In certain quest dungeons enemies have a chance of using skills instead of a regular attack. These skills have different effects and can increase difficulty in battle. These effects will be summarized here. For specific details on skills used in a specific quest, please refer to that quest page.
Enemy skills were first introduced in Version 1.0.7 with Ancient Shrine Hill's Ark.
Some enemy skills must first have a requirement fulfilled before activating. These requirements are usually either: the enemies HP is a below a certain mark, or a certain number of turns have passed. For example, in Palace of Underground Agartha Amaymon can only activate his enemy skill Berserk: Gore if his HP is less than or equal to 25%, and he can only activate Berserk: Complete after 41 turns have passed. An enemy can also activate skills in an order, as seen in Nightless Nightmare [Remake] were Walpurgis will follow a list of skills when her HP is is less than or equal to 20%.
However, instead of following a predetermined list, an enemy may also activate a skill at random. In Utopia Avalon [Remake] Arthur has a 20% chance of activating one out of his four skills when faced with HP≤100%.
Note: The only skill that does not need a HP or turn requirement is a preemptive skill. Preemptive skills will be used in the beginning of a battle, before the player can make any moves. They can be only activated once and have vary in effects.
