In the chapter where you play as Peter Jacobs, the boss you fight at the end. i can't beat him. i figured out that you shoot the three "balls" that he fires at you (or dodge them) and then fire a three point magical attack at him. what i can't seem to get is... in the next part, when he "closes" the space that you fight in, and the he summons the zombies to come at you, how can you cause him pain? i can never time it right. i've only been able to make him "flash" once, but by the time i finished casting the attack spell, he is not flashing anymore and my attack is wasted. any ideas on how powerful the spell should be here in the second part (can i get away with a 3 pointer, or should i up the ante and go for 5 or 7?)

thanks

You still have to use magical attacks to hit him when he flashes. You just have to time them right, you can't wait until he starts flashing.

Usually around the time the last zombie pops up works good for a 7 point one, which will end that round in one hit. Wait a little longer if you want to use a 3 point as it casts quicker. It will take three hits with the 3 point one.

There's still one more round, but it's more of the same, just no zombies. Just wait for the boss to wear himself out swatting at you (or whatever depending which alignment you're on as there's a different boss for each one) he'll hunch over the, nail him with a 3 pt spell. You can do a 7 point one again, but it's a bitch to get the timing down.

do i need to use 7 pointers on the guy, or can multiple 3 pointers get him?

It takes 3 3-points, 2 5-points, or 1 7-point to take you to the next stage
