This guide is based on
Apophis' guide and gets some further explanations.
In most MMOs you don't have to capture and tame a mount but you want to get yourself a good steed in
Black Desert Online for it'll greatly help you in the game.
There are 2 ways to get horse: directly purchase and capture. If you have enough gold, you can purchase one from the market for temporary use, because capturing horse in the wild isn't easy.
Now in order to be able to tame your first wild horse you will need:- a capturing rope (aka lasso) that can be purchased from a Stable Master (see step 3);
- a few lumps of raw sugar (obtained from crafting, see step 1 and 2);
- taming skill at least level 5 (you can level up this skill by just riding your donkey).
Step 1. Search for a Food Merchant/Farming Merchant/Tavern Manager to purchase the materials needed to craft the lumps of sugar (you can easily find these merchants by activating the magnifying glass, near the mini-map, and selecting the food filter).
Once you found the merchant, buy cooking water x 10, and raw sugar x 100 (these are the mats for 10x lumps of raw sugar, as you will need several of them until you get used with taming).
Step 2. Press R to open your crafting menu, select the heating option, and right click on your cooking water and raw sugar to start crafting.
Step 3. Search for the Stable Master (same as the above, go to the magnifying glass, and select the horse filter that will show you the path to the nearest stable master) and buy 10 capture ropes.
Step 4. Go to our partner site
http://www.blackdeserttome.com/, click tools, then click the interactive map, and deselect all of the filters besides Capital, City and Horse and you will find several locations where wild horses can be found.
Step 5. Put the rope and the sugar lumps on your hotbar. Aim towards the horse and click the hotbar button for using the rope. A mini-game will start and you will have to spam the spacebar. After succeeding you will need to slowly walk towards the horse by pressing the “W” key. The spacebar mini-game may start again, so just repeat the process.
Step 6. After passing the mini-games, and arriving near the horse, you will need to feed him the sugar lumps (give him at least 4 lumps). Then you will have to press the “R” key and try to mount the horse. If you fail the horse will knock you down and you will have to restart from Step 5. If you succeed you will be able to ride the horse.
Step 7. Return to a Stable Master, access the "register a horse" menu, choose the horse you just tamed, and click register. A window will pop up where you will be able to name it.
Some important tips:- It's recommended to use the rope when the horse slows down or is stuck in the environment, otherwise you have a high chance to miss.
- Each time you use a rope, the effect of raw sugar lump will be removed. You have to consider using raw sugar lump again.
