Slap

Slap (スマック, Smack) is a Jupiter Utility Psynergy introduced in. It can also be used in battle as a stand-alone offensive Psynergy. Its encyclopedia entry reads as follows:
 * "This wind-based Psynergy conjures a blast of air with unusual properties. It's good for knocking things around or waking up sleeping people."

Basic Description
Slap is an offensive, single-target Psynergy. The final amount of damage is determined by comparing the caster's Jupiter Power to the target's Jupiter Resistance, and using the difference to modify the base power of Slap.

Visually, Slap resembles a large, blue, disembodied hand that appears and forcefully slaps the target before disappearing.

As a Utility Psynergy
Slap is a plot-important Utility Psynergy used to deliver a slap to an object at a distance, functioning somewhat similarly to Force. Slap can be used to wake up sleeping characters or creatures, knock down dangling things, and "tweak the noses" of several statues to cause them to respond. More importantly, Slap is required to progress further in the game, as it is required in order to wake up the Mountain Roc, which triggers certain cutscenes.

Availability
Slap is available to any Adept that has equipped the Slap Glove. In absence of the Slap Glove, the move is known naturally by the Jupiter Adept Sveta. Due to Slap's Utility Psynergy status, she will retain access to it regardless of her current class.

Analysis
General: Slap is a fairly weak-powered move, equivalent to early game Psynergies. It generally has little in-battle use; however, the chance to Stun an enemy can be useful if inflicted.

By Game
During the battle with the Mountain Roc (and only during this battle), Slap has the special ability to negate the Mountain Roc's Stone Molt ability, which allows it to regenerate HP. Afterwards, only Sveta will be able to use Slap. However, its relative weakness in comparison to Sveta's stronger abilities means Slap will be used rarely, if at all.

Trivia

 * According to Tret and Laurel, Slap only occurs naturally among Beastmen Adepts. However, the reason for this exclusivity remains unknown.
