Shackle Ring

Shackle Ring is an in Xenoblade Chronicles 3. It provides beneficial effects when different s (including s) are used in short succession. The Chain Ring is a weaker version of this accessory.

Mechanics
The Shackle Ring works by building up a list of the previous several Arts used. The accessory provides stronger bonuses the more Arts are in the list (mostly; see ).

Using an Art in any of the following cases will clear the current list and start a new list with the Art used, removing the built-up bonuses: The maximum length of the list depends upon the rarity of the Shackle Ring: 6, 7, and 8 for the Common, Rare, and Legendary versions respectively. The legendary version has a maximum list length of 8 despite each character only having 7 unique Arts (meaning that the list can never actually have 8 Arts in it at once).
 * The Art in question is already in the list.
 * The Art was initiated more than 15 frames (0.5 seconds) after the end of the previous Art (that being when control of the player is regained). If the Art did not end because it was blocked, the list is still cleared. Cancelling ignores this rule.
 * The list was at its maximum length before the Art is used.

This means that to use the accessory most effectively, one must use a string of different Arts with no repeats, and try to cancel whenever possible. When using (for example) a common-version Shackle Ring in this way, the first Art used will be unaffected, the second will be slightly stronger, the third stronger still, and so on up until the sixth — assuming no Art was used twice. If a seventh Art is used immediately afterwards, it will receive no benefits from the ring even if it was the one not used previously in the string of Arts, due to the common version of the Shackle Ring having a maximum list length of 6. However, using it will start a new string, allowing the previously-used Arts to receive bonuses again from their use.

Using a Fusion Art only adds the relevant Class Art to the list. The accessory has no effect during s or when in Ouroboros form.

Benefits
The following properties of Arts are improved by the Shackle Ring:
 * (The damage is increased by an independent multiplier, making this effect particularly strong among damage increases.)
 * Healing (for Arts that directly heal the target)
 * ,, Field Art, and Art Combo duration
 * and success rate
 * Range of area-of-effect moves

The strength of the benefit depends upon how many Arts are in the accessory's current list (see above): The list always includes the Art in question, so it is always of length 1 or greater. Having 7 Arts in the current list results in no benefits (this is only achievable by using all of the character's Class Arts, Master Arts, and in succession).
