YMMV / Crystal Warriors

• Anti-Climax Boss: Emperor Jyn is surprisingly easy to defeat. He may have the highest stats of anything in the game, but he has no ranged attack, which leaves him vulnerable to being swarmed once his support is dead. Since he doesn't move off his castle until you get close, the enemy team is also functionally playing with 8 members vs. your 9... though, admittedly, four of those are Pyros.
• Demonic Spiders: Enemy magic users in general are a pain to deal with, since they can dish out heavy damage from a range where their victims can't fight back. Of them, Pyro is the most dangerous, since he appears the most often and tends to pack the most powerful spells... so, naturally, three of them show up in round 15, with support from other magic users and powerful melee attackers.
• Goddamned Bats: Bane can heal enemies and put your teammates to sleep in battle, letting him get in chip damage without any risk if he attacks first. However, due to his weak attack power, he's more of an annoyance than an actual threat.
• That One Level: Round 15 has three Pyros and two Sethes, which will bombard Iris with magic from behind cover and possibly finish her off before she can escape or be healed. Taking them down is difficult, since they're backed up by an Elite Mook of each element. The Big Bad himself is strangely far less dangerous, by comparison.
