CHAIN LIGHTNING

Strike an enemy with lightning. Three more bolts leap from the target, electrifying as many as three other enemies within range.

Range: 18m (60ft) Save: DEX save

When to cast Chain Lightning

Cast it whenever there are four enemies to hit. That is 40d8 total, an average of 180 damage spread across the four biggest threats in the room, and none of it touches your party because it only jumps to enemies. Fireball has to be aimed around your melee. This does not.

It is single-target on the first bolt, so the initial hit can be aimed at whichever enemy you most want dead, and the chains pick up the rest. Against a boss with adds, the boss takes the first bolt and the adds take the chains.

Lightning is resisted by a handful of things, mostly elementals and some constructs, and it electrifies water. If the enemy is standing in a puddle, everyone in the puddle gets a bonus shock.

Twinned Spell does not work on it any more, but you do not need it to. With a Level 6 slot this is what a Sorcerer or Wizard should be casting on turn one of any real fight.
