[Silent Crusade] (lv105 to lv160 quest chain)
ADVICE: DO NOT USE YOUR SILENT CRUSADE COINS till chapter 3 is COMPLETED, which is available lv120 (the level 2 link skill level)!!! Complete chapter 3 for [Veteran Hunter] title eq (3stats 300 hp/mp), so that you have at least 255 silent crusade coins for the lv115 (+2wa/ma, +1 stats) silent crusade MYSTIC FACE equipment.
Silent crusade coins are earned by defeating NORMAL MAP boss monsters NEAR YOUR LEVEL, completing the quests, and also defeating chapter 1 (2 silent crusade coins per boss), chapter 2 (3 silent crusade coins per boss), chapter 3 (4 silent crusade coins per boss) and chapter 4 (5 silent crusade coins per boss) bosses. The entry limit to any Mystic Gate daily is 15 times ONLY.
4 Chapters, each having 5 bosses.
Final Title Equipment: [Superior Hunter] (in set-up inventory) +3stats, +400 hp/mp. (chapters 1 to 4 complete) https://www.facebook.com/mapleseafreebossruns/media_set?set=a.373956619366399.83586.100002561932116&type=3
(Title Equipment are not medals, they appear above your head, and title eq can be turned ON or OFF via the set-up inventory if you have them)
Chapter 3 can be completed at lv120 [Veteran Hunter] +3stats, +300 hp/mp, chapter 4 can be completed at lv140.
***IMPORANT things to take note of:
1. The Mystic Set belt is sold in the shop in the Silent Crusade headquarters. (Edelstein > enter the portal at the building behind NPC Bastille > go to the far right inside the building, and you will see a golden portal appear. > enter the golden portal to reach the Silent Crusade headquarters.
2. The bosses in "mystic gates" can be fought 15 times a day, and they drop silent crusade coins. (Chapter 1/2/3/4 : 2/3/4/5 silent crusade coins each.)
FOR THE BOSSES WHICH ARE NOT in MYSTIC GATES: Snowman in El Nath - Dead Mine(Map name: "El Nath : Sharp Cliff 3"), Richie in El Nath - Dead Mine(Map name: "El Nath : Forest of Dead Trees IV"), Manon and Griffery in Leafre give 3 silent crusade coins each. Manon's 1hp/1mp attack has much closer attack distance range, while that of Griffery is much wider attack distance range. Please stock up on potions which heal sufficent HP and MP, when fighting Manon and Griffery.***
AND THEREFORE, FOR THE RECOMMENDED BOSSES, WHICH ARE NOT IN MYSTIC GATES:
 Snowman in El Nath - Dead Mine(Map name: "El Nath : Sharp Cliff 3")
