Granado Espada of Singapore, Taiwan, and United States servers are having the same Halloween event. However, the event NPC are located in different maps for different servers. As usual, Singapore server provided the best event article.
Read [Halloween Event] Sara's Bewitching! (SG). I will just add a few extra tips on this event below. See also 活動《萬聖節活動》公告 (TW) and Willow the Witch Needs Help (US). Thail servers are also having the same event. See Patch Update ประจำวันพุธที่ 26 ตุลาคม 2554 (TH). See also a Taiwanese player's event guide - 【官方活動】萬聖節活動.
The monster hunt quests are given only during even hours (e.g. 2pm, 4pm), while Haunted House mission is accessible only during odd hours (e.g. 1pm, 3pm). Only the hour matters, the minutes are not important. Both require a character wearing Halloween Pumpkin Hat.
The monster hunts involve a random monster, such as:
- 70 Little Plaque Etons (L25 Daemon) in Tetra Ruins
- 30 Visage Noirs (L32 Daemon) in Tetra Ruins Golden Road
- 70 Zombie Mermen (L41 Undead) in Porto Bello The Deck or The Cabin
- 100 Haunted Candles (L55 Golem) in Dr. Torsche's Mansion Savage Garden or Reception Hall
- 200 Sentinels (L58 Golem) in Dr. Torsche's Mansion Reception Hall
Haunted House is a solo mission for 5 minutes. Kill Hallow Apparitions (L100 Undead) for Spirit Coins (not tradable). They have very high physical defense (DEF 600), but low resistances (Lightning RES -50 • Mental RES 11). Thus, it is recommended to use magic characters, such as elementalist. The monsters respawn after a few seconds, so spam [Tenseness] or similar area skills, then loot the coins before the next wave. A single mission can earn you about 300-400 coins. Trade the coins to the witch for Halloween Boxes. See the article linked above for possible drops.
Note that pets can continue looting in the few seconds after time ran out and before you are removed from the mission map.
