Paper Heron is a Limited 6-star Arcanist of the Plant Afflatus and is the shiny new puzzle piece for the often out meta Impromptu Incantation Archetype team. Paper Heron’s ability allows her to convert the normal Impromptu Incantation into a special Plant Afflatus Incantation with AoE damage and powerful effects, helping to elevate the Impromptu Incantation back into meta relevance by simply existing in the team.

Reverse: 1999 Paper Heron

To understand how Paper Heron works and how to best build her into a powerful Arcanist, we need to know how her Skill and Ultimate works:

Shaper of Qi
(Incantation Skill)
RankEffects
1Mass attack. Deals 200% Reality DMG to 2 enemies. After attacking, consume 2 [Eureka] to increase the number of [Impromptu Incantation] attacks by 1 this round.

3Mass attack. Deals 500% Reality DMG to 2 enemies. After attacking, consume 2 [Eureka] to increase the number of [Impromptu Incantation] attacks by 1 this round.
Importance: High
Analysis: Paper Heron’s main damage output that allows her to convert Eureka into more damage output for the Impromptu Incantation by increasing its attack amounts.
Reader of Qi
(Incantation Skill)
RankEffects
1Mass buff. Grants self 2 stacks of [Valley Wind] and all allies [Auspicious Wind] for 2 rounds. Consumes 2 [Eureka] to increase the DMG Dealt of [Impromptu Incantation] by +20%  this round.
2Mass buff. Grants self 2 stacks of [Valley Wind] and all allies [Auspicious Wind] for 2 rounds. Consumes 2 [Eureka] to increase the DMG Dealt of [Impromptu Incantation] by +25%  this round.
3Mass buff. Grants self 2 stacks of [Valley Wind] and all allies [Auspicious Wind] for 2 rounds. Consumes 2 [Eureka] to increase the DMG Dealt of [Impromptu Incantation] by +30%  this round.
Importance: Highest
Analysis: Paper Heron’s main enabling and buffing Incantation Skill that allows her to massively boost the Incantation damage output of other allies while also help maximize the Impromptu Incantation damage.
One Paper, Five Armies (Ultimate)Effects
Mass attack. Grants 2 [Eureka] to caster. Deals 750% Reality DMG to all enemies. For each [Eureka] possessed by the caster, this attack’s Ultimate Might is increased by +15%. After attacking, add 8 [Inspiration] to this round’s [Impromptu Incantation], and increase the level of [Glimpse of Tao] by 1. 
Importance: High
Analysis: Paper Heron’s Ultimate allows her to level up her important Array effect and grant her the much needed Eureka stacks to help fuel the Impromptu Incantation.

Additionally to her skills and abilities, her inheritance level will also affect Paper Heron’ performance in a team:

RankEffectsAnalysis
1Whenever an ally consumes [Eureka], accumulate points of [Inspiration]. Paper Heron increases the likelihood of [Inspiration] points being distributed onto attack-type incantations. The maximum points of [Inspiration] that can be allocated to basic Incantations is increased. At the start of the round, Paper Heron restores all [Eureka] to self and grants [Eureka] to allies.
[Impromptu Incantation] is now of the Plant Afflatus and deals Reality DMG. It splits its attacks, selecting additional targets; the fewer targets, the higher the DMG Dealt by [Impromptu Incantation].
Insight I
Upon entering combat, Paper Heron deploys the [Qi Panorama] array. After casting Ultimate, if not under [Qi Panorama], deploy it. Max [Eureka] is increased.
Paper Heron’s main gimmick as a character, with the ability allowing her to deploy a special array upon entering the battlefield that converts normal Impromptu Incantation into her special Plant Afflatus Impromptu Incantation that deals damage to all enemies based on the amount of Inspiration Points.
2Upon entering combat, ATK +5%.A good insight that boosts Paper Heron’s attack stat.
3Upon entering combat, grant other allies [True Guidance]. Increase the level of [Glimpse of the Tao] for every [Inspiration] ally present (up to level 3). Increases the Incantation Might of [Impromptu Incantation] while [Qi Panorama] is active equal to (current level of [Glimpse of Tao] * 5)%.This ability essentially allows Paper Heron to instantly level her Array up to level 3 immediately if the team has 3 Inspiration Characters and help boost the overall damage output of the Impromptu Incantation based on her Array level.

Paper Heron is a Limited Arcanist that specializes in enabling an entirely brand new flavor of Impromptu teams in Reverse:1999 commonly known as the Plant Impromptu team or the Green Impromptu team. This is thanks to her ability to convert the normal typical Impromptu Incantation effect and turn it into a more powerful version that deals Plant Afflatus damage to enemies.

Paper Heron’s gameplay is relatively simple, with her skill kit revolving around enabling the team by taking into account the Eureka stacks generated by the entire team and herself in order to boost the damage output of the team through the Impromptu Incantation. Upon entering the field, Paper Heron will enable a special Array effect, which converts the usual Impromptu Incantation from the usual Star Afflatus single target attack into a Plant Afflatus AoE Attack. This Impromptu Incantation effect functions similarly to the usual Impromptu Incantation, except that it can only hit up to 3 times, with any excess attack instead increasing its damage output and it deals more damage to enemies the less enemies there are on the field. 

Paper Heron’s Incantation Skills and Ultimate help the entire team and herself generate Eureka stacks in order to fuel the Impromptu Incantation while also allowing her to boost the damage of the incantation massively before unleashing the Impromptu Incantation onto the enemies. By having Paper Heron, players can make a very strong Impromptu Incantation team that not only can deal damage to all enemies, but also can deal massive amounts of damage to both waves of enemies and bosses thanks to the unique effects of Paper Heron.

As a main DPS and enabler for the brand new Impromptu team, Paper Heron wants Psychubes that takes into account Eureka stacks in order to allow the entire team and the Impromptu Incantation to deal more damage overall to enemies.

The best Psychube for Paper Heron is her signature:

Wayfarer of The Tao
EffectFor every [Eureka] an ally consumes, all allies gain +0.2% DMG Dealt (stacks up to 30 times). If the user is of the [Plant] Afflatus, when setting an Array, it also increases all allies’ Incantation Might by +6%. This effect is removed when the Array ends or gets replaced.
AnalysisPaper Heron’s signature Psychube that help boost the entire team’s damage output while her array is active.

For alternative Psychubes, players can consider using these options until you get her Signature Psychubes:

Addio Coda
EffectWhen an ally consumes Eureka, accumulate points of [Inspiration].
Whenever an ally consumes 1 Eureka, all allies gain DMG Dealt +0.3%, stacking up to 20 times; if the carrier is of the [Star] afflatus, after taking an action, [Impromptu Incantation] gains attack instance +1 for the round, this effect can trigger up to 1 time per round.
AnalysisThis alternative Psychube helps Paper Heron gains more Inspiration stacks while also boosting the team’s damage output.

For Paper Heron, as her main damage output is from her Incantation Skill and the Impromptu Incantation, it is important for players to boost the overall offensive stats for Paper Heron to optimize her damage output.

Players should use the Hyper piece as her main Resonance piece for extra attack stats.

Yes. You Should. Not only does Paper Heron enable the old Impromptu Incantation team to become meta again with her amazing abilities and skill kit, Paper Heron herself is one of the better enabler characters in the game right now. By having Paper Heron, players can almost guaranteed to be able to play the Impromptu Incantation team with many different characters and support in the future as her skill kit very foolproof overall with the ability to not only enable but also boost the overall damage output of any Impromptu Incantation teams. 

Therefore, if players want to start building a Impromptu centric team or want to invest in one in the future, getting Paper Heron is highly recommended as she is a Limited Character.

Overall Paper Heron’s Portrait levels help her to enhance the effects and overall damage output of her special Plant Afflatus Impromptu Incantation. Paper Heron’s portrait helps to both boost the overall damage output of the Impromptu Incantation damage against enemies but also allows the Impromptu Incantation to have more hits based on her Portrait levels.

That being said, while her Portrait levels can help improve her overall damage output by quite a lot, it doesn’t really affect her overall damage rotation or gameplay and only improve in damage output. Therefore, players should only invest in portrait levels for Paper Heron if they want to optimize her damage output to the fullest. For F2P players, P0 or P1 is enough for Paper Heron to function as one of the best characters in the game. However, for high level investments, players should aim to get to either P2 for low spenders or P5 for whales to optimize her damage output.

The brand new character that returns Impromptu teams back to the meta, the limited character Paper Heron makes her grand debut in Reverse:1999 . If players want to try out this brand new limited character, then don’t hesitate to roll on Paper Heron’s banner with the help of Enjoygm – the best Reverse: 1999 Top Up site on the web!
