The druid "quad spells", at high levels are these:
Heliacal Flare (91)
Lunar Chill (92)
HelIacal Fire (96)
Frosthowl Chill (97)
All four are needed, due to the long 12-sec recast delay.
Obviously, they're fire and cold-based, unlike our earlier quad spells (Karana's Fury and the "Lightning" line), which were magic.
The lower level spells only hit 4 mobs at a time; these higher ones can hit 5. Also their aoe range is greater. I've casted them on a pack of mobs split into more than one group, with considerable distance between them, and the spell effect is evident on all of them.
Nice that EQ has given druids back the opportunity to pursue one of their "class-defining" abilities: quad-kiting, or as it should now be called, QUINT-KITING!
