Mount Bolster

Bolster improves the equip and combat powers of your mounts by up to 100% (double the value). The quality of your 10 best mounts counts toward bolster, for a maximum of +100% bonuses with 10 Mythic mounts. Here are the numbers:

• Common: +0.5%

• Uncommon: +1%

• Rare: +2

• Epic: +3%

• Legendary: +5%

• Mythic: +10%

Bolster is not a priority. It is nice to have but very expensive.

Note that the way numbers are displayed in-game for Combat and Equip Powers is a bit messy : your bolster is always accounted for, but the powers are displayed either at the level you have them (if you do have them) or at Mythic (if you do not have them). It can be tricky to compare different powers in-game due to this. Combat and Equip powers can even be displayed at different qualities on the same mount in the Auction House or Collection.
