The Chosen Ones

I find some stuff in Chapter 9 too easy, mainly: the fights against the death knights, the multi-colour crystal cave quest, the escort quest and the Axobada quest. My suggestions on how to increase the difficulty of these quests/fights:
- Death knight fights: Increase hp and attack, add more spells and events cause death knights, I thought, were suppose to be very strong such that they can kill Dragon Slayers.
- Crystal cave quest: Change the crystal to be destroyed into a new mini-boss that can use spells and cast events, one of which could be summoning of crystal golems. And when it is at critical hp, it could continuously summon golems, so the characters need to finish it off before too many golems are spawned.
- Axobada quest: Have several (like 10) random, independent electric orbs floating around the arena. If they touch a monster, it is healed to full hp. If they touch Fradz, they can deal high damage to him. Makes it more difficult to finish the quest and Fradz now cant just stand on one spot to kill the monsters.
- Escort quest: Have some ambushes by the golems or ancient creeps along the way, as the two NPCs are walking. So Galeoth need to tank the damage and quickly kill the monsters while the other NPCs are protected. When they are at the second cave, there could be a mini-boss guarding it, so Galeoth needs to fight and kill it to allow access to the second cave.
