The base cost of Boosting varies depending on hero Rarity and Level. There is no limit to boosting other than availability of Soul Dust, however each Boost will cost 4x the Soul Dust used for the prior boost for each activation on the same Hero. Boosting lasts for 24 hours except during Global Events or related Fables, during which they last 48 hours and may cost less Soul Dust (Up to 30% for fables, and 50% for event featured heroes). Applying another boost to an already boosted hero will refresh the duration of all boosts currently affecting that hero. The Guild Bonus Masterful Enchantment can also be activated to reduce the cost for boosting.
