I thought I had asked this before, but what about preparing metamagic on an SLA or other factotum abilities require houserules? Plenty of things basically require 3e to have house rules (thought bottle, incantrix, etc), but I don't think factotum is an offender. I'm interested, though.
A cursory search of this thread shows no one talking about metamagic requiring houserules, so I'm going to assume this is directed at me.
I'm not claiming that the metamagic being applied to SLAs requires houserules (it may or may not, but I haven't looked at it).
What I'm saying is that the Factotum's entire inspiration mechanic is garbage writing that requires houserules to function at all, much less in a way that wouldn't cause the entire game to become literally the dumbest thing ever.
I mean, by RAW, you rest for 8 hours and then wake up, and prepare divination, how much IP do you have? And if the answer is "It depends on what you did yesterday afternoon" do you see how incredibly dumb that is?
Next step, you walk up to a locked door, how many IP do you have now by RAW?
Next you find another locked door, how many IP?
Then you leave the town (because you were just wandering around town) and go to a dungeon an the door is locked, IP?
Then you run into a monster, IP? Then the monster getting murdered alerts enemies some of whom run through the complex alerting other enemies and some who come straight into the room and fight you, IP?
Finally, after murdering everything in the complex, the party rests, and you wake up tomorrow, IP?
And how are any of those answers RAW and not "just whatever I feel like, because the Factotum class doesn't give any fucking direction at all on when the Factotum gains IP."
And even if the Factotum class did give any fucking help at all, you'd still have a bunch of Factotums just storing up larger and larger piles of IP and/or bag of rats/locked door tricking themselves into unfathomably huge piles of IP so that they can defeat the BBEG with 847 consecutive standard actions from banked IP.
