may be allowed to be able to be homebrewed if it isn't one which is easily accessible through the core rulebook. Just like a build that is available in the core rulebook. Might be off limits.  It is one of those things. Where you, the DM/GM and the rest of your party. Would have to sit down and discuss with each other.  Hope this is helpful despite it's vagueness and best of luck, William M.
