There is a fairly serious error in the Bosses section discussing Lilith. Where you confront her and Mestan, it states in the Bosses section, "Simon's Unified Strike has a 100% chance to inflict Blind, Silence, and Stun. Use this on Lilith turn 1."
It does NOT have 100% chance to inflict these. Lilith resists all three. In three attempts, I only managed to land Blind once. So, is this an error in the coding of the game, because clearly this tactic does not work? Either that or the main walkthrough is wrong.
