First of all, I've really, really enjoyed my druid life so far. The firepower that the SLAs give is great, and the class has a uniqueness and versatility that I have come to love. I'm not sure how it plays in level 20+ content as most of what I have used seems to cap at ~level 15, but so far, so good.
That being said, I'm extremely disappointed with 9th level druid spells. Compared to other classes 9th levels spells they are worse than lackluster-most aren't worth loading, let alone casting. Compare them to meteor swarm, mass heal, energy drain, implosion, wail, etc. Hell, even mass hold/dominate monster...they are just not even CLOSE to the same level!
"Anger of the noonday sun"
Your fire spells give -5FR and -2% fort. WOW, great. TWO percent fort? total joke. It should be 10% minimum and even 20% would be reasonable considering how bad the elemental forms are...-3CL/MCL of most of your spells is pretty serious and TWO percent fort is really just cruel.
1/10 Near useless
"Mantle of the Icy Soul"
The targets of your cold spells take a 25% penalty to movement speed, a 10% penalty to attack speed, and a -4 penalty to reflex and fortitude saves. Actually, this sounds decent. Perhaps even a reason to use water elemental form...if it didn't gimp most of your spells and SLAs...
"Summon Nature's Ally IX"
Dryad or Elder Fire Elemental. Both were extremely mediocre even in very underleveled content.
It heals 1d6 hit points, +1 per caster levels (max +25), every 2 seconds for 8 seconds. Every two seconds 2 ability point damage is healed, and every three seconds one drained level and 1 bleed effect are removed. When the initial effect expires, a smaller healing effect that heals 2 HP every 5 seconds for 30 seconds is applied. Solid healing effect, and definitely worth using for raids and such, particularly for high amp targets. Removes negs as well!
8/10 Very good!
Storm of Vengeance
Conjures a storm with a massive thunderclap, deafening enemies, dousing them in acid rain, and lancing them with lightning bolts. Enemies within the cloud when it is first conjured are deafened for 3 seconds per caster level. Enemies within the storm take 8d6 acid damage every two seconds. Every 4 seconds, a random enemy within the storm takes 10d10 electricity damage (a successful reflex save halves). The storm lasts 3 seconds per caster level.
So...like a mid-level sorc casting acid rain, basically? The dps doesn't scale with caster level at all. And you get it as a SLA at level 18 anyway...so not particularly useful as a spell slot. Level9 spell as an SLA? Sounds ridiculous, but not when you realize it's basically the same power as a level 3-4 sorc spell. Imagine having wail/meteor swarm/mass heal/implosion as an SLA? Sounds too good to be true, because those spells are actually AWESOME, like lvl9 spells should be.
You attack enemies in your path, dealing an extra 3[W], and targets caught in your wake are frozen solid for 20 seconds. A successful reflex save negates the effect, and creatures caught in the ice can attempt fortitude saves to escape every 3 seconds. Creatures frozen are considered helpless, but they also gain DR/Adamantine 5. (DC 19 + WIS mod)
So if you're a caster, you most likely aren't in winter wolf form. If you're a melee druid, you probably are not wis based. Making a shapeshifting ability wisdom based is just a poor idea (ok, making any of the animal form attacks SPELLS are a stupid idea, but that is a different topic...) I really don't think 3[W] every 15 seconds is anything to write home about, even if it is AOE. Single target it probably lowers dps as it shoots you across the room
It's certainly possible that I am missing something awesome about some or all of these spells. But from what I can tell, and what everyone in-game I have talked to thinks as well...these spells just are a huge letdown.
