Battle Rating

Battle Rating (often abbreviated "BR" or "br") is essentially the overall strength rating of your character. It is determined by numerous factors. The higher your Battle Rating, the stronger you become. If you are in a guild, your Battle Rating adds to the overall Battle Rating of your guild.

There are many ways to improve your Battle Rating:

Refining

Your gear comes (most of the time) with 5 random stats assigned to it. These stats add to your BR and contribute to your build. Refining these stats can make a chip in the window into a great big crack. Properly refined gear helps. For example - a mage using will destroyer has no need of any crit - refining will let you remove the crit and replace it something else. Refinement crystal shortage? Try using some excess insignias to purchase the 300 insignia brooch from the arena shop for a refinement roll! 

Gems

You can socket gems to you armor to have a higher battle rating. Also, leveling up your soul engraving will boost the stats you get from gems as well, boosting your battle rating even higher.

Astrals

Astrals can form a significant portion of your battle rating. As such it’s important to keep spending gold on them, be it in huge chunks over days, or a little bit everyday. This will keep them levelling up and making them stronger. 

Mount Training

The more mounts you have and the higher the stable, the better.

Guild Skills

Learned in the Guild Tower, payed with contribution points. (Gold)

Academy Tech

While it may not seem it at first, your Academy eventually forms a big factor in your strength. Its potential keeps increasing as you level up. However: It takes a lot of kyanite (and time for non VIP) to max out, slow levelling helps this process as you’ll get more kyanite and time per level.
