Castilla Mine

Location:
Castilla Mine can be entered at the new location Castilla, Garrison 1 at H3. To get to garrison 1 talk to the castilla NPC at Port of Coimbra E7.

Entrance Fees:

This raid can be done with 1-8 families, and the first try for the day is always free.

Second and third tries need a ancient relic to enter, and for the fourth and fifth times you need 2 ancient relics to enter.

The enemies in the mission have low AR, but their ATK values are very high, and they don't miss all that often against high DR anyway, so the first few bosses will be quite irritating with their status attacks and the last few bosses will really hurt a lot with their skills. The best counter is to have a good set of racial weapons and a good mix of disabler (Stun, Freeze, etc) skills and weapons.

I'll just describe the bosses briefly:-

1. Ararat: Uses Fear and Drill skills. Summons mini Ararats which use the same skills.
2. Phobitan: Uses Atomic Crazy Rush and Dragon Kick skills. Summons various types of Phobitans.
3. Basilisk: Uses mental breath and laser attacks. Increases ATK and DEF dramatically when near death (the ATK bonus makes its attacks very likely to 1hko its target). Initial area fills with Celemantises and Imagos with Poison breath attacks over time.
4. Blink Dog: Uses Fear and Bite attacks. Initial area starts with many Demonisches with Sleep attacks.
5. Chrysalist: Sits in a pit about 4m away from nearest land, so it can only be hit by distance attacks, like Uraeus but nearer. Casts massive AOE attack which can 1hko ground characters with low-to-mid 60's DR (harmless for better equipped or flying characters). Initial area starts with several Fanatics with Fear attacks.
6. Golden Spider: Uses Knockback attacks. Initial area starts with several other types of Spiders with Web, Poison, and Knockback attacks.
7. Chimera: Uses various elemental skills and attacks. Summons Dreamblades. Initial area fills with Artic Dracane with lightning range attacks over time.
8. Argus: Uses usual mental skills and attacks. Increases ATK periodically. Initial area starts with several Rocks and fills with eggs which will hatch into Bribantras over time.
9. Skull: Uses various elemental skills (same as the one in Secret Temple). Initial area starts with several melee Skeletons.
10. Dekaravia: Uses various elemental skills. Casts Curse debuff (increase damage received). Casts Ancient Chaos debuff (affected characters randomly attack friends and foes, and also become targettable by friendly fire; effect lasts 10+ seconds). Permanently increases its own DR by 1 occasionally (this is stackable, and if taken too long to defeat, it can make its own DR go all the way up to 75+++, which pretty much makes it impossible to kill without super weapons at that point). Initial area starts with several melee Skeletons and fills with more range Skeletons over time.

Basilisk, Argus, and Dekaravia will each drop a Roulette Chest upon defeat, which rewards all families within the mission 2 random items each. These three also happen to be the most difficult bosses in the mission.Chrysalist will drop nothing.

Blink Dog and Golden Spider do not unlock any other boss and they do not increase mission time on death, so it's not necessary to kill them, although getting pass them without gaining their attention is a different matter altogether.

Secret Room:
There's also a secret treasure room with a free roulette chest and several treasure mobs, but you can't always enter it. When you see the "You have discovered the door to the ancient secret room" notice at the start of a mine raid, go to F2 of deka's room and detect/rouse/whole cancelation till a warp pops up.
