* # Skill/Item Notetags:
* 1. <unison item actors: ids>
* - Sets the list of id of actors needed for the skill/item as ids
* , is used to separate the actor id in ids
* E.g.:
* <unison item actors: 1> means actor with id 1 is needed to use it
* <unison item actors: 4, 2> means actors with id 4 and 2 are
* needed to use it
* - All actors included in ids needs to be inputable, able to use the
* skills/item and pay its cost
* - All unison actors will pay the unison skill costs after using it
* - Only actors included in ids can select the skill/item
* - If ids only contains 1 actor id, this notetag will become only
* letting the actor with that actor id to use the skill/item
* 2. <unison item function rule: rule>
* - Sets the rule of setting user's function in the skill/item's
* damage formula as rule which is implemented by function
* RULES, which must be edited by opening this plugin js file
* directly
* - function must be a battler function name included in
* FUNCTIONS, which must be edited by opening this plugin js file
* directly
* 3. <unison item function actors: ids>
* - Sets user's function in the skill/item's damage formula to use
* its unison item rule to combine those of actors with id included
* in ids
* E.g.:
* <unison item atk actors: 1> means the user's atk in its damage
* formula uses that of actor with id 1 under the skill/item's
* unison rule applied to atk
* <unison item mat actors: 4, 2> means the user's mat in its damage
* formula uses those of actors with id 4 and 2 under the
* skill/item's unison rule applied to mat
* - function must be a battler function name included in
* FUNCTIONS, which must be edited by opening this plugin js file
* directly
* 4. (v1.01a+)<unison item actor mp cost: costs>
* - Sets the list of mp costs needed for each of the corresponding id
* of the unison actor in <unison item actors: ids>
* , is used to separate the mp costs in ids
* E.g.:
* If <unison item actors: 1> is used, then
* <unison item actor mp cost: 5> means actor with id 1 needs to pay
* the 5 mp cost for using the unison skill/item
* If <unison item actors: 4, 2> is used, then
* <unison item actor mp cost: 5, 10> means actor with id 4 and 2
* need to pay the 5 and 10 mp cost respectively for using the
* unison skill/item
* If <unison item actors: 4, 2> is used, then
* <unison item actor mp cost: 5> means actor with id 4 needs to pay
* the 5 mp cost while that with id 2 needs to pay the default
* skill/item mp cost for using the unison skill/item
* - MCR will be applied to the mp costs for all unison actors
* 5. (v1.01a+)<unison item actor tp cost: costs>
* - Sets the list of tp costs needed for each of the corresponding id
* of the unison actor in <unison item actors: ids>
* , is used to separate the tp costs in ids
* E.g.:
* If <unison item actors: 1> is used, then
* <unison item actor tp cost: 5> means actor with id 1 needs to pay
* the 5 tp cost for using the unison skill/item
* If <unison item actors: 4, 2> is used, then
* <unison item actor tp cost: 5, 10> means actor with id 4 and 2
* need to pay the 5 and 10 tp cost respectively for using the
* unison skill/item
* If <unison item actors: 4, 2> is used, then
* <unison item actor tp cost: 5> means actor with id 4 needs to pay
* the 5 tp cost while that with id 2 needs to pay the default
* skill/item tp cost for using the unison skill/item
* 6. (v1.02a+)<unison item actor learn: flags>
* - Sets the list of skill learn requirement flags for each of the
* corresponding id of the unison actor in <unison item actors: ids>
* , is used to separate the skill learn requirement flags
* Flag can be either t or f, meaning true or false respectively
* The default unison skill learn requirement is true
* This notetag only works on skills and has no effects on items
* E.g.:
* If <unison item actors: 1> is used, then
* <unison item actor skill learn: t> means actor with id 1 needs to
* learn the skill in order to use it
* If <unison item actors: 4, 2> is used, then
* <unison item actor skill learn: t, f> means actor with id 4 needs
* to learn the skill in order to use it while actor with id 2
* doesn't need to
* If <unison item actors: 4, 2> is used, then
* <unison item actor skill learn: f> means actor with id 4 doesn't
* need to learn the skill in order to use it while actor with id 2
* needs to due to the default unison skill learn requirement
* 7. (v1.02a+)<async unison item>
* - Sets the unison skill/item to be inputable when any battler
* needed for that skill/item is inputable
* - That skill/item and all battlers inputted it will wait for all
* battlers needed for that skill/item to input it in order for them
* to execute it altogether
* - This notetag will be ignored in the default RMMV battle system
* and all unison skills/items will be synchronous ones
* - This notetag will be ignored in ATB systems that will always wait
* when there are inputable actors and all unison skills/items will
* be asynchronous ones
* 8. (v1.03a+)<unison item actor function drain: weights>
* - Sets user's drained hp/mp/etc for skills/items draining hp/mp/etc
* to use redistribute the drained hp/mp/etc to all those of actors
* with id included in ids in <unison item actors: ids>
* - function must be a battler getter name
* - The redistribution amount to each actor is the minimum value of
* the corresponding weight / sum of weights and the difference
* between the hp and the mhp
* - If the sum of weights is 0, then no actor will receive any amount
* of the drained hp/mp/etc
* - All the undistributed drained hp/mp/etc will be taken by the
* unison invoker, and any amount left by the unison invoker will be
* lost
* E.g.:
* If <unison item actors: 1> is used, then
* <unison item actor hp drain: 0> means actor with id 1 won't
* receive any drained hp from skills/items draining hp
* If <unison item actors: 4, 2> is used, then
* <unison item actor mp drain: 1, 2> means actor with id 4 and 2
* will receive 1/3 and 2/3 of the drained mp from skills/items
* draining mp respectively
* If <unison item actors: 4, 2> is used, then
* <unison item actor mp cost: 1> means actor with id 4 and 2 will
* receive 100% and 0% of the drained mp from skills/items draining
* mp respectively
