Eggyhead bossfight.
Eggy has 3 phases, and 4 cutscenes.
In Eggy's 1st phase, his attacks deal 150 damage - 25% of whatever your current defense is. In his second phase, attacks do 225 damage -25% of your defense. Third phase, 400 - 15% of your defense.
Eggy has 18000 HP in phase 1. 25000 HP in phase 2. -1 HP in Phase 3 (I'll explain why).
Eggyhead in phase 1 thinks he's just sparring with Wymar, and doesn't know she plans to kill him. Eggyhead can be flattered with compliments and/or flirts in order to spare him. In phase 2, Eggy realizes Wymar is attempting to kill him, and is not holding back. Eggy can be spared at anytime during this phase, as Eggyhead is trying to get Wymar to stop. In phase 3, Eggy is supposed to be dead... But he won't die. Eggy is determined to help Wymar snap out of whatever is controlling her, no matter what. Hitting Eggyhead will do no damage, and the only way to stop him by trying to apologize and beg for him to stop, multiple times (ten times each for both actions). At the end of the fight, you have the option to spare or kill Eggyhead. Sparing him results in him giving you a set of armor and a portal to your next destination. Killing him results in him dropping Eggs-calibur (his sword).
