Malek is killed offscreen in a cutscene, but you still pitted against two magicians at once. Not a bad idea, although the Druid just places water puddles, which is hilarious. I suspect that they rolled those bosses together due to time constraints, since when Kain brings their “mementos” to the pillars, he repeats “and the pillar accepted” three times in a row.
Because there’s no experience or currency in the game, fighting enemies is just a waste of time. Moreover, the further you get, the more annoying the enemies become, often stunlocking Kain with ranged attacks or poisoning him, while there’s a limited number of antidotes available. Kain has magic shield that completely negates ranged attacks, and mist form that ignores most melee attacks and floor spikes. Both require mana. If you don’t have mana, it’s best to wait around the corner for it to replenish, since enemies AI is lower that ghosts from Pac Man. They would literally try walking towards you through a wall.
The boss of the cathedral, Azimuth (sic!), is terrible. She fires homing missiles that have a knockback of a missile, and teleports before you even manage to get close. You just need to get lucky to hit her with the Soul Reaver, which you also get in the cathedral.
I found a way around slow menus: you can set CD-ROM speed to x8, which improves it by a lot. Setting CD-ROM to x16 breaks the game, though, menus stop opening altoghether.
