GoonZu Online/Summons and Horses

Summons
You get to have a summon when your level 20 (use to be level 30 in Global Goonzu). Keep in mind that you do not need any capture skill to have a summon or a summon skill. Once you reach level 20 and would like to have a summon, go to a market or to a capture artisan to get a Evil Raccoon summon doll. Double click the doll and there is your new summon. Keep in mind that the doll sometimes fail so make sure you have a few ready in case the first one doesn't work.

Leveling
Every time you summon your Evil Raccoon, it gets a portion of the experience you get. So to level it, make sure it is alive and summoned. The summon also has a limit of time it can be summoned. If this time runs out, you will need to wait a certain amount of time for the recovery period before you can summon it again.

Horses
Horses and other mounts are summoned from medals. The Vixen and wolf are summoned from spirit orbs. Starting with  the March 5th patch, users who reach level 15 (after the patch) receive a brown foal. Its stats are already maxed out and it cannot be traded.
