So, you thought in a different example, that if Alakazam had 6 in special attack and Mollesk used the move, it would reduce it to 5, and Mollesk would copy and double it, making it an impossible +10 boost?
Heh.
As for it hitting two targets, I just really like AOE. Doesn't everyone? Flexible targetting would be even better. ^^ Normally, projectile attacks don't split into two different directions and home onto a target. In a similar vein, most characters do not have arms long enough to attack foes far apart in that regards and sweep implies they muster enough burst of speed to hit two foes in a row, but going from one end to another is a... stretch.

Seperate tentacles though long enough to reach any foes and yet can control where they go unlike projectiles kinda justifies it on a thematic point.
Although if it gets to be an issue, we could start editting it by merely extending the range of targets. Like say, "Choose 2 targets with 6 slots of each other".
Other than that, do you think the move is plausible on a mechanic balance standpoint?
Keep in mind, that since it would only effect foes that would effectively suffer from morale loss, bosses would be uneffected by the effect. Unless we had a boss that could be scared like other living creatures. Hell, would be nice if we would get the fat ass Burkmont all tentacled up until he's drenched on the floor with his own drool practically comatose with fear and humiliation!
