"city where everything is epic level lich and even their servants are epic level liches!" is fucking boring. Congrats, owlcat, you magnificent bastards! You achieved impossible!
Already said hundreds of pages ago that ch 5 is too bloated even for me. I honestly was expecting a adventure like nwn: Hordes of the Underdark, where a monarch of the lower planes will be the main antagonist and only at very end after questing a lot, you will have a chance to face him and got a game where you see dozens of Godlike beings everywhere. I like high level stuff, but this game took it too far.
Sadly, enemies only does interesting stuff in beginning, like a ch1 conjurer using invisibility and spamming summon monsters but late game bosses never do something smart like it(eg - use a rod of greater quicken metamagic to cast disjunction in the PCs and then, CC the party). They are just mindless enemies with bloated stats mindless charging in your front lines. The first time that you see a skyscraper sized demon, is cool but the 666th time isn't.
Anyway, now that OwlCat adapted the "pathfinder's throne of the bloostone", their next game will gonna be less epic. BTW, most Adventure Paths aren't that high level. Skull & shakles only reaches high level(13+) on the very last book and 4 of the 6 books are bellow lv 10. IT is not a lv 1 to 10 adventure like you would prefer, but I'm pretty sure that you will like more any AP which OwlCat adapts next.
And lets pray, so Paizo will not act like Woketards and force OwlCat to "promote the current edition". After making a huge success by not following 4E trends, Paizo decide to .... Make bizarre admixture of 4E and 5E...
Illusion is shit until 4th level spells
No, are not. Displacement is a amazing buff which essentially
doubles the amont of hits which your front line fighters can soak. Mirror image is a amazing defensive spell. Vrocks uses it a lot in this game... You just lack offensive spells. And the point of illusionism is not to be a
pyromaniac evoker. IS to do illusion.
And as a low level mage, buffing party members > dealing damage. Even at mid level, you are more useful buffing.
