Best BMIS to use
There are loads of BMIs out there, and loading them all on one horse is great but costly. The full description for each BMI is under Profiles, so if you want to get the full description look there. So, the best BMIs to use while training are here:
Nyx Pack: This costs lots of passes, but considering the items inside I think it's a real bargain. The M. Arms means you don't have to use Aging Points, the P.Stone means if you make a mistake your horse won't die and you can keep it forever, and the C.Timer reduces training time hugely. Even better, it comes with Nyx's star, letting you wake your horse up earlier, therefore training it quicker. So altogether, it should cost around 9 passes, but it only costs 6! If you don't have enough passes, then I reccommend just getting the C.Timer because you can BLUP by 10 if you use it. The Nyx Pack is also one of the BMIs you must have on a skiller.
Water of Youth: Your horse doesn't age so fast and get old so quickly, so this reduces training time. Also, it lets you have twice as many lessons so you get more skills. You can buy it for a pass, and it's one of the musts for a skiller.
Piece of Cloud/Pieces of Cloud Pack: The Pieces of Cloud you can get for 1 pass in the Black Market, and they let your horse "de-age". This allows you to fit in more lessons, and get training done quicker. For a skiller, you need 20 Pieces of Cloud or the Pieces of Cloud pack. You can only get this pack if you have Pegasus Account. The pieces of Cloud Pack costs 5 passes, and it includes 20 Pieces of Clouds.
Achilles Heel: This is a great BMI. You can train much quicker because your horse can go to bed at midnight and be at 0% energy without damage to its health and wellbeing.
Philotes Stroke: You can use this instead of turnips, or use it with turnips and Achilles Heel to decrease training time.
Bonus Pack: As it states, this will give your horse a huge boost with bonuses and will improve it greatly.
If you have loads of passes and BMIs then great, use as many BMIs as you can!
