Create a new item for mount:
•	Type: ITEM_UNIQUE;
•	SubType: USE_MOUNT;
•	WearFlags: WEAR_COSTUME_MOUNT;
•	First limit field: LEVEL (if you want to need a certain level to use this item);
•	ApplyType(s) field(s): Add bonuses to the mount;
•	Value0: 525600 = 365 days (is REAL_TIME);
•	Value4: The vnum of mount who you go to ride (example: 20115).
•	Value5: If you want to see an special effect when you wear the item (if 0 or if value inserted not exist, will not show any effect, those effects is from SE_EFFECTNAME -> Special Effects).
•	Also I recommend to check the item_proto.txt from this archive to understand others.

Option in CONFIG:
•	MOUNT_MAP_UNALLOWED: index of maps where you want to can't mount.
