That "last level" was suprisingly easy. Only thing that was stopped me (not for long) was precise jumping that i had to do there and there (Boots of Speed were very helpful) and little switch hunting- the thing i'll admit i "disliked" first Hexen.
After blasting everyone to kingdom come, finally i stood in Eidolon's Lair, resupplied stuff and into the fray.
And you know what? Eidolon was easier than i thought, despite his lightning orbs HURTS as heck.
I gave him a "War treatment" (read: Meteor Staff with Tome of Power, with one Krater of Might if needed). Ever power-up from Chaos Sphere couldn't save Eidolon from demise. Even Corax (from "Hexen") put up more fight than red devil.
Main game ended, but i have somehow to obtain "Portals of Praevus".
