Charging??? Homing effect???
Fireball???
Heh. Are those abilities limited to later versions of the game? I'm playing the version on Steam.
Here's a video of the boss fight where someone is using both of those abilities.
Granted, I just call it a homing ability. You can sort of see that some of the fireball shots have an arc, but the capability to connect with the target is limited. Still, I have found both abilities to be useful in my own game, particularly against this boss.
EDIT: I take back what I said upthread. Solomon Shrine and the surrounding canals are confusing and interminable. The amount of backtracking needed for all the macguffins to get to the next area make things much, much worse. I've enjoyed the game overall, but I'm quite ready to be done with it all.
