Points

Stream Currency
Xizta's stream uses two types of points, Xizta Points (XP) and Action Points (AP). XP is more of a short term minor interaction type of point system, where AP has a more long term effect.

XP is gained at 1XP per 1 minute in the stream, or 2XP per 1 minute as a subscriber. Every time a bit boss is defeated, the chat earns 600 XP. XP resets at the end of every month.

AP is more of a premium currency gained at 1AP per $1 Donation. Alternatively you can earn AP for free by converting 600 XP per 1 AP. AP never resets.

XP Rewards
A list of sounds that can be played using XP can be found here.

AP Rewards
These Rewards will be retired on March 3rd 2018 or sooner. Some of which will not be returning, like anthem, or lickit, but most will come back in some form with cost adjustments.
