Fireball.js

/* Usage: /:Fireball or /:Fireball
 * copy this macro and rename it to match other spells, then reference it in an OtF like this: [/:spellname]
 * then fill in the values below to match the name of the spell, the ranged attack, the animations, and outcomes.
 * the example success formulas use the SpellDamage macro

 * Modifiers:
 * 	GURPS.gmod  /roll [-2 due to poor footing]
 * GURPS.ModifierBucket.currentSum()
 * let myActor = _token.actor
 * GURPS.findAttack(actor, sname, isMelee,isRanged)
  * GURPS.findAttack(_token.actor, 'Fireball', False, True)
